they do more than rewrite the Bible....
Wasn't Abraham the father of the Jews? And due to his faithfulness in willing to sacrifice Isaac, God promised that the covenant would pass through to Isaac and not Ishmael? Genesis records that Isaac is Abraham's son, his only son on several occasions.
Abraham’s first son, thru adultery, was Ishmael - father of the Islamic line.
Abraham’s first son thru marriage was Isaac - father of the Jewish (and hence Cheistian) line.
Question is whether the bastard is disqualified of ancestral headship.
And hence confusion reigns.
Yes, and what I’ve heard and see some mention of from Google right now though I don’t have time to read more is that they say it was Ishmael who was the intended sacrifice, not Isaac. I also saw that two places where the Lord called Himself the God of Abraham, Isaac and Jacob were in revealing Himself to Moses in the burning bush, and in the New Testament in Acts 3:13. The Muslims worship a false god, a corrupted idea of the true God.
