On Incorporeal and Corporeal Beings
1 The subjects considered in the previous chapter have been spoken of in general language, the nature of rational beings being discussed more by way of intelligent inference than strict dogmatic definition, with the exception of the place where we treated, to the best of our ability, of the persons of Father, Son, and Holy Spirit. We have now to ascertain what those matters are which it is proper to treat in the following pages according to our dogmatic belief, i.e., in agreement with the creed of the Church. All souls and all rational natures, whether holy or wicked, were formed or created, and all these, according to their proper nature, are incorporeal; but although incorporeal, they were nevertheless created, because all things were made by God through Christ, as John teaches in a general way in his Gospel, saying, “In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by Him, and without Him was nothing made.” The Apostle Paul, moreover, describing created things by species and numbers and orders, speaks as follows, when showing that all things were made through Christ: “And in Him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by Him, and in Him: and He is before all, and He is the head.” He therefore manifestly declares that in Christ and through Christ were all things made and created, whether things visible, which are corporeal, or things invisible, which I regard as none other than incorporeal and spiritual powers. But of those things which he had termed generally corporeal or incorporeal, he seems to me, in the words that follow, to enumerate the various kinds, viz., thrones, dominions, principalities, powers, influences.
These matters now have been previously mentioned by us, as we are desirous to come in an orderly manner to the investigation of the sun, and moon, and stars by way of logical inference, and to ascertain whether they also ought properly to be reckoned among the principalities on account of their being said to be created in ᾿Αρχάς, i.e., for the government of day and night; or whether they are to be regarded as having only that government of day and night which they discharge by performing the office of illuminating them, and are not in reality chief of that order of principalities.
2. Now, when it is said that all things were made by Him, and that in Him were all things created, both things in heaven and things on earth, there can be no doubt that also those things which are in the firmament, which is called heaven, and in which those luminaries are said to be placed, are included among the number of heavenly things. And secondly, seeing that the course of the discussion has manifestly discovered that all things were made or created, and that among created things there is nothing which may not admit of good and evil, and be capable of either, what are we to think of the following opinion which certain of our friends entertain regarding sun, moon, and stars, viz., that they are unchangeable, and incapable of becoming the opposite of what they are? Not a few have held that view even regarding the holy angels, and certain heretics also regarding souls, which they call spiritual natures.
In the first place, then, let us see what reason itself can discover respecting sun, moon, and stars—whether the opinion, entertained by some, of their unchangeableness be correct—and let the declarations of holy Scripture, as far as possible, be first adduced. For Job appears to assert that not only may the stars be subject to sin, but even that they are actually not clean from the contagion of it. The following are his words: “The stars also are not clean in Your sight.” Nor is this to be understood of the splendour of their physical substance, as if one were to say, for example, of a garment, that it is not clean; for if such were the meaning, then the accusation of a want of cleanness in the splendour of their bodily substance would imply an injurious reflection upon their Creator. For if they are unable, through their own diligent efforts, either to acquire for themselves a body of greater brightness, or through their sloth to make the one they have less pure, how should they incur censure for being stars that are not clean, if they receive no praise because they are so?
3. But to arrive at a clearer understanding on these matters, we ought first to inquire after this point, whether it is allowable to suppose that they are living and rational beings; then, in the next place, whether their souls came into existence at the same time with their bodies, or seem to be anterior to them; and also whether, after the end of the world, we are to understand that they are to be released from their bodies; and whether, as we cease to live, so they also will cease from illuminating the world. Although this inquiry may seem to be somewhat bold, yet, as we are incited by the desire of ascertaining the truth as far as possible, there seems no absurdity in attempting an investigation of the subject agreeably to the grace of the Holy Spirit.
We think, then, that they may be designated as living beings, for this reason, that they are said to receive commandments from God, which is ordinarily the case only with rational beings. “I have given a commandment to all the stars,” says the Lord. What, now, are these commandments? Those, namely, that each star, in its order and course, should bestow upon the world the amount of splendour which has been entrusted to it. For those which are called “planets” move in orbits of one kind, and those which are termed ἀπλανεῖς are different. Now it manifestly follows from this, that neither can the movement of that body take place without a soul, nor can living things be at any time without motion. And seeing that the stars move with such order and regularity, that their movements never appear to be at any time subject to derangement, would it not be the height of folly to say that so orderly an observance of method and plan could be carried out or accomplished by irrational beings? In the writings of Jeremiah, indeed, the moon is called the queen of heaven. Yet if the stars are living and rational beings, there will undoubtedly appear among them both an advance and a falling back. For the language of Job, “the stars are not clean in His sight,” seems to me to convey some such idea.
