Commentary for Avodah Zarah 128:7

There are a lot of opinions here as to what exactly constitutes a ger toshav. I will focus on the opinion of “others.” Basically, this person keeps the Jewish laws, he just does not want to eat kosher meat. Perhaps the issue here is that fully keeping kosher, especially only eating meat slaughtered in a kosher manner, would separate himself from other people and while he believes in the commandments, he does not want to cut himself off socially from others. This might also be why we can leave him alone with wine—he does not himself make wine into yayin nesekh because he is not an idolater. But since he will have other non-Jews around him for social reasons, if we leave wine with him for a long time by depositing it, it becomes prohibited. In other words, this person believes like a Jew, mostly acts like a Jew, but wants to maintain the tribe of “non-Jew.” I think this has interesting implications as to what it means to be a Jew.
