To the best of my knowledge they believed in 7 sacraments, sacerdotal grace of holy orders, praying to the saints, and that the bishop of Rome was the successor of Peter and was the Vicar of Christ over the Church universal....so I probably would call them papists. I think the Church of Rome was corrupt almost from the beginning and truely advanced it's corruption under the Emperor Constantine.Of course they are... Was the Catholic Church pagan in the 4-5th centuries? Did they have popes? I don't think that had started yet, and if it had it was just a bishop (nothing like what you see in a pope today). The Catholic Church in Augustine's time was not heretical. It was THE VISIBLE CHURCH.
Seems like you need to study church history a little more or at least understand that all pre-1000AD Catholics aren't all that bad...
Are you going to call all of the Church Fathers 'papists'? Anselm, Thomas Aquinas? (They are praised by RC).
I have these books at home in regards to views of the ECFs. It seems most of them were very diverse and very Catholic.
