Rosner, Fred, The Existence and Unity of God, Three Treatises Attributed to Moses Maimonides, Jason Aronson, Inc., 1990. “Treatise on the Unity of God, known in Hebrew as Ma’amar Hayichuel, a paraphrase of the first two volumes of the Rambam’s Mishneh Torah, was written by the Rambam, asserts Rosner.  Its purpose was to provide non-Jews with a synopsis of Jewish theology, philosophy, and ethics.”
