CharlesII, this is an excellent primer for "beginners", and also a good review.
John Stadtmiller speaks fearlessly on his radio network, RBN, although I'm a bit new to it. I do not know if he is Catholic.
"The declared enemies of God and His Church, heretics and schismatics, must be criticized as much as possible, as long as truth is not denied. It is a work of charity to shout: 'Here is the wolf!' when it enters the flock or anywhere else."
--St. Francis de Sales
John Stadtmiller mentioned he attended Catholic School in the 1960's. He grew up in a
Catholic Family. His family are mostly from Italy. What I can gather after some years
of daily listening to John, he is a non-practicing Catholic in his adult life. Mostly because
of the radical changes of beliefs pushed by the nuns in his catholic school he was attending.
