A masterful and highly accessible study of how Vatican II's teachings on collegiality, or how power and responsibility were to be shared between the Pope and the college of bishops within the Catholic Church, have either been side-tracked or not yet come to fruition. Against the background of ‘silencings' by the Vatican of Irish priests, and the results of the Association of Catholic Priests recent survey of Catholic attitudes, this thoughtful and balanced assessment is very timely. Written by a highly respected public figure who served as Ireland's President for 14 years, Quo Vadis is a timely contribution to the ongoing debate within the global church on where we are going.
