Peter & Paul were Jewish who followed Messiah in the keeping and teaching of Torah. The doctrine of Christendom rejects Torah.
ok, so you say. Paul says in 1 cor about himself "though not being myself under the Law," and later on contradicts the Torah's teaching on circumscision.
What you have outlined is the teachings of the Ebionites who though they accepted Jesus as the Messiah, rejected the teachings of Paul
in fact they rejected Paul as an apostate. They moved to the Hejaz region of Arabia and these are the false teachings that influenced islam.
The Talmud is usually considered part of the Torah, is it not?
“The doctrine of Christendom rejects Torah.”
Maybe your doctrine does.
