Garry has come full circle from the 1960s when he defended National Review's and Bill Buckley's attack on the encyclical Mater et Magistra as a socialist document in Catholic garb (thereby rejecting Rerum Novarum and its progeny which are basic to Catholic social teaching) to now attacking the Vatican for not being foolishly liberal on Church matters as is Wills.
There is one consistency that must be noted. Garry Wills, in his long and sorry career of posing as a Catholic, has never been consistent with the teachings of the Church and has never been a practitioner of humble humility before legitimate Church authority. Humility would certainly be warranted on his part as his persistent rebellions are not.
Sleazy, too ;)
