In Mr Fitnah's thread concerning Koranic exhortations to violence (contested) it occurred to me that a good look at the three Abrahamic religions might be useful. As I said in that thread my knowledge is scant, but I'll say what I think I know and wait for more information. As I understand it Abraham, a Hebrew, was visited by God and possibly began the first (apparently there's some thought that there were earlier ideas of monotheism but not sure) monotheistic religion based on revelations from God. That became Judaism. Then Yeshua, who was called Jesus Christ, the Anointed One, came along as an Aramaic-speaking Jew and preached and drew followers. In His name Christianity developed from its Judaic roots. Much later, 7th Century (?) CE, Mohammed was visited by the Archangel Gabriel who revealed the Koran to the Prophet. Allah/God was a bit annoyed that the earlier two Abrahamic religions which worshipped Him had gone off the rails a bit and the Prophet had revealed to him the Koran so that he could begin to set people right. The point I made in Mr F's thread was that adherents of the three religions are essentially worshipping the same God. There are major doctrinal differences though. But the object of veneration is the same God.
