Recently I commented about the fact that—contrary to those who want to say that Vatican II was supposedly a “liberal” council in some odd way or other—it is no novelty to describe Protestants as “separated brethren.” Now Taylor Marshall at Called to Communion has trumped me. He has a post there showing that St Augustine called the Donatist heretics his brothers. How could he do this? Because of their valid baptisms. In the same way, we may do the same for our Protestant brothers in Christ, just as Vatican II affirms.
