2. Then, in the next place, we must know that every being which is endowed with reason, and transgresses its statutes and limitations, is undoubtedly involved in sin by swerving from rectitude and justice. Every rational creature, therefore, is capable of earning praise and censure: of praise, if, in conformity to that reason which he possesses, he advance to better things; of censure, if he fall away from the plan and course of rectitude, for which reason he is justly liable to pains and penalties. And this also is to be held as applying to the devil himself, and those who are with him, and are called his angels. Now the titles of these beings have to be explained, that we may know what they are of whom we have to speak. The name, then, of Devil, and Satan, and Wicked One, who is also described as Enemy of God, is mentioned in many passages of Scripture. Moreover, certain angels of the devil are mentioned, and also a prince of this world, who, whether the devil himself or some one else, is not yet clearly manifest. There are also certain princes of this world spoken of as possessing a kind of wisdom which will come to nought; but whether these are those princes who are also the principalities with whom we have to wrestle, or other beings, seems to me a point on which it is not easy for any one to pronounce. After the principalities, certain powers also are named with whom we have to wrestle, and carry on a struggle even against the princes of this world and the rulers of this darkness. Certain spiritual powers of wickedness also, in heavenly places, are spoken of by Paul himself. What, moreover, are we to say of those wicked and unclean spirits mentioned in the gospel? Then we have certain heavenly beings called by a similar name, but which are said to bend the knee, or to be about to bend the knee, at the name of Jesus; nay, even things on earth and things under the earth, which Paul enumerates in order. And certainly, in a place where we have been discussing the subject of rational natures, it is not proper to be silent regarding ourselves, who are human beings, and are called rational animals; nay, even this point is not to be idly passed over, that even of us human beings certain different orders are mentioned in the words, “The portion of the Lord is His people Jacob; Israel is the cord of His inheritance.” Other nations, moreover, are called a part of the angels; since “when the Most High divided the nations, and dispersed the sons of Adam, He fixed the boundaries of the nations according to the number of the angels of God.” And therefore, with other rational natures, we must also thoroughly examine the reason of the human soul.
