Accordingly we find the Holy Spirit, to use a language and a phraseology peculiar to his own divine self, declaring that God created all things by his Word or by speaking them into being; "He spake and it was done"; that he wrought all things by his Word; and that all the works of God are certain words of God, certain things created by the uncreated word. As therefore the philosopher uses his own terms, so the Holy Ghost uses his. Hence when the astronomer speaks of his spheres, his cycles and his epicycles, he does so rightly, for it is lawful for him in the profession of his art to use such terms as may enable him the better to instruct his disciples. On the other hand the Holy Ghost will know nothing of such terms in the sacred Scriptures. Hence those Scriptures call the whole of that part of the creation which is above us, "The heaven," nor ought that term to be disapproved by the astronomer; for the astronomer and the Scripture both adopt, as I have said, terms peculiar to themselves. It is in this manner that we are to understand the term "seasons" in the sacred text before us. For the term "season" with the philosopher and with the Hebrew has not the same signification. With the Jews the term "season" signifies, theologically, an appointed feast or festival; and also the intervals of days, which concur and conjoin to form the year, wherefore this term is everywhere rendered by the word "feast" or "festival" or "festivity"; except where it is used to signify a "tabernacle" or "tent." I deemed it best to offer these admonitions concerning language and phraseology before we advance further, and I hope they will not be found useless or out of place, as showing the importance that every art should confine itself to its own language and terms; that no one art should condemn or deride another, but that each should rather aid the other and render mutual services. And this indeed the professors of all arts do, in order that the unity of the whole state may be preserved; which, as Aristotle says, "cannot be constituted of a physician and a physician; but must be formed of a physician and a husbandman." PART V. GOD'S WORK ON THE FIFTH DAY. I. V. 20. _And God said, Let the waters swarm with swarms of living creatures, and let birds fly above the earth,_ etc., etc. We see Moses retains invariably the same sacred phraseology, "And God said," etc. Hitherto he has been speaking of the superior creatures; the heaven with all its host of planets and stars, which God created out of water by the Word, and gave light unto it, just as we now see the air around us lucid, with a natural illumination.
