Ryan’s go-to move has always been to keep the argument strictly on Scripture, where his own interpretation becomes the controlling authority. But asserting an interpretation DOES NOT establish it.
If his reading were the obvious Christian understanding of Scripture, we should expect to find it in the historic Church. St. Ephrem (Nisibene Hymns 27:8), St. Augustine (De natura et gratia 36.42), and even Luther all agreed.
So even if we grant Ryan his "inference" (which is massively incorrect but for the sake of argument) we are still left with this fact: for more than 1,800 years, no major Christian thinker interpreted the text the way he does.
I asked this Catholic: If you simply read the Bible from Genesis to Revelation, would you come away believing that Mary was sinlessly perfect?
This is what he said.
