I'm sorry you have not read Galations 5:2-4
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 Is any man called being circumcised? let him not become uncircumcised. Is any called in uncircumcision? let him not be circumcised --> so Paul is saying not to follow the Torah's teaching on circumcision, hence your statement is incorrect.
1Co 7:19 The circumcision is naught, and the uncircumcision is naught, but the guarding of the commands of Elohim does matter! [Footnote: 1Rom. 2:26-29] 20 Let each one remain in the same calling in which he was called
Rom 2:26 So, if an uncircumcised one watches over the righteousnesses of the Torah, shall not his uncircumcision be reckoned as circumcision?
27 And the uncircumcised by nature, who perfects the Torah, shall judge you who notwithstanding letter and circumcision are a transgressor of the Torah!
Deu 10:12 And now, Yisra'l, what is יהוה your Elohim asking of you, but to fear יהוה your Elohim, to walk in all His ways and to love Him, and to serve יהוה your Elohim with all your heart and with all your being,
13 to guard the commands of יהוה and His laws which I command you today for your good?
14 See, the heavens and the heaven of heavens belong to יהוה your Elohim, also the earth with all that is in it.
15 יהוה delighted only in your fathers, to love them. And He chose their seed after them, you above all peoples, as it is today.
16 And you shall circumcise the foreskin of your heart, and harden your neck no more.
Deu 30:6 And יהוה your Elohim shall circumcise your heart and the heart of your seed, to love יהוה your Elohim with all your heart and with all your being, so that you might live,
7 and יהוה your Elohim shall put all these curses on your enemies and on those who hate you, who persecuted you.
8 And you shall turn back and obey the voice of יהוה and do all His commands which I command you today.
9 And יהוה your Elohim shall make you have excess in all the work of your hand, in the fruit of your body, and in the fruit of your livestock, and in the fruit of your ground for good. For יהוה turns back to rejoice over you for good as He rejoiced over your fathers,
10 if you obey the voice of יהוה your Elohim, to guard His commands and His laws which are written in this Book of the Torah, if you turn back to יהוה your Elohim with all your heart and with all your being.
What? Circumcision of the heart is nothing new? What? Paul telling us that we are Jews because we have received circumcision of the heart and the church teaches that Torah is ONLY for the Jews? I'll be interested to see how you reconcile this one.
