Thomas Aquinas

Above he warned that they should not fall away from the faith through any deceit of speech; here he sets down the reason for the warning, which is taken from the goods that were in them, which they ought not to lose, but rather to progress in. And first he recalls the goods they had; second he shows how they may progress in them, at the place "as therefore." Concerning the first he does two things: for first he shows how their goods are known to him; second, what goods are in them, at the place "rejoicing."

He says therefore "for even if," etc.; as if to say: although I have not preached to you, nor do I see your deeds with my eyes, yet I am present with you in spirit, rejoicing in affection over your goods. 1 Cor. 5:3: "absent indeed in body, but present in spirit." Prov. 10:1: "a wise son makes glad his father," etc. And this because it was revealed to him through the Holy Spirit, and therefore he says "but in spirit I am with you." 4 Kings 5:26: "was not my heart present, when the man returned from the chariot to meet you," etc.

"Rejoicing," I say, "I am," because I am seeing the order, that is, your ordered conduct. 1 Cor. 14:40: "let all things be done honestly and according to order among you." Judg. 5:20: "the stars remaining in their order and their course," etc. And "the firmness," etc. 2 Tim. 2:19: "the firm foundation of God stands," etc. And this "in Christ." Eph. 3:17: "that Christ may dwell through faith in your hearts," etc. For the Church is a spiritual building. Eph. 2:21: "in whom every building, being constructed, grows into a holy temple in the Lord." Now the goodness of this consists in a due foundation, which is faith, and in a due superstructure. And therefore he set down these two.

Then when he says "as therefore," etc., he warns them to keep these things. And first, to progress; second, to persist; third, to give thanks. He says therefore: "as you received Christ our Lord," without perverting it, "walk in him." Rom. 12:9: "cleaving to what is good." The Church is sometimes compared to a spiritual building. 1 Cor. 3:17: "the temple of God is holy, which you are." Sometimes to a tree, because it bears fruit. And the same is the comparison of the foundation to the house, and of the root to the tree, because the firmness of each—root and foundation—is Christ. Isa. 11:10: "there shall be the root of Jesse, which stands as a sign of the peoples." 1 Cor. 3:11: "no one can lay another foundation besides that which has been laid, which is Christ Jesus." Therefore he says "rooted," namely as good branches, "and built up in him," and "confirmed," namely as good stones, that is, if you persist in his faith. 1 Pet., last chapter: "your adversary," etc., and afterward: "resist him, strong in faith," etc. And this "as you have learned," namely in the true faith. Gal. 1:9: "if anyone preaches to you a gospel besides that which you have received, let him be anathema," etc. "Abounding in him in thanksgiving," that is, giving thanks abundantly. 1 Thess., last chapter: "in all things give thanks." 2 Macc. 1:11: "having been delivered from great dangers by God, we give magnificent thanks to him," etc.

Then when he says "see," he warns lest they be deceived through vain wisdom. And first he sets down the warning; second, the reason, at the place "in him." Concerning the first, first he teaches to avoid what can deceive; second he shows why it deceives, at the place "according to the tradition." But that someone be deceived through secular wisdom happens in two ways, namely sometimes through the real principles of philosophy, sometimes through sophistic reasonings. And he teaches to beware of both. Hence he says "lest anyone," etc., that is, through philosophical teachings. Isa. 47:10: "your wisdom and this knowledge have deceived you." For many, on account of philosophy, are deceived, straying from the faith. Jer. 10:14: "every man has become foolish by his own knowledge."

As to the second he says "and vain deceit," which is founded only upon the apparent entanglement of words. Eph. 5:6: "let no one seduce you with vain words." But how does one seduce? He who seduces must have something apparent, and something not existing. Therefore he first sets down the principle of appearance; second, the lack of existence. The principle of appearance is twofold, that is, the authority of the philosophers—and as to this he says "according to the tradition of men," that is, according to what some have handed down by their own reasoning. Ps. 93:11: "the Lord knows the thoughts of men, that they are vain." The other is the invention of reason, namely when someone wishes to measure the things that belong to faith according to the principles of things and not according to divine wisdom. For by this many are deceived. And therefore he says "according to the elements of the world," etc. Wis. 13:1: "nor by attending to the works did they know who the craftsman was," etc.

For the higher a cause is, the more elevated an effect it has. Hence whoever wishes to consider higher effects according to lower causes is deceived; as if someone should consider the motion of water according to the power of water, he cannot know the cause of the ebbing of the sea, but he can, if he considers it according to the power of the moon. Hence much more is he deceived who considers the proper effects of God according to the elements of the world. And this is the cause of the appearance.

But are the traditions of men and their reasonings always to be rejected? I answer: no, but only when physical reasoning proceeds according to them, and not according to Christ. Below, in the same [chapter]: "not holding the head, from which the whole body, supplied and joined together through ligaments and joints, grows with the increase of God." Or it can be explained "according to the elements of the world," namely by measuring the truth of faith according to the truth of creatures. Or he says this on account of idolaters who worship idols, calling the sky Jove. Or according to the Jews, so that the sense is "through philosophy," that is, through the reasoning of those wishing to draw people to legal observances, "according to the elements of the world," that is, according to bodily observances. Gal. 4:3: "we were serving under the elements of the world." But the first exposition is better.

Then when he says "because in him," etc., he sets down the reason for the foregoing, saying: whatever is not according to Christ is to be rejected. But is Christ so great that for his sake all things ought to be rejected? And he answers that indeed so; which he shows in three ways: first by comparison to the divinity; second by comparison to the faithful, at the place "and you are"; third by comparison to the Angels, at the place "who is the head."

He says therefore: what is against him is to be rejected for this reason, that he himself is God. Hence one must stand by him more than by all, because "in him dwells," etc. For God is in all things, but in some by participation in the likeness of his goodness, as in a stone and other such things. And such things are not God, but have in themselves something of God; not his substance, but a likeness of his goodness. And therefore the fullness of divinity does not dwell in them, because it is not there according to substance. Likewise he is in holy minds through operation, which through love and knowledge attain to God. And therefore God is in them according to grace, but not bodily, but according to the effect of grace; nor is it the fullness, but according to certain limited effects.

But in Christ he is bodily, which is explained in three ways. For "body" is divided against "shadow." Below, in the same [chapter]: "which are a shadow of things to come," etc. And thus it happens that God dwells in two ways, either according to shadow, or bodily, that is, really. In the first way he dwelt in the old law, but in Christ he dwelt bodily, that is, really and according to truth. It is explained in a second way, because the other saints are indwelt only according to the soul, not according to the body. Rom. 7:18: "I know that good does not dwell in me," that is, in my flesh; but in Christ divinity dwells bodily: because the indwelling of God, by which he indwells the saints, is through operation, that is, through love and knowledge, which is the work of the rational mind alone; but in Christ he dwells through the assumption of man into the unity of person. Hence whatever pertains to man is wholly indwelt by God: and therefore flesh and mind are indwelt, because both are united to the Word. John 1:14: "and the Word was made flesh."

But there is a third way of the sense. For God is in things in three ways: one is common, through power, presence, and essence; another is through grace in the saints; the third mode is singular, in Christ, through union. Now a body has three dimensions. And the fullness of divinity, in these modes, superabounds in Christ; therefore it is said to be in him bodily. And the first mode indeed is as it were length, because it extends itself to all things; likewise breadth is through charity; likewise as to depth, it is incomprehensible.

But from this Nestorius errs, saying that the union was made only through indwelling, saying that the Word dwelt in the flesh. But against this is what the Apostle says, Phil. 2:7: "he emptied himself," etc. But to dwell in man is not to empty oneself, but to become man; and he adds: "made in the likeness of men," and therefore Christ is called habitable, not as though he who dwells and he who is indwelt were different, but he himself is both man and God, in whom the fullness of divinity dwells.

Then when he says "and you are in him," etc., he shows the same thing by comparison to others. As if to say: you have received all things. John 1:16: "of his fullness," etc. Now it should be known that the Platonists say that divine gifts come to men through the mediation of separate substances. And this is true also according to Dionysius, but this is something special, because it comes immediately from him who fills the Angels. John 1:18: "the only-begotten Son of God, who is in the bosom of the Father, he has declared," etc. Heb. 2:3: "when it had received a beginning to be declared through the Lord, from those who heard it," etc. And therefore he says "who is the head of all principality and power," insofar as he is their king and lord, not through conformity of nature, for in that way he is the head of men. And he touches upon these orders, which seem to have a certain preeminence.
