The Antinomian heresy rejects the 10 commandments as not pertinent today..
The Anglo-Israeli or supercessionist theory rejects Israel's proper place in Christian roots and history.
The Antinomians of today want to consider themselves save Christians who are welcome to sin all they wish, relying upon grace to save them.. Wrong! see (Romans 6:1,2)
The Mormons and Herbert W Armstrong's church, and his successors at "The world Tomorrow", think the people in Israel today are not the descendants of the original 12 tribes. They believe those tribes migrated first to the UK, and a good portion of them migrated to America..
..Bet some folks of English, Irish, Welsh or Scottish extraction, didn't know they are actually Jewish !
Of course Jesus was a Jew..he was circumcised on the 8th day, dedicated as a Jew, and his parents raised him as a Jew. They made the regular pilgrimages to the temple in Jerusalem..and as Jewish custom, at 12 years of age , he disputed with the priests and scholars in the temple. He observed the passover and travelled into Jerusalem for it, eve though He knew He would be crucified during that week.
He could not have been a Christian, simply because the term wasn't even codified before He was crucified.
Just as th ePuritans didn't want to leave the Anglican church, but to "purify" it, and Martin Luther posted his 95 thesis on the door of the Wittenberg cathedral in hopes of reforming the RC Church..Jesus came to the Jews, in an effort to straighten them out..
“Think not that I have come to abolish the Torah and the prophets; I have come not to abolish them but to fulfill them,” he says in Matthew 5:17. However, when the bulk of the Jews refused to listen, He then reached out to the gentiles.
Call it what you wish..Christianity is the extension (New Covenant) of Judaism, which the Jews just haven't latched onto yet.
