Need proof that the New Testament promotes Torah?

Here is just one example!

Acts15: 12 Then the whole assembly kept still as they listened to Bar-Nabba and Sha'ul tell what signs and miracles God had done through them among the Gentiles. 13 Ya'akov broke the silence to reply. "Brothers," he said, "hear what I have to say.

14 Shim'on has told in detail what God did when he first began to show his concern for taking from among the Goyim a people to bear his name. 15 And the words of the Prophets are in complete harmony with this for it is written,

16 '"After this, I will return; and I will rebuild the fallen tent of David. I will rebuild its ruins, I will restore it, 17 so that the rest of mankind may seek the Lord, that is, all the Goyim who have been called by my name," 18 says ADONAI, who is doing these things.' All this has been known for ages.

19 "Therefore, my opinion is that we should not put obstacles in the way of the Goyim who are turning to God. 20 Instead, we should write them a letter telling them to abstain from things polluted by idols, from fornication, from what is strangled and from blood. 21 For from the earliest times, Moshe has had in every city those who proclaim him, with his words being read in the synagogues every Shabbat." (CJB)

This is actually a fulfillment of Isaiah 56:1-9 because, here we see Gentile converts observing Shabbat and learning Torah as one body along with Jews! Unfortunately, not long afterward, Marcion (whom Polycarp (referred to as “the firstborn of the devil”) built the first all-Gentile church to promote anti-Torah sentiment. (Of course, no one noticed because it all “sounded good” so people blindly followed...

Marcion's services were held on Sunday which blended with Zeus (the sun god) culture, based in Hellenism – which was in total opposition to our Jewish Messiah

By the way, Marcion was the one who coined the words “Old - New Testament” by doing his very best to warn Gentiles away from Torah and “the God of the "Old Testament.” He also invented theologies known as replacement, dispensational, supercessionism, etc. - none of which lined up with YHWH's Word.
