You have never read the Early Church Fathers then? Was St. Bede, St. Hillary, St. Augustine, St. John Damascens, St Athanasius, were they all pagans also?
So when was Christianity pure from evil pagan influences? When did it change? Did your pastor tell you it was when the first Christian king came to power? Or was it earlier? How is it that the Church, which was entrusted with the care of the sacred deposit of Faith and the guidance of the Holy Spirit went astray so quickly? Did Jesus come to save only one generation?
And not one of these ECFs writings were ever declared Scripture by the NT Church. Not one.
Further, when they are opposed to one of Rome's other doctrines, do you still cite the ECF or just say they were in error because it doesn't line up with Rome's beliefs?
By not adhering to Scripture as the sole source of doctrine you're having to jump between which ECF you want to believe on the various doctrines of Rome.
Additionally the door is left open for any new false doctrine to be introduced such as the Fifth Marian Dogma currently under consideration.
I have.

Please note the heresy that arrived before the death of John the Apostle, as delineated in Revelation.
