Four of his thirteen published books deal with Catholic Church reform. His latest books include A Church in Search of Itself: Benedict XVI and the Battle for the Future and "Cardinal Mahony: A Novel." A new version of his 1970 best seller, R.F.K.

Kaiser's speech in Ireland on August 19, 2010, at the Humbert Summer School, entitled "Catholic Church Reform: No More Thrones," called for Irish Catholics to boldly initiate an ecclesiastical revolution through which they would remove secretive hierarchy, take back their cathedrals, and elect their own bishops.
