Christ spent his ministry teaching his followers to obey the Mosaic Law by word and by example, so if I am a Judaizer for doing that, then so is he, and so should everyone else, but that is not what it means to be a Judaizer.
A Judaizer is one who AFTER THE NEW COVENANT, teaches to obey laws etc from the old covenant. The NT speaks against this and is why most of Christianity does not obey such things. You are in error, not us. That has been shown over and over.
Romans 6:14 For sin shall not have dominion over you: for ye are not under the law, but under grace.
Romans 6:15 What then? shall we sin, because we are not under the law, but under grace? God forbid.
Galatians 3:23 But before faith came, we were kept under the law, shut up unto the faith which should afterwards be revealed.
Galatians 3:24 Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.
Galatians 3:25 But after that faith is come, we are no longer under a schoolmaster.
Galatians 4:21 Tell me, ye that desire to be under the law, do ye not hear the law?
Galatians 4:22 For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman.
Galatians 4:23 But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise.
Galatians 4:24 Which things are an allegory: for these are the two covenants; the one from the mount Sinai, which gendereth to bondage, which is Agar.
Galatians 4:25 For this Agar is mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children.
Galatians 4:26 But Jerusalem which is above is free, which is the mother of us all.
Galatians 5:18 But if ye be led of the Spirit, ye are not under the law.
Romans 7:1 Know ye not, brethren, (for I speak to them that know the law) how that the law hath dominion over a man as long as he liveth?
Romans 7:2 For the woman which hath an husband is bound by the law to her husband so long as he liveth; but if the husband be dead, she is loosed from the law of her husband.
Romans 7:3 So then if, while her husband liveth, she be married to another man, she shall be called an adulteress: but if her husband be dead, she is free from that law; so that she is no adulteress, though she be married to another man.
Romans 7:4 Wherefore, my brethren, ye also are become dead to the law by the body of Christ; that ye should be married to another, even to him who is raised from the dead, that we should bring forth fruit unto God.
We have to be dead to the law in order to marry Christ. If we are not, then we are married to the law and we cannot receive the promises of the new covenant.
Romans 7:5 For when we were in the flesh, the motions of sins, which were by the law, did work in our members to bring forth fruit unto death.
Romans 7:6 But now we are delivered from the law, that being dead wherein we were held; that we should serve in newness of spirit, and not in the oldness of the letter.
Paul says Christians are delivered from the law, because the old covenant law is dead.
