He thus ruled that people act in goodwill and in unity, for each person must consider him or herself as a citizen of the one and only republic. He planted this love and charity in human hearts at the very moment that He taught humans knowledge and wisdom, for humankind in its entirety was created by a single God. The progeny of one father, Adam, followed by the seed of Noah, went on to multiply throughout the world. The prophet Malachi therefore said, “Have we not all one Father? Did not one God create us? Why do we break faith with one another, profaning the covenant of our ancestors?” The prophet calls on two reasons to arouse this tender love in our hearts, to love one another and not wound the other’s pride. First, because humankind all share the same Father and are therefore equally related and free; they share in the inheritance of the world's riches. Second, because we are the creations of one God and His creatures… All we have said thus far serves as faithful testimony and true evidence that a Jew may not commit any inhumane deed that risks hurting any person whose customs and faith differ from Jewish customs and faith – so long as the person respect moral laws and not be impaired by any evil or ugly attribute, and that the person recognize supreme Providence and its unlimited power, its ultimate mercy and wisdom, that rules and sustains everything.
