Now do read the Bible -- Galatians 5:2-3 2Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing.
3For I testify again to every man that is circumcised, that he is a debtor to do the whole law.
4Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.
and 1 Cor 7:18 18Is any man called being circumcised? let him not become uncircumcised. Is any called in uncircumcision? let him not be circumcised.
Please do read the Bible and realise that your statement Paul were Jewish who followed Messiah in the keeping and teaching of Torah is wrong -- he on the matter of circumcision taught against the Torah.
John 11:49 And one of them, Caiaphas, being high priest that year, said to them, You know nothing at all, 50 nor do you consider that it is expedient for us that one man should die for the people, and not that the whole nation should perish. 51 Now this he did not say on his own authority; but being high priest that year he prophesied that Jesus would die for the nation(Judah), 52 and not for that nation only, but also that He would gather together in one the children of God who were scattered abroad
James(Jacob) 1:1 James, a bondservant of God and of the Lord Jesus Christ,To the twelve tribes which are scattered abroad: Greetings
Eph 2:11 Therefore remember that you, once Gentiles(goy) in the fleshwho are called Uncircumcision by what is called the Circumcision made in the flesh by hands 12 that at that time you were without Christ, being aliens(ger= estranged) from the commonwealth of Israel and strangers(goy) from the covenants of promise ... 19 Now, therefore, you are no longer strangers(goy) and foreigners(goy), but fellow citizens(ger) with the saints and members of the household of God
Mt 10:5 These twelve Jesus sent out and commanded them, saying: Do not go into the way of the Gentiles, and do not enter a city of the Samaritans. 6 But go rather to the lost sheep of the house of Israel. 7 And as you go, preach, saying, The kingdom of heaven is at hand.
Mt 15:24 But He answered and said, I was not sent except to the lost sheep of the house of Israel.
John 7:35 Then the Jews said among themselves, Where does He intend to go that we shall not find Him? Does He intend to go to the Dispersion among the Greeks and teach the Greeks?
1 Peter:1 To the pilgrims of the Dispersion(ger) in Pontus, Galatia, Cappadocia, Asia, and Bithynia, 2 elect(bachiyr=chosen like Moses) according to the foreknowledge of God the Father
