Heavens no! Paul said the Gentiles are spiritually circumcised because they have faith in God as Abraham did well before the law of Moses was given.
Romans 2:26
“So, if a man who is uncircumcised keeps the precepts of the law, will not his uncircumcision be regarded as circumcision?”
That verse notably does notably does not state that a Gentile who has faith will be regarded as circumcision, but one who keeps the law, though the Bible often conflated the two, such as in Revelation 14:12, those who kept faith in Jesus are the same as those who kept God’s commandments. It is contradictory for someone to think that we should have faith in God, but not in His instructions.
God’s way is the way to know Him by being in His likeness through being a doer of His character traits, such as in Genesis 18:19, God knew Abraham that he would teach his children and those of his household to walk in His way by being a doer of righteousness and justice that the Lord might bring to him all that He promised. In Genesis 26:4-5, God will multiply Abraham’s children as the stars in the heavens, to his children He will give all of these lands, and through his children all of the nations of the earth will be blessed because he heard God’s voice and guarded His charge, commandments, statues, and laws. In Deuteronomy 30:16, if the children of Abraham will love God with all of their hearts by walking in God’s way in obedience to His commandments, statues, and laws, then they will live and multiply and God will bless them in the land that they go to possess. So the promise was made to Abraham and brought about because he walked in God’s way in obedience to His law, he taught his children and those of his household to do that, and because they did that. Moreover, in Exodus 33:13, Moses wanted God to be gracious to him by teaching him to walk in His way that he and Israel might know Him. So both Abraham and Moses taught how to know God by walking in His way in obedience to His law.
God commanded physical circumcision for Jews as part of the sacrificial laws that He intended to keep their culture separate until it provided Messiah for the salvation of all humanity potentially, after which such laws became optional.
In 1 Peter 1:16, we are told to be holy for God is holy, which is a quote from Leviticus where God was giving instructions for how to do that. In 1 Peter 2:9-10, Gentiles are included as part of God’s chosen people, a holy nation, a royal priesthood, and a treasure of God’s own possession, which are terms used to describe Israel (Deuteronomy 7:6), so Gentiles also have the delight of getting to obey the instructions that God had given for how to fulfill those roles and holiness is not just for Jews. It would be contradictory for a Gentile to want to live as part of a holy nation while not wanting to follow God’s instructions for how to do that. The only way that we should cease to follow God’s instructions for how be holy as He is holy would be if God were to cease to be holy, and the same goes for God’s other instructions for how to be in His likeness by being a doer of His character traits.
Jesus saves is from our sin (Matthew 1:21) and sin is the transgression of God’s law, so Jesus graciously teaching us to be a doer of it is intrinsically the way that he is giving us his gift of saving us from not being a doer of it. If someone doesn’t want to be a doer of God’s law, they they also do not want God’s gift of salvation.
