I've seen many goyim come out of xianity and convert to Judaism without being coaxed out by a Rabbi or even a Jew. Some of these former xians never even knew a Jew before approaching a Rabbi for the purpose of learning for conversion. They were discouraged and turned away several times as was the custom of the Jewish people until recently. If someone is sincerely searching for the truth, Hashem will lead them to it. Of course this was before certain Rabbis starting "teaching" in xian churches and hosting xian groups in Israel under the guise of "being a light unto the nations". So, you could see how I could wonder how a xian can "learn Torah" from an Orthodox Rabbi for 5 or 10 years and still believe his idolatrous beliefs. Then I heard that these Rabbis are telling the xians it's ok for them to be xians. It's ok for them to worship a man-god? It's ok for them to teach that the NT is the word of G-d? It's ok for them to spread lies throughout the world and pass it off as the truth? And these Rabbi's call xians righteous gentiles? I'm shocked. Even if it was ok, which I don't believe (see Idolatry and the Customs of the Nations,Torah for the Nations, Christianity: OK for xians?, ), it isn't desirable to the creator of the world. It is hard enough to leave a false religion without a Jew, who is supposed to have the truth, telling you there's no need to leave it. These Rabbis are spreading darkness not light. They are also causing unnecessary pain to true bnai Noach and converts who left that false religion. Many bnai Noach feel lost and rejected because many Rabbis are spending all of their time teaching xians and some of the Rabbis who are teaching bnai Noach are teaching things that not only are not true but dangerous (see "the Torah of Shem). I understand that Hashem allows lies to be spread, as well as truth, to maintain free will but it is getting harder and harder to find the truth. Any sincere Rabbi who is teaching xians should keep the words of Rebbi Nachman in mind. Being a light unto the nations is not a commandment, it is a statement of fact. When we as a people keep mitzvot and serve Hashem we shine like a light of a lighthouse showing the correct path.
