The teaching of the NT is Torah, in every case. Too bad that some hate Yehova’s loving Torah so much that they will stretch errors to escape his commandments.
The whole NT is about teaching gentiles how to follow Torah.
Jeremiah 16:19
O LORD, my strength, and my fortress, and my refuge in the day of affliction, the Gentiles shall come unto thee from the ends of the earth, and shall say, Surely our fathers have inherited lies, vanity, and things wherein there is no profit.
Time is short; best to study and learn, rather than speaking foolishly. .
The teaching of the Old Testament is Christ, in every case.
"But before faith came, we were kept under the Law, as under a garrison, and shut up unto [m]that faith, which should afterward be revealed. Wherefore the Law was our schoolmaster to bring us to Christ, that we might be made righteous by faith. But after that faith is come, we are no longer under a schoolmaster."
Read the Old Testament through the lens of New, not the New Testament through the lens of the Old.
He shouldn’t be arguing with you, in any case
Wrong.
The NT is about teaching people to follow CHRIST.
People cannot live up to God's standards and be holy as God is holy. Not possible. Get out of that cult you are following.
