“Wow! I confess I thought this was accepted Christian teaching as well. I understand the fear and denial of Jewish theology, but did not realize it extended to actual Jewish history.”
Your response has nothing whatever to do with the things discussed. So, are people magically being born circumcised part of “actual Jewish history?” Is Psalm 110 about the one whom David called “my Lord,” and “my LORD said unto my Lord” or not? And why should we believe Jewish fables written in the first century AD and after that, when they of themselves are very absurd and make false claims about the topics of Psalms?
In Hebrew, the Psalm 110 phrase actually translates “GOD said to my lord...” It first uses the four letter name of God who addresses ‘my master’, a completely different word and concept to any familiar with English usage of a couple generations ago. That second ‘lord’ is the Hebrew word ‘adon’ still used where we might say ‘mister’ in English.
This is pretty basic stuff.
