Moses has already said that the rude mass of heaven and earth which he also calls "darkness" and "the deep," was made by the Word; and that work ought to be considered the work of the "first day." Yet, it is now for the first time that Moses uses the expression "God said, Let there be light," etc. A marvelous phraseology this indeed; unknown to any writer of any other language under heaven, that God by speaking causes that to exist, which had no existence before. Here therefore Moses sets before us the medium and instrument which God used in performing his works, namely the Word. But we must here carefully mark the distinction in the Hebrew language between the words AMAR and DABAR. We render each by the terms to say or to speak. But, in the Hebrew there is this difference: AMAR only and properly signifies the word uttered. But DABAR means also the thing or substance uttered. As when the prophets say "This is the Word of the Lord," they use the term DABAR not AMAR. Even at this day the new Arians blind the eyes of those unacquainted with the Hebrew language by saying that the term in question implies, and is, "a thing created;" and that in this way it is that Christ is called the Word. Against this impious, and at the same time ignorant, corruption of the term Word, the reader is duly warned, and exhorted to remember that Moses here uses the word AMAR which simply and properly signifies the word uttered; so that the word uttered is something distinct from him who utters it; as here is also a distinction between the person speaking and the thing spoken. Therefore we have before proved from this text a plurality of persons; so here is also an evident distinction of persons; for it affirms that it is God the speaker, if I may so express myself, who creates; and yet he uses no material; but creates the heavens and the earth out of nothing by the sole word he utters. Compare here the Gospel of St. John "In the beginning was the Word." He exactly agrees with Moses. He says that there was no creature whatever before the world was made. Yet God possessed the Word. And what is this Word and what does it do? Hear Moses. The light, says he, as yet was not; but the darkness out of its nothing-state is changed into that most excellent creature, light. By what? By the Word. Therefore, "in the beginning" and before every creature is the Word; and it is so powerful that out of nothing it makes all things. Hence that irrefragably follows, which John eloquently adds, that the Word was and is God! And yet, that the Word is a person different from God the Father; even as the Word, and he who utters the Word, are things absolutely distinct from each other. But at the same time this distinction is of the nature that the most perfect oneness, if I may so speak, of unity remains.
