Revisionist tripe. Read the man’s own writings (St. Patrick’s)- he clearly ordained priests, and confirmed; he says so himself. I don’t think the modern Baptists would have approved! He also encouraged monasticism and celibacy for his monks and nuns (also directly from Patrick’s writings, not someone’s cherry picked versions). I have the book and read it myself - St. Patrick was a man of the sacraments.
People deny the holocaust, too, even in the face of actual evidence for it; in other words, anyone can revise history when they are trying to prove an agenda: - it is up to us to go to the root sources, in this case, Patrick’s own Confessions.
Go to Ireland - the monasteries there founded by St. Patrick and his followers are WITHOUT A DOUBT Catholic.
