I'll even break it down in two parts for you.
Heb 8:7
7 For if that first covenant had been faultless, then no place would have been sought for a second.
(NKJ)
Heb 10:1

(NKJ)
Col 2:11-14
11 In Him you were also circumcised with the circumcision made without hands, by putting off the body of the sins of the flesh, by the circumcision of Christ,
12 buried with Him in baptism, in which you also were raised with Him through faith in the working of God, who raised Him from the dead.
13 And you, being dead in your trespasses and the uncircumcision of your flesh, He has made alive together with Him, having forgiven you all trespasses,
14 having wiped out the handwriting of requirements that was against us, which was contrary to us. And He has taken it out of the way, having nailed it to the cross.

Gal 5:1-4
1 Stand fast therefore in the liberty by which Christ has made us free, and do not be entangled again with a yoke of bondage.
2 Indeed I, Paul, say to you that if you become circumcised, Christ will profit you nothing.
3 And I testify again to every man who becomes circumcised that he is a debtor to keep the whole law.
4 You have become estranged from Christ, you who attempt to be justified by law; you have fallen from grace.
(NKJ)
Luke 16:13
13 "No servant can serve two masters; for either he will hate the one and love the other, or else he will be loyal to the one and despise the other. You cannot serve God and mammon."

(NKJ)
Rom 7:1-4
1 Or do you not know, brethren (for I speak to those who know the law), that the law has dominion over a man as long as he lives?
2 For the woman who has a husband is bound by the law to her husband as long as he lives. But if the husband dies, she is released from the law of her husband.
3 So then if, while her husband lives, she marries another man, she will be called an adulteress; but if her husband dies, she is free from that law, so that she is no adulteress, though she has married another man.
4 Therefore, my brethren, you also have become dead to the law through the body of Christ, that you may be married to another-- to Him who was raised from the dead, that we should bear fruit to God.
(NKJ)

21 "but they have been informed about you that you teach all the Jews who are among the Gentiles to forsake Moses, saying that they ought not to circumcise their children nor to walk according to the customs.

xxx Jesus nailed the old testament to the cross. If you have nailed the old testament to your cross, you are in Christianity.
Jesus changed the priesthood,He changed the Law, He annulled the commandments, and He made the covenant obsolete.
Heb 7:11-12
11 Therefore, if perfection were through the Levitical priesthood (for under it the people received the law), what further need was there that another priest should rise according to the order of Melchizedek, and not be called according to the order of Aaron?
12 For the priesthood being changed, of necessity there is also a change of the law.
(NKJ)
Heb 7:18
18 For on the one hand there is an annulling of the former commandment because of its weakness and unprofitableness,
