Ruddy isn't going to stop until he convinces us Christians that we are really Jews. The guy is demented.
Christianty was created by Jews who mixed Judaism with the Roman belief of Mithraism to make it more palatable. It is based on the life of a Jew in occupied Judeah who in essence Christians believe to be the Messiah of the Old Testament. Egyptians, Romans, Greeks, etc. always considered their leaders to be "sons of God." It is not new concept in history.
The NT is an addition to the OT. You cannot be a Christian if you don't believe in the OT.
That's true. Sherri and monte don't believe in the Old Testament (three-quarters of their Bible), besides knowing nothing of their contents.
Certain tenants of the Old Testament run counter to Christian teachings, that's why it can't be accepted without critical review. The most basic example you will get in Catechism class is:
"You have heard that it was said, 'AN EYE FOR AN EYE, AND A TOOTH FOR A TOOTH.'
39"But I say to you, do not resist an evil person; but whoever slaps you on your right cheek, turn the other to him also."
Matthew 5:38
In any case, you will not convince Christians they are Jews.
