Pulitzer Prize winner Wills spent five years at a Jesuit seminary and nearly became a priest, so the provocative questions he raises in his latest book are grounded in serious study. Wills points out that Christianity initially had no priests and in fact opposed the very idea; the anonymous Letter to the Hebrews, added late to the New Testament canon, brought in the priesthood and other now-key concepts, e.g., the real presence in the Eucharist. So why do we need priests? Even as he acknowledges that the priesthood wont wither and die, Wills ponders that question. Clearly a thought-provoker destined to inspire debate.
