Book excerpt: It is fairly clear that, while Rome continues to teach as if its authority were unchanged from the days before Vatican II (1962-65), the majority of Catholics - within the first-world church, at least - take a far more independent line, and increasingly understand themselves (rather than the church) as the final arbiter of decision-making, especially on ethical questions. This collection of essays explores the historical background and present ecclesial situation, explaining the dramatic shift in attitude on the part of contemporary Catholics in the U.S. and Europe.
