The great majority of the Church is still under the sway of Augustinian influence. It was Augustine of Hippo who made the biggest impact on Christian doctrine, and while he had a grasp of soteriology, the study of salvation and sanctification, he was, in my opinion, a terrible theologian when it came to pretty much every other subject.
I know this seems harsh, but he was the leading influence on abandoning the clear understanding of the early church through the first generations of church fathers concerning the incident in Genesis 6. He popularized the notion that is still taught in cemetaries...I mean seminaries, today. That it was the righteous line of Seth that intermingled with the wicked daughters of Cain that produced the Nephilim. That's absoultely not what the text says! You have to do more hermeneutical gymnastics than Nadia Comenici and Mary Lou Retton ever did combined to reach that conclusion. Augustine didn't like the idea, so he came up with an interpretation. That's eisegesis, not exegesis.
