St. Jerome, Helvetius, and Mary’s Perpetual Virginity - Quick Question
Karl Keating has cited someone approaching St. Jerome in the early Church and asking St. Jerome to respond to the heretic Helvetius who was denying the Perpetual Virginity of Mary at the time.
St. Jerome called it a "novel, wicked, and daring affront to the faith of the whole world."
St. Jerome later wrote a direct response to Helvetius.
My question is, TO WHOM did St. Jerome say Helvetius’ error is a "novel, wicked, and daring affront to the faith of the whole world."?
I’m not doubting Karl Keating’s quote source—he is an excellent apologist. I just want to read more from the original source.
I read and re-read St. Jerome’s letter to Helvetius and it is NOT in there. So WHERE did that quote come from?
Any information and links if possible would be helpful.
(moderator, if you think a different thread forum other than Scripture Apologetics would get me an answer faster, please move it to such a thread forum. I just thought the Catholic Apologists would be able to answer this query rapidly)
