I've asked that question myself for over a decade, and I've never received an answer. Have you noticed that the people who tell us to read the "Early Church Fathers" demonstrate little familiarity with the works of the Earliest Church Fathers, i.e. the New Testament writings of the Apostles?
Yes....if they read the ECFs they would find the ECFs are all over the board on issues near and dear to catholicism. A whole lot of contradictions.
