Maimonides does not mention the term Creator except in the beginning of each paragraph as a substitute for “God.” He employs the philosophical term “First Cause” in defining the existence of God. In the sixty-ninth chapter of the first book of “The Guide” we find the explanation thereof. He says: “The philosophers, as you know, call God the First Cause (‏עִלָּה‎ and ‏סִבָּה‎); but those who are known by the name Mutakallemim (Mohammedan theologians) are very much opposed to the use of that name, and prefer to call Him ‘Maker’ (‏פּוֹעֵל‎), believing that there is a great difference whether we use the one term or the other. They argue thus: Those who say that God is the Cause, implicitly assume the coexistence of the Cause with that which was produced by that Cause, and believe that the universe is eternal, and that it is inseparable from God. Those, however, who say that God is the Maker do not assume the coexistence of the maker with his work; for the maker can exist anterior to his work; we cannot even imagine how a maker can be in action unless he existed before his own work. This is an argument advanced by persons who do not distinguish between the potential and the actual. For there is no difference whether we say ‘cause’ or ‘maker;’ ‘cause’ as a mere potentiality precedes its effect; and ‘cause’ as actuality coexists with its effect. The same is the case with ‘maker;’ so long as the work is not done, he is a maker potentially, and exists before his work; he is an actual maker when the work is done, and then he coexists with his work.” “The reason why the philosophers called God ‘the Cause’ and did not call Him ‘the Maker’ is not to be sought in their belief that the universe is eternal, but in other principles, which I will briefly explain to you. Everything owes its origin to the following four causes: the substance, the form, the agens, the final cause. The philosophers believe—and I do not differ from them—that God is the agens, the form, and the final cause of everything; in order to express this, they call God ‘the Cause’ of all things. Every one of these three causes leads, through a chain of causes, to God as the First Cause.” Maimonides further points out in this chapter that the choice of the term by no means decides the question whether the universe has had a beginning or not.
