so you are not jewish by race
It is possible to convert to Judaism or to become a proselyte.
Yes, that is possible. Any person can practice judaism. That was once necessary since, as Jesus told the woman at the well that "salvation is of the Jews". At one time, salvation was only found by converting to Judaism. As Romans 10:4 states, righteousness was at one point through the law.
You don't have to cease to be a Christian to do so.
This is patently false. Salvation was of the jews, now it is not. Righteousness was once through the law, now it is through faith in Christ. There is more:
1Co_10:32 Give none offence, neither to the
Jews, nor to the
Gentiles, nor to
the church of God:
You are either a Jew, a gentile or you are in the church, the body of Christ. You are one of the three, not two of the three.
Gal_3:28 There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
Col_3:11 Where there is neither Greek nor Jew, circumcision nor uncircumcision, Barbarian, Scythian, bond nor free: but Christ is all, and in all.
If you are saved, and in the Body of Christ, you are neither greek nor Jew. You cannot be a christian and an adherent of judaism
Neither Judaism nor Christianity is about salvation by works, only by faith. The old covenant includes the law, the Law of Moses, God's Law.
Like I said, Christ said that salvation was of the jews. He told the woman at the well that salvation was of the Jews:
Joh 4:20 Our fathers worshipped in this mountain; and ye say, that in Jerusalem is the place where men ought to worship.
Joh 4:21 Jesus saith unto her, Woman, believe me, the hour cometh, when ye shall neither in this mountain, nor yet at Jerusalem, worship the Father.
Joh 4:22 Ye worship ye know not what: we know what we worship: for salvation is of the Jews.
Jesus confirmed what the Jews said about the samaritans, that worship was to be in Jerusalem. That is one work right there. And you no longer obtain righteousness through the law (Rom 10:4), which at one point is the only way you could obtain righteousness (Deut 6:25) because God was not giving the gift of imputed righteousness to the jews under the law.
There is also the new covenant. People do observe Passover after the coming of Christ. I observe Passover.
Christians do not observe the passover. There is no need as I have clearly demonstrated that scripture clearly says you are one or the other. you are kidding yourself. there is no scriptural support for any of your position unless I am missing something. Can you address the scripture i used and provide some of your own to support your position?
