Well,there’s no going back to Christianity. Once a person converts to Judaism they are Jewish for life. And I have no desire to go back.
I made a commitment to Judaism and to the Jewish people and I can’t go back on that.
It saddens and troubles me that this professor left Judaism and abandoned the Torah.
There is nothing for me to contemplate.
I see. Well, it is a free country. You are entitled to your choices.
Of course, your statement, “Once a person converts to Judaism they are Jewish for life,” is nonsense. It does not comport to the world we, or anyone else, lives in or ever has lived in. Nor does it comport to what the OT Scriptures say. Whether you see that now or later is inconsequential. And, while it may sadden and trouble you, it did not sadden and trouble him, as his entire lifetime thereafter testifies. And, as to whether you or he is in a position of greater knowledge, I will admit that I don’t know you at all. Him I do. I doubt you are of greater knowledge. I doubt it severely ... and I doubt it again ... and again ... and again. And I doubt even more sincerely that he thought he was abandoning the Torah - which he knew better in Hebrew than in German, Latin, or Norwegian, none of which, I dare say, I think you know.
So, contemplate nothing, if you will. That is your choice.
It is not a choice I would make.
Good day to you, sir.
This statement manifests one neither understands Christianity nor conversion.
Nobody is able to convert to Christianity on their own. If they do, it isn't Christianity. Even Jesus Christ Himself is unable to convert a human to Christianity. Only one person is empowered to convert an unbeliever to a believer and that is God the Holy Spirit. God the Father elects, God the Son provides the Sacrifice and Word, and God the Holy Spirit regenerates the human spirit in the new man.
Once God the Holy Spirit regenerates the human spirit, the believer becomes Christian with everlasting life, a member of His Royal Family.
Even if a Christian falls away from faith, and rejects the Son later, in rebellion to God's Plan, this doesn't remove him from that family any more than divorcing oneself from one's parents removes one's parents could remove one's genetic familial ties.
It might place one out of fellowship with God, but God still indwells the believer, not by the volition of the believer, but by the volition of God, also known as His Sovereignty.
The stories and academic elaborations of the Law by the Midrash do not trump His Word, though they may provide academic study. It provides academic analysis of His Word, but fails to provide education or a method of thinking provided by God. The Torah and the New Testament are consistent and parts of His Word. Both are true. Both are provided for us to think through faith in Him.
For guidance on who is a true Jew, study Romans (Chapter 2) with emphasis on the significance of circumcision.
For guidance on why Israel is blind to Christ, study Romans, Chapter 11:25-36, although it was scribed by the Apostle to the Gentiles.
