I bear no responsibility for not introducing Judaism to the gentile.
I don't know of any rabbinical teachings to this effect, but I would not feel responsible for not taking the first step to introduce Jewish observance to a non-observant Jew.
First of all, as I wrote above, Jews are directed NOT to try to reform someone who is not likely to accept the reform. The rejection that will result is seen as a degradation of G-d. Therefore, if a religious Jew feels that his importuning is likely to be spurned (for example, if he sees a Jewish man riding in a car on the Sabbath or eating shellfish), he probably won't say anything didactic.
There is a Jewish concept called "kiruv", or outreach, which embraces Jews of all levels of observance and encourages them to become more observant. Even most kiruv, however, is limited to people who themselves take the initiative and ask for help with their observance or their understanding of Jewish doctrine. However, if a non-observant Jew were to sincerely ask an observant Jew -- who is not involved in kiruv -- for guidance, he most likely would be given a straightforward answer to his questions and then possibly referred to a kiruv organization.
There is only one Jewish movement that I am aware of that actually initiates outreach to non-observant Jews, and that is the Lubavitch Hassidic movement. Those are the people whom cookcounty wrote about above. As cookcounty wrote, a few Lubavitch Hassidim approached him while he was in Israel in order to encourage him to engage in a particular Jewish observance. When they found out that he is not Jewish, they turned on their heels since -- as I wrote above -- Jews do not proselytize people of other faiths.
"Jews do not proselytize people of other faiths."
I was speaking of people that had no faith, belonged to no religious affilation...
I Thank You for your post, but I think now I understand
I have heard people say that Many Jews are uncaring and un-feeling maybe they say that because they do not understand like I didn't that in Judiasm there is no obligation to reach out to people and introduce them to GOD.
In Christianity it is a must to reach out to the lost and hopeless and introduce them to GOD his peace, love and forgiveness, at least we are making a start in understanding each other's faiths...
I'm sorry if you misunderstood my point. I was emphasizing that the Lubavitchers in that case were the most aggressive religious folk that I have ever come across in my 56 years of association with variious evangelistic christian groups. I have heard all the stories about forced baptisms and kidnappings, etc., but I have to tell you I have never personally seen such tactics. I'm sure (especially in less gentle times) those things occurred. But I just haven't seen it.
