Catholicism of all things

Of the branches of Christianity, and perhaps of all religions, Catholicism has the most developed theology, the most rigorous set of justifications for belief, the longest intellectual tradition and tries the hardest to be convivial with reason. Other branches and other religions would be a lot more surprising (unless you're counting Quakers and Unitarians, for which religion has very little to do with "belief" as we understand it here.) Especially for a self-described virtue ethicist.
