142 The American Journal of [slamic Social Sciences 19:4 Roman Catholics and Shi'i Musli ms: Prayer, Passion, and Politics James A. Bill and John Alden Williams Chapel Hill: University of North Carolina Press, 2002. 166 pages. Comparing Roman Catholicism and Twelver Shi'i Islam suggests itself for several reasons: the parallel passions of Jesus Christ and Prophet Muham­ mad's grandson Husayn; the suffering of and devotion of their mothers, Mary and Fatimah; and perhaps most prominently in recent years, the powerful hierarchies of authority within each faith, headed by the Pope on the Catholic side and by several leading jurists (mljjtahidun) who bear the title of legal authority for laymen ( marji>al-taqlid) on the Shi'i side. In fact, the papacy is frequently mentioned in contemporary debates about the marji> al-taqlid's Book Reviews 145 Sunni Islamic societies and the various Protestant churches, but they have been influential nevertheless. In Roman Catholics and Shi'i Muslims, Bill and Williams have taken an important step beyond this negative and superficial approach and pro­ duced a sympathetic and even-handed portrayal of both Roman Catholicism and Twelver Shi 'i Islam. In adopting this sympathetic approach, however, they have missed an important opportunity for another comparative chapter. As a by-product of clerical power, both Catholic and Shi'i societies have developed rich anti-clerical folk traditions, involving myriad jokes and anecdotes about lecherous, greedy clerics, whether they be priests in France or mullahs in Iran.
