Our Vocation Is Peacebuilding (Construo pacem est nostra vocatione)1 

 

GERARD F. POWERS

“Our vocation is peacebuilding.” That would be a fitting theme for a new synod and apostolic 

exhortation. This synod could address the future of the just war tradition for the Catholic 

community, and do so in a way that situates the just war tradition where it should be: as just one, 

relatively marginal element of a much wider and more important project of strengthening 

peacebuilding. With the Sermon on the Mount at the center and drawing on a rich tradition of 

reflection on war and peace, the synod could offer a spiritual, theological, moral, and pastoral 

template for a Catholic community animated by a deep and abiding commitment to peacebuilding. 

As I envision it, the synod would insist that moving peacebuilding from the margins to the center 

of Catholic identity and practice is necessary for the Catholic community’s integrity as well as its 

capacity to work with other religious and secular actors in addressing the world’s most pressing 

challenges to peace. 

A proposed synod on peacebuilding parallels Pax Christi’s call, following its 2016 conference 

on nonviolence with the Pontifical Council for Justice and Peace, for a synod on nonviolence and 

just peace. While an encyclical would be welcome, a synodal process, preferably including 

diocesan and national synods leading to an ordinary general assembly, would permit the wide 

consultations needed to address the varied and contingent dynamics of conflict and peace around 

the world. And the process itself would help achieve one of the goals of the synod: to broaden and 

deepen Catholic engagement in peacebuilding. Like Pax Christi’s proposed encyclical, the synod 

would take a “Just Peace approach [that] offers a vision and an ethic to build peace as well as to 

prevent, defuse, and to heal the damage of violent conflict.”2 But the theme of the synod would be 

the vocation of peacebuilding: just peace is the vision and moral framework; peacebuilding is what 

we are called to do; and peacebuilders are what we are called to be if the world is to move toward 

a just peace. Peacebuilding reinforces the idea that a just peace is not a static end-goal achieved by 

implementing a set of principles or developing just structures. Rather, just peace is something that 

we must constantly build and rebuild, a dynamic process of contingent efforts to achieve 



127  Powers 
 

communities of right relations in many different places and at many different levels of society.3 

Unlike Pax Christi’s proposal, a primary purpose of this synod would not be to commit the 

Church “no longer [to] use or teach ‘just war theory.’” The synod certainly would contribute to 

the increasing emphasis in the Church’s teaching and practice on the importance and efficacy of 

nonviolence. But it would be clear that “Gospel nonviolence” is just one element of peacebuilding. 

Peacebuilding is not an alternative to the Church’s restrictive approach to the just war tradition, 

but a necessary complement to it. The synod would highlight the need for both adherents of 

nonviolence and just war to enlarge the conversation by reflecting much more seriously and 

systematically than either have done to date on peacebuilding, an area where they should be able 

to find common ground. 

In this essay, I will first argue that a synod is needed to address gaps that keep peacebuilding 

on the margins of the Church. I will then address four ways a synod could address those gaps in 

an effort to become more of a peacebuilding Church: (1) renewing a commitment to the vocation 

of peacebuilding, (2) further developing a peacebuilding ethic informed by practice, (3) 

understanding the distinctive contributions of Catholic peacebuilding as a basis for broader 

engagement with the world, and (4) clarifying the complementary relationship between 

peacebuilding, nonviolence, and the just war tradition. 

 

Why a synod? 

If Catholic social teaching is the Church’s best kept secret, peacebuilding is Catholic social 

teaching’s best kept secret. Much as Laudato si’ did for the environment, a synod on peacebuilding 

would help address gaps in Catholic teaching and formation and help mainstream peacebuilding 

practices that, while impressive, are mostly marginal activities within the Church. 

One gap is the literacy gap. From the Sermon on the Mount and official Catholic social teaching 

to spiritualities and sacraments, peace is a central theme. Yet, few Catholics, even clergy and laity 

with formal training in theology, know the Church’s rich tradition of peace and understand how it 

might apply to today’s world. How many graduates of Catholic universities have even a cursory 

understanding of this tradition? How many priests and bishops have taken a seminary course on 

the subject? An increasing number of Catholic universities have peace studies programs, but, as 

with other academic disciplines, engagement with the Catholic intellectual tradition and practice 

is often minimal and ad hoc. The relatively few Catholic dioceses and parishes that address issues 



Our Vocation Is Peacebuilding  128 
 

of war and peace usually do so during national debates about U.S. military intervention, a 

“teachable moment” that easily dissolves into political polarization, not enhanced understanding 

of the tradition. 

A second gap is that, despite the Church’s rich tradition, important aspects of a peacebuilding 

ethic are underdeveloped. Just as just war norms are often racing to keep pace with new technology 

and new strategies of warfare, a peacebuilding ethic needs to catch up to the practice of 

peacebuilding.4 A synod could solidify, clarify, and deepen existing teaching by reflecting on the 

insights gained from a wealth of peacebuilding experience. Moreover, it could catalyze further 

reflection on today’s new challenges of peace, from the moral dilemmas involved in sustainable 

peace processes to issues of self-determination and nation-building, which are at the heart of some 

of the world’s most intractable conflicts. 

Finally, perhaps the major gap is that the practice of Catholic peacebuilding is so rare. No doubt, 

the Catholic peacebuilding slate is hardly blank. Within the Catholic community, as with other 

faith communities and secular actors, peacebuilding has become a kind of cottage industry, with a 

proliferation of programs that seek to nurture, expand, and professionalize the kinds of 

peacebuilding activities in which the Church has long been involved. Sant’Egidio’s peacebuilding 

work in Mozambique and elsewhere is a notable example, as are endless kinds of peacebuilding 

activities by Church peace and justice entities, from parishes and religious orders to episcopal 

conferences and the Holy See. Less well known are the peacebuilding activities of Catholic Relief 

Services and other Caritas agencies, which have developed well-funded, long-term peacebuilding 

programs.5 As impressive as this work is, however, much of it consists of relatively modest, ad 

hoc initiatives run by a relatively small group of bishops, specialists, activists, and programs. For 

many Catholic faithful and institutions, peacebuilding is not considered integral to their Christian 

identity or mission and does not enjoy significant commitment of resources. The United States 

remains mired in Afghanistan and Iraq, the two longest wars in its history, yet, with a few 

exceptions—e.g., occasional statements by U.S. bishops and a few Catholic peace and human 

rights groups, and humanitarian aid and refugee resettlement programs—the Catholic community, 

like most Americans, acts as if the nation is at peace. 

To help address these gaps, a synod could highlight four main topics: (1) the vocation of 

peacebuilding, (2) a practical theology of peacebuilding, (3) the distinctiveness of Catholic 

approaches, and (4) the complementarity of nonviolence, just war, and peacebuilding.

Peacebuilding is our vocation 

The central theme of the synod would be peacebuilding as vocation. No development of the 

tradition is needed for peacebuilding to be considered integral to an understanding of the Christian 

vocation and therefore central to the Church’s mission. In his exhortation after the African Synod, 

Pope Benedict summarized the link between faith and peacebuilding as follows:  

 

Christians will thus become peacemakers (cf. Mt 5:9) to the extent that, grounded 

in divine grace, they cooperate with their Maker in creating and fostering the gift 

of peace. As reconciled men and women, the faithful will also promote justice 

everywhere, especially in African societies divided and threatened by violence and 

war, yet hungering and thirsting for true justice […]. Open to the prompting of the 

Holy Spirit who continues to awaken different charisms in the Church, Christians 

must pursue or undertake with determination the path of holiness, and thus 

increasingly become apostles of reconciliation, justice and peace.6 

 

Robert Schreiter suggests three mutually reinforcing dimensions of the vocation of peacebuilding: 

(1) a spiritual vision of peace; (2) a set of tasks and practices of clergy and laity that correspond to 

the offices of teaching (e.g., education for peace), shepherding or governing (e.g., facilitating peace 

processes), and sanctifying (e.g., rituals of forgiveness); and (3) a set of spiritual disciplines (e.g., 

the sacraments, prayer, maintaining hope).7 

Understanding the dynamics of conflict, training in conflict resolution skills, educating to 

change attitudes, and developing strategies of social change are essential. But understanding 

peacebuilding as vocation gives this work a depth and texture that are essential for effective, 

sustained peacebuilding, especially amidst seemingly hopeless, intractable conflicts. Understand-

ing peacebuilding as vocation also enriches the Church’s wider teachings and practices, from 

sacraments and systematics to human rights and development. 

Drawing on its broad consultative process, the synod could highlight concrete examples of how 

the vocation of peacebuilding is being lived out around the world through a wide variety of 

charisms. It could highlight bishops and priests who engage in what secular experts would consider 

mediation or conflict transformation, but which the bishops and priests consider pastoral 

engagement or accompaniment. In Sudan, for example, 



Our Vocation Is Peacebuilding  130 
 

Church leaders did not consider themselves to be “peacebuilders.” They considered 

themselves pastors and shepherds, whose first obligation was to reflect Christ’s 

fidelity to the Church through their own fidelity to the people. As pastors, they 

created and sustained communities of faith that could absorb suffering, embody 

forgiveness and reconciliation, maintain hope, and advocate for justice. As 

shepherds, they gave voice to the voiceless and spoke truth to power.8 

 

Unfortunately, this kind of pastoral engagement is too often the exception, especially in places 

where violent conflict is not a daily reality. That is the main reason it is necessary to revive 

peacebuilding as vocation. A synod could remind the clergy that too many priests and bishops are 

not responding to Pope Francis’ insistence that they escape the confines of their comfortable 

rectories and chanceries and get out into the streets. 

The synod also could address challenges that arise when bishops and priests are out in the 

streets. Frequently, Catholic clergy and institutions are called to play leading roles in official truth 

and reconciliation or human rights commissions, constitutional reform initiatives, election 

monitoring, and negotiations between conflicting political parties or armed groups. Because these 

roles are inherently political, clergy sometimes decline to accept them. Especially in countries like 

Congo and South Sudan, however, where the Church is one of the only functioning and widely 

respected institutions and where there is a dearth of educated laity, clerics often reluctantly take 

up the mantle under the rationale that the extraordinary circumstances justify what is sometimes 

referred to as a “substitute political role.” When they do so, they must walk a tightrope between 

the religious and the political. This kind of direct political engagement by Church leaders can be 

necessary and effective in the short-term. But it always carries the risk of politicizing religion and 

clericalizing peacebuilding. A synod could mine the experience of the Church around the world in 

these situations and further elaborate ecclesiological and practical criteria for when it might be 

appropriate for the institutional Church or individual clerics to play this substitute political role 

and when to refrain from doing so. 

By far the biggest challenge a synod could address is that revitalizing the peacebuilding 

vocation depends on revitalizing the lay vocation. Revitalizing the lay vocation, in turn, requires 

overcoming the strong tendency in the Church and the wider society to privatize religion, to create 

a sharp separation between what people pray on Sunday and what they do on Monday. Inculcating 



131  Powers 
 

peacebuilding as a vocation is possible only if Catholics can accept that social teaching and action 

are integral to their faith. Lay Catholics are meant to be the vanguard of a peacebuilding Church 

because, as “ambassadors of Christ” (2 Cor 5:20) in the public sphere, they have the principal 

responsibility for transforming the social order in light of the gospel through their work, family, 

and civic engagement.9 The synod could illustrate the lay vocation in action with concrete 

examples of the variety of ways in which lay people and lay organizations have embraced, 

nurtured, and lived out the peacebuilding vocation.  

The synod also could acknowledge that too often the laity are missing-in-action when it comes 

to peacebuilding. It could cite the bishops of the Great Lakes Region of Africa, who have rightly 

identified the problem as one of evangelization. In a strategic plan approved by the six national 

and two regional episcopal conferences in the Great Lakes Region, they bemoaned the fact that 

“[w]e have not always done what we could in order to form the laity for life in society, to a 

Christian vision of politics and economics. A protracted absence of the lay faithful from this field 

has led them to believe that the faith has nothing to do with politics.”10 They concluded that action 

to promote peace and reconciliation requires finding “the language and methods which are 

necessary to form communities in an active faith which brings about a social and political 

revival.”11 

Just as the bishops of the Great Lakes Region committed to re-evangelize the laity regarding 

the lay vocation, a synod should commit the Church to a renewed Church-wide effort of formation. 

A synod could applaud the proliferation of peace and justice initiatives at all levels of the Church 

since Gaudium et spes called for undertaking “an evaluation of war with a new attitude,” 

strengthening programs to study peace, and renewing efforts to construct peace by international 

Catholic associations.12 In the same spirit, it could call for a renewal of the Church’s commitment 

to peacebuilding with an entirely new attitude. Among other things, a synod could commit to new 

programs of priestly and episcopal formation to reinforce the centrality of peacebuilding in their 

ministry. It could call on Catholic institutions, from episcopal conferences, dioceses, and parishes 

to Caritas agencies, educational institutions, and religious orders, to do an audit of the role of 

peacebuilding in their work and to develop plans for making it more integral to that work. 

Moreover, it could encourage lay movements to do more to integrate peacebuilding into their work 

and could call for a proliferation of lay Catholic groups, such as Sant’Egidio and Pax Christi 

International, that have special competencies in peacebuilding. 



Our Vocation Is Peacebuilding  132 
 

A practical theology and ethic of peacebuilding 

Revitalizing the vocation of peacebuilding is the critical foundation for becoming more of a 

peacebuilding Church, but further development of the tradition is needed to address new 

challenges. A synod could contribute to and call for further development of what Robert Schreiter 

calls a practical theology of peacebuilding, “an ongoing practice of reflection and action that keeps 

theory and informed practice in constant conversation with each other.”13 The synodal process of 

world-wide consultation would enable the Catholic community to undertake a systematic reading 

of the peacebuilding “signs of the times” that would deepen understanding of the nature of 

contemporary conflicts, contribute to mapping and analyzing the mostly unheralded peacebuilding 

work of the Catholic community, and identify ways in which existing teaching can be enriched by 

insights from practice and practice can be enriched by developments in teaching. While it is hard 

to predict in advance what issues would emerge from a synodal process, the Catholic 

Peacebuilding Network (CPN), a network of two dozen Catholic academic institutes, development 

agencies, lay organizations, and episcopal conferences, has identified several areas where further 

development of a practical theology of peacebuilding is needed.14 

One area is the role of conflict resolution and dialogue. Kenneth Himes suggests that the 

presumption against war and the positive conception of peace found in Catholic teaching is not 

matched by “a comparable set of theological and ethical principles to guide conflict resolution.”15 

According to Himes, Catholic communitarianism is overly optimistic about the efficacy of 

dialogue in overcoming deep-seated conflicts and, thus, remains underdeveloped in conflict 

resolution, despite its engagement in such efforts around the world.16 Catholic social teaching 

could benefit from more engagement with the fields of international relations and international 

law, as well as the newer disciplines of conflict resolution and conflict transformation, in 

developing more substantive norms for what is called “Track One” or government-to-government 

diplomacy, as well as the Church’s own rather impressive record of “Track Two” diplomacy, 

which involves non-state actors. Much has been written on the Sant’Egidio Community’s role in 

ending the Mozambique conflict.17 Also ripe for reflection are the ways in which theology, social 

teachings, rituals, and pastoral practices contribute to formal and informal peace processes in 

Colombia, the Philippines, Uganda, Congo, Sudan, and elsewhere.18 A synod could also address 

such recurring moral dilemmas as finding the right balance between justice (holding bad actors 

accountable so as to end a culture of impunity and break the cycle of violence) and peace (granting 



133  Powers 
 

amnesties and power sharing in order to achieve a peace agreement). Finding the right balance has 

to be done on a case-by-case basis, but these kinds of issues are a largely unexamined dimension 

of Catholic peacebuilding that warrant at least as much reflection as they are given in the secular 

literature.  

A second issue that deserves fuller treatment is self-determination and nation-building. The 

religious-ethnic-nationalist conflicts since the end of the Cold War have generated a substantial 

literature on religion and violence, religion and ethnic-national identity, and the legitimacy of 

humanitarian intervention. But the issue that is at the heart of so many of these conflicts—disputes 

over self-determination and secession—has not been addressed to the same extent. The Church has 

been deeply engaged in debates over self-determination and secession in individual cases, but there 

is little in official Catholic teaching on the topic.19 A synod could lead to the development of a 

more consistent and coherent moral framework to guide the Church’s engagement. 

Nuclear disarmament is a third issue. The nuclear age has generated an abundance of Church 

statements and scholarly reflection on the ethics of nuclear weapons. Relying heavily on just war 

arguments, Pope Francis recently condemned not only the use, but also the possession of nuclear 

weapons.20 This statement and the Holy See’s ratification of a new treaty banning nuclear weapons 

are part of a long-standing strategy of the Holy See to delegitimize nuclear weapons. The continued 

success of this strategy will require the development of an ethics of nuclear disarmament that is as 

sophisticated as the ethics of nuclear use and deterrence. For example, more reflection is needed 

on what forms of deterrence would be morally acceptable to deter nuclear breakout in a world near 

or at zero nuclear weapons, as well as on the elements of an ethic of cooperative security that could 

make “global zero” feasible.21 More reflection is also needed on the pastoral implications, 

especially for Catholic policymakers and military personnel, of the Church’s recent condemnations 

of both nuclear use and nuclear deterrence. 

These and other issues marry political ethics, economic ethics, business ethics, environmental 

ethics, international law, and cultural norms, all of which must find expression in institutions. What 

is needed, therefore, is greater attention to an ethic of institutions that can translate norms into fair 

and effective structures and processes that are essential to building a just peace. This involves a 

multifaceted, building block approach to peacebuilding that a synod can model and encourage. 

 

 



Our Vocation Is Peacebuilding  134 
 

A distinctive Catholic peacebuilding 

Since Pacem in terris, social encyclicals have been addressed to all people of good will, not just 

Catholics. In Laudato si’, Pope Francis not only addressed the whole world, but also quoted leaders 

of other faiths. Similarly, a new synodal process and apostolic exhortation could include religious 

leaders and reference texts of other faiths to highlight the importance of ecumenical and inter-

religious peacebuilding, as well as the distinctive contributions of other faiths and secular 

specialists. At the same time, a synod could emphasize what is distinctive about Catholic 

approaches to peacebuilding. 

Given the prevalence of conflicts with a religious dimension, a synod would have to reiterate 

the frequent denunciations of the new holy wars—religious violence and religious nationalism—

by religious leaders. It would also have to address the prevailing secularist paradigm, which tends 

to view religion mainly as a source of conflict and division and thus seeks to remove it from the 

public square and marginalize and privatize it. The synod would make the case that strengthening 

religious peacebuilding is an obvious antidote to both contemporary holy warriors and the 

secularist paradigm. It could welcome scholars and policymakers who are enhancing their literacy 

on religion, conflict, and peace. It could make the case that marginalizing religion impoverishes 

peacebuilding because elements of peacebuilding, such as forgiveness, reconciliation, and 

solidarity, either are not prominent in secular policy discourse or become rather “thin” when 

separated from their religious and moral roots.22 

“Thick” religious contributions to peacebuilding require greater attention to single-identity 

peacebuilding. Developing common ground and common action on conflict and peacebuilding is 

essential, but the quality of ecumenical and interreligious peacebuilding is a function of the quality 

of intra-denominational and intra-religious peacebuilding. According to Scott Appleby, the Church 

relies on a “distinctive set of teachings, practices, sensibilities, and institutional resources” that 

might not be “exclusive” to Catholicism but that come together in a special way in Catholic 

peacebuilding.23 The process of holding a world-wide synod would, itself, exemplify one 

distinctively Catholic dimension: the Church’s “ubiquitous presence.” As John Paul Lederach, a 

prominent Mennonite peacebuilder, points out, this presence gives the Church a “unique if not 

unprecedented presence in the landscape of the conflict.” Especially in majority Catholic countries 

like Colombia, he adds, few religious or secular institutions have the infrastructure or ecclesiology 

that “so neatly aligns with the multilevel and multifaceted demands of peacebuilding.”24 A second 



135  Powers 
 

distinctive aspect of Catholic peacebuilding is the role of the Catholic social imaginary, including 

ritual, sacrament, and spirituality. Schreiter argues that a secular bias in peacebuilding has mostly 

ignored the role of ritual in conflict prevention, transformation, and reconciliation.25 A synod 

could urge the Catholic community to revitalize and deepen its understanding of the distinctive 

role of sacraments in Catholicism and how they offer deep spiritual grounding for the Church’s 

peacebuilding. 

In addressing what is distinctive about Catholic peacebuilding, a synod would have to avoid 

any hint of triumphalism, exclusivity, or parochialism. But further plumbing of the spiritual, 

theological, and pastoral depths of Catholic peacebuilding is essential if the peacebuilding vocation 

is to be an animating feature of lived Catholicism and if the Church is to make her most authentic 

and fullest contribution to the world’s wider peacebuilding project. 

 

Peacebuilding, nonviolence and the just war tradition 

Finally, as noted earlier, a synod need not dwell on the well-trod debate over just war and 

nonviolence, nor need it take a page out of the Mennonite Confession of Faith, discard the just war 

tradition, and embrace nonviolence as the sole Christian option. Instead, it could expand on and 

reinforce the growing importance of nonviolence in Catholic teaching, explicitly reject permissive 

approaches to the just war tradition in favor of a highly-restrictive one, and elaborate on the 

inherent complementarity of nonviolence, restrictive just war, and a broader theology and ethics 

of peacebuilding. 

Since Vatican II and especially since the end of the Cold War, nonviolence has received greater 

emphasis and legitimacy in official Church teaching. Papal and other statements are replete with 

condemnations of the “savagery” and “scourge” of war, descriptions of war as “an adventure 

without return” and a “defeat for humanity,” and hortatory appeals, such as “war never again” and 

“war is not the answer.”26 The experience of total war in the twentieth century, the threat of a 

nuclear holocaust, and the fact that civilians have increasingly been the main victims of war have 

led the Church to be deeply skeptical of the ability of modern war to meet just war criteria. At the 

same time, successful nonviolent change, from the demise of Marcos in the Philippines to the 

mostly peaceful dissolution of the Soviet bloc, has demonstrated the efficacy of nonviolence.27 

Nevertheless, nonviolence has been considered an option for individuals, not governments. A 

synod could call on the Catholic community to give much greater attention to nonviolence as a 



Our Vocation Is Peacebuilding  136 
 

core element of its identity. Without rejecting the just war tradition, a synod could call on 

governments to take their obligation to develop institutions, strategies, and means of nonviolent 

conflict resolution at least as seriously as they take their responsibility to develop their capacity to 

defend the common good through military means.28 Such clarity about the obligation of 

governments to pursue nonviolent means of conflict resolution would significantly raise the 

threshold for the resort to force. It also would reinforce the Church’s long-term vision of 

strengthening international law, international institutions, and means of conflict transformation to 

the point that war will become obsolete. 

While highlighting nonviolence, a synod could at the same time emphasize that the Church’s 

restrictive approach to just war is not an impediment to peacebuilding, but is an element of it.29 A 

permissive approach to just war too readily justifies war and is prone to misuse, but the Church’s 

restrictive just war approach, when followed, places severe constraints on the use of force. It helps 

delegitimize the holy war claims of religious terrorists or religious nationalists. It is a form of 

conflict prevention when jus ad bellum criteria are used to oppose military interventions, as was 

done by the Vatican, episcopal conferences, and pacifists, too, in opposing U.S. intervention in 

Iraq in 2003. Finally, jus in bello norms are elements of peacebuilding insofar as they seek to limit 

the civilian suffering that fuels cycles of violence and makes it much more difficult both to end 

conflicts and to promote post-conflict reconciliation. 

Last but not least, a synod could elaborate on the ways in which nonviolence, restrictive just 

war, and a broader theology and ethics of peacebuilding complement each other. Neither 

nonviolence nor restrictive just war nor even a combination of the two is capacious enough to 

address the most difficult peacebuilding challenges. Theories of nonviolence and just war 

contribute little to post-conflict nation-building, trauma healing, and reconciliation in countries 

torn asunder by civil wars. Both nonviolence and just war can ground condemnations of religious 

violence and religious nationalism, but much more is needed to address the roots of terrorism, 

conflicting claims of self-determination, and deeply-rooted sectarianism. Moreover, theories of 

nonviolence and just war offer little guidance for understanding the relationship between the ethics 

of intervention and the ethics of exit. For example, while it may have been immoral for the U.S. 

to intervene in Iraq in 2003, it was not immoral for the U.S. to stay given the new obligations it 

incurred as the de jure and then de facto sovereign. In sum, the credibility and validity of both 

nonviolence and restrictive just war depend on whether they are tied to an ethics of peacebuilding 



137  Powers 
 

that can address these and other broader challenges of war and peace. 

 

Conclusion 

The Catholic community around the world is doing courageous work for peace in some of the 

world’s most war-torn places, but this work tends to be unheralded, unknown, and under-

analyzed—and mostly operates on the margins of Church life. A synod on the vocation of 

peacebuilding would bring new visibility to this peacebuilding and would seek to move 

peacebuilding from the margins to the center. A synod process with the vocation of peacebuilding 

as its animating principle, a practical theology of peacebuilding as its method, and a commitment 

to exploring the complementarity of nonviolence, restrictive just war, and an ethics of 

peacebuilding would contribute to what Scott Appleby calls “a conceptually coherent, 

theologically sophisticated and spiritually enlivening” approach to Catholic peacebuilding that can 

begin to match the sophistication of Catholic thinking on the ethics of war and peace.30 A synod 

also would enable the Catholic community to move closer to becoming a peacebuilding Church in 

an authentically Catholic way.
