I would read St. Irenaeus in his Adversus Haereses. I would start with the actual people who were there around that time rather than 21st century interpretations based on translations.
You would start with men, while we start with the Bible.
I’d ignore this rot from shallow Bible Christians. Apparently, until the Reformation of 1517, all saints, martyrs, the early Church fathers, Catholic theologians, those who assembled the written texts and declared it to be the true written Word of God in AD 382 and since then even those eminent Protestant theologians who converted to Catholicism, all got it wrong.
And oh, all of the following got it wrong too.

Bible Christians believe they can each offer us “their” own interpretation of God’s word, and instead the authority given to Peter and his successors is up for grabs. Just look around and see the mudslides of heretical beliefs that have washed ashore as flotsam and jetsam since the arch progenitors of this heresy.
This crowd believes in “Christianity Lite,” and so they’d rush to any corner street blogger to capture their streams of interpretations. Jim Jones and David Koresh did the same thing.
Don’t waste your time arguing in shallow waters. Bible Christians drown in deep theological waters.
