Stephen Bullivant on the Mass Exodus of Catholics: UPDATED

I've been reading and enjoying the many insights in Stephen Bullivant's new book, Mass Exodus: Catholic Disaffiliation in Britain and American Since Vatican II (Oxford University Press, 2019), 336pp. It is the kind of book that should be read by everybody in the Catholic Church, but also anyone interested in the sociology of religion. I have an interview with the author to be published soon, and will essay more thoughts on the book later. About it the publisher tells us this:

In 1962, Pope John XXIII opened the Second Vatican Council with the prophecy that 'a new day is dawning on the Church, bathing her in radiant splendour'. Desiring 'to impart an ever increasing vigour to the Christian life of the faithful', the Council Fathers devoted particular attention to the laity, and set in motion a series of sweeping reforms. The most significant of these centred on refashioning the Church's liturgy--'the source and summit of the Christian life'--in order to make 'it pastorally efficacious to the fullest degree'.

Over fifty years on, however, the statistics speak for themselves. In America, only 15% of cradle Catholics say that they attend Mass on a weekly basis; meanwhile, 35% no longer even tick the 'Catholic box' on surveys. In Britain, the signs are direr still. Of those raised Catholic, just 13% still attend Mass weekly, and 37% say they have 'no religion'. But is this all the fault of Vatican II, and its runaway reforms? Or are wider social, cultural, and moral forces primarily to blame? Catholicism is not the only Christian group to have suffered serious declines since the 1960s. If anything Catholics exhibit higher church attendance, and better retention, than most Protestant churches do. If Vatican II is not the cause of Catholicism's crisis, might it instead be the secret to its comparative success? 

Mass Exodus is the first serious historical and sociological study of Catholic lapsation and disaffiliation. Drawing on a wide range of theological, historical, and sociological sources, Stephen Bullivant offers a comparative study of secularization across two famously contrasting religious cultures: Britain and the USA.

UPDATE: Here is the interview I did with Stephen for Catholic World Report.
