Have you ever noticed the enormous emphasis on social ethics in Islam and Rabbinical Judaism? Jewish philosophers are generally social commentators and existentialists. They don’t focus on God the way Christian philosophers and theologians do. To the extent that they talk about God, it’s God as the source of morality. Same thing with so much Islamic discourse.

In that regard it’s not coincidental that Islam and Rabbinical Judaism are militantly unitarian. Anti-incarnational.

Because the Deity of Islam and Rabbinical Judaism is not an essentially interpersonal being, because the idea of a divine Incarnation is inimical to their theology, the Deity of Islam and Rabbinical Judaism is very abstract. Inscrutable. Ineffable.

The result is to collapse the vertical dimension of religion to the horizontal dimension. We’re reduced to immanence. Human relationships. That’s because a unitarian Deity isn’t very relatable. From above, he creates and sustains a moral and metaphysical framework. And that’s about it. A unitarian Deity isn’t very engaging, approachable, or sociable–unlike an Incarnational, Trinitarian Deity. A religion of rules that never rises above human social dynamics. A unitarian Deity can be a benefactor, but not a friend or father.
