When we say that man chooses for himself, we do mean that every one of us must choose himself; but by that we also mean that in choosing for himself he chooses for all men. For in effect, of all the actions a man may take in order to create himself as he wills to be, there is not one which is not creative, at the same time, of an image of man such as he believes he ought to be. To choose between this or that is at the same time to affirm the value of that which is chosen; for we are unable ever to choose the worse. What we choose is always the better; and nothing can be better for us unless it is better for all.
Biblical scholars tend to see Yeshua’s message as meant for Jews per se, extending to the treatment of non-Jews yes, but as Jews should treat them. And this does not include treating them as Jews. The golden rule has a very different meaning when it is a circumscribed, in-group prescription. In this form, its application is guided by hosts of assumptions, expectations, traditions, and religious obligations, recognized like-mindedly by “the tribe.” This helps solve the ambiguity problem of how to apply the rule within different roles: parents dealing with children, supervisors with rank-and-file employees, and the like.
