Thomas Aquinas - Summa Theologica, Part III (Tertia Pars)

Now both these things were to be made known to men concerning Christ—namely, that God dwelt in Him by grace, not of adoption, but of union: and that His supernatural doctrine was from God. And therefore it was most fitting that He should work miracles. Wherefore He Himself says (John 10:38): "Though you will not believe Me, believe the works"; and (John 5:36): "The works which the Father hath given Me to perfect . . . themselves . . . give testimony to Me."

Reply Obj. 1: These words, "a sign shall not be given it, but the sign of Jonas," mean, as Chrysostom says (Hom. xliii in Matth.), that "they did not receive a sign such as they sought, viz. from heaven": but not that He gave them no sign at all. Or that "He worked signs not for the sake of those whom He knew to be hardened, but to amend others." Therefore those signs were given, not to them, but to others.

Reply Obj. 2: Although Christ came "in the infirmity" of the flesh, which is manifested in the passions, yet He came "in the power of God" [*Cf. 2 Cor. 13:4], and this had to be made manifest by miracles.

Reply Obj. 3: Miracles lessen the merit of faith in so far as those are shown to be hard of heart who are unwilling to believe what is proved from the Scriptures unless (they are convinced) by miracles. Yet it is better for them to be converted to the faith even by miracles than that they should remain altogether in their unbelief. For it is written (1 Cor. 14:22) that signs are given "to unbelievers," viz. that they may be converted to the faith. _______________________

SECOND ARTICLE [III, Q. 43, Art. 2]

Whether Christ Worked Miracles by Divine Power?

Objection 1: It would seem that Christ did not work miracles by Divine power. For the Divine power is omnipotent. But it seems that Christ was not omnipotent in working miracles; for it is written (Mk. 6:5) that "He could not do any miracles there," i.e. in His own country. Therefore it seems that He did not work miracles by Divine power.

Obj. 2: Further, God does not pray. But Christ sometimes prayed when working miracles; as may be seen in the raising of Lazarus (John 11:41, 42), and in the multiplication of the loaves, as related Matt. 14:19. Therefore it seems that He did not work miracles by Divine power.

Obj. 3: Further, what is done by Divine power cannot be done by the power of any creature. But the things which Christ did could be done also by the power of a creature: wherefore the Pharisees said (Luke 11:15) that He cast out devils "by Beelzebub the prince of devils." Therefore it seems that Christ did not work miracles by Divine power.

On the contrary, our Lord said (John 14:10): "The Father who abideth in Me, He doth the works."

I answer that, as stated in the First Part (Q. 110, A. 4), true miracles cannot be wrought save by Divine power: because God alone can change the order of nature; and this is what is meant by a miracle. Wherefore Pope Leo says (Ep. ad Flav. xxviii) that, while there are two natures in Christ, there is "one," viz. the Divine, which shines forth in miracles; and "another," viz. the human, "which submits to insults"; yet "each communicates its actions to the other": in as far as the human nature is the instrument of the Divine action, and the human action receives power from the Divine Nature, as stated above (Q. 19, A. 1).

Reply Obj. 1: When it is said that "He could not do any miracles there," it is not to be understood that He could not do them absolutely, but that it was not fitting for Him to do them: for it was unfitting for Him to work miracles among unbelievers. Wherefore it is said farther on: "And He wondered because of their unbelief." In like manner it is said (Gen. 18:17): "Can I hide from Abraham what I am about to do?" and Gen. 19:22: "I cannot do anything till thou go in thither."

Reply Obj. 2: As Chrysostom says on Matt. 14:19, "He took the five loaves and the two fishes, and, looking up to heaven, He blessed and brake: It was to be believed of Him, both that He is of the Father and that He is equal to Him . . . Therefore that He might prove both, He works miracles now with authority, now with prayer . . . in the lesser things, indeed, He looks up to heaven"—for instance, in multiplying the loaves—"but in the greater, which belong to God alone, He acts with authority; for example, when He forgave sins and raised the dead."

When it is said that in raising Lazarus He lifted up His eyes (John 11:41), this was not because He needed to pray, but because He wished to teach us how to pray. Wherefore He said: "Because of the people who stand about have I said it: that they may believe that Thou hast sent Me."

Reply Obj. 3: Christ cast out demons otherwise than they are cast out by the power of demons. For demons are cast out from bodies by the power of higher demons in such a way that they retain their power over the soul: since the devil does not work against his own kingdom. On the other hand, Christ cast out demons, not only from the body, but still more from the soul. For this reason our Lord rebuked the blasphemy of the Jews, who said that He cast out demons by the power of the demons: first, by saying that Satan is not divided against himself; secondly, by quoting the instance of others who cast out demons by the Spirit of God; thirdly, because He could not have cast out a demon unless He had overcome Him by Divine power; fourthly, because there was nothing in common between His works and their effects and those of Satan; since Satan's purpose was to "scatter" those whom Christ "gathered" together [*Cf. Matt. 12:24-30; Mk. 3:22; Luke 11:15-32]. _______________________

THIRD ARTICLE [III, Q. 43, Art. 3]

Whether Christ Began to Work Miracles When He Changed Water into Wine at the Marriage Feast?

Objection 1: It would seem that Christ did not begin to work miracles when He changed water into wine at the marriage feast. For we read in the book De Infantia Salvatoris that Christ worked many miracles in His childhood. But the miracle of changing water into wine at the marriage feast took place in the thirtieth or thirty-first year of His age. Therefore it seems that it was not then that He began to work miracles.

Obj. 2: Further, Christ worked miracles by Divine power. Now He was possessed of Divine power from the first moment of His conception; for from that instant He was both God and man. Therefore it seems that He worked miracles from the very first.

Obj. 3: Further, Christ began to gather His disciples after His baptism and temptation, as related Matt. 4:18 and John 1:35. But the disciples gathered around Him, principally on account of His miracles: thus it is written (Luke 5:4) that He called Peter when "he was astonished at" the miracle which He had worked in "the draught of fishes." Therefore it seems that He worked other miracles before that of the marriage feast.

On the contrary, It is written (John 2:11): "This beginning of miracles did Jesus in Cana of Galilee."

I answer that, Christ worked miracles in order to confirm His doctrine, and in order to show forth His Divine power. Therefore, as to the first, it was unbecoming for Him to work miracles before He began to teach. And it was unfitting that He should begin to teach until He reached the perfect age, as we stated above, in speaking of His baptism (Q. 39, A. 3). But as to the second, it was right that He should so manifest His Godhead by working miracles that men should believe in the reality of His manhood. And, consequently, as Chrysostom says (Hom. xxi in Joan.), "it was fitting that He should not begin to work wonders from His early years: for men would have deemed the Incarnation to be imaginary and would have crucified Him before the proper time."

Reply Obj. 1: As Chrysostom says (Hom. xvii in Joan.), in regard to the saying of John the Baptist, "'That He may be made manifest in Israel, therefore am I come baptizing with water,' it is clear that the wonders which some pretend to have been worked by Christ in His childhood are untrue and fictitious. For had Christ worked miracles from His early years, John would by no means have been unacquainted with Him, nor would the rest of the people have stood in need of a teacher to point Him out to them."
