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

I answer that, As knowledge is imparted through a syllogism from something which we know better, so knowledge given by signs must be conveyed through things which are familiar to those to whom the knowledge is imparted. Now, it is clear that the righteous have, through the spirit of prophecy, a certain familiarity with the interior instinct of the Holy Ghost, and are wont to be taught thereby, without the guidance of sensible signs. Whereas others, occupied with material things, are led through the domain of the senses to that of the intellect. The Jews, however, were accustomed to receive Divine answers through the angels; through whom they also received the Law, according to Acts 7:53: "You [Vulg.: 'who'] . . . have received the Law by the disposition of angels." And the Gentiles, especially astrologers, were wont to observe the course of the stars. And therefore Christ's birth was made known to the righteous, viz. Simeon and Anna, by the interior instinct of the Holy Ghost, according to Luke 2:26: "He had received an answer from the Holy Ghost that he should not see death before he had seen the Christ of the Lord." But to the shepherds and Magi, as being occupied with material things, Christ's birth was made known by means of visible apparitions. And since this birth was not only earthly, but also, in a way, heavenly, to both (shepherds and Magi) it is revealed through heavenly signs: for, as Augustine says in a sermon on the Epiphany (cciv): "The angels inhabit, and the stars adorn, the heavens: by both, therefore, do the 'heavens show forth the glory of God.'" Moreover, it was not without reason that Christ's birth was made known, by means of angels, to the shepherds, who, being Jews, were accustomed to frequent apparitions of the angels: whereas it was revealed by means of a star to the Magi, who were wont to consider the heavenly bodies. Because, as Chrysostom says (Hom. vi in Matth.): "Our Lord deigned to call them through things to which they were accustomed." There is also another reason. For, as Gregory says (Hom. x in Evang.): "To the Jews, as rational beings, it was fitting that a rational animal [*Cf. I, Q. 51, A. 1, ad 2]," viz. an angel, "should preach. Whereas the Gentiles, who were unable to come to the knowledge of God through the reason, were led to God, not by words, but by signs. And as our Lord, when He was able to speak, was announced by heralds who spoke, so before He could speak He was manifested by speechless elements." Again, there is yet another reason. For, as Augustine [*Pope Leo] says in a sermon on the Epiphany: "To Abraham was promised an innumerable progeny, begotten, not of carnal propagation, but of the fruitfulness of faith. For this reason it is compared to the multitude of stars; that a heavenly progeny might be hoped for." Wherefore the Gentiles, "who are thus designated by the stars, are by the rising of a new star stimulated" to seek Christ, through whom they are made the seed of Abraham.

Reply Obj. 1: That which of itself is hidden needs to be manifested, but not that which in itself is manifest. Now, the flesh of Him who was born was manifest, whereas the Godhead was hidden. And therefore it was fitting that this birth should be made known by angels, who are the ministers of God. Wherefore also a certain "brightness" (Luke 2:9) accompanied the angelic apparition, to indicate that He who was just born was the "Brightness of" the Father's "glory."

Reply Obj. 2: The righteous did not need the visible apparition of the angel; on account of their perfection the interior instinct of the Holy Ghost was enough for them.

Reply Obj. 3: The star which manifested Christ's birth removed all occasion of error. For, as Augustine says (Contra Faust. ii): "No astrologer has ever so far connected the stars with man's fate at the time of his birth as to assert that one of the stars, at the birth of any man, left its orbit and made its way to him who was just born": as happened in the case of the star which made known the birth of Christ. Consequently this does not corroborate the error of those who "think there is a connection between man's birth and the course of the stars, for they do not hold that the course of the stars can be changed at a man's birth."

In the same sense Chrysostom says (Hom. vi in Matth.): "It is not an astronomer's business to know from the stars those who are born, but to tell the future from the hour of a man's birth: whereas the Magi did not know the time of the birth, so as to conclude therefrom some knowledge of the future; rather was it the other way about."

Reply Obj. 4: Chrysostom relates (Hom. ii in Matth.) that, according to some apocryphal books, a certain tribe in the far east near the ocean was in the possession of a document written by Seth, referring to this star and to the presents to be offered: which tribe watched attentively for the rising of this star, twelve men being appointed to take observations, who at stated times repaired to the summit of a mountain with faithful assiduity: whence they subsequently perceived the star containing the figure of a small child, and above it the form of a cross.

Or we may say, as may be read in the book De Qq. Vet. et Nov. Test., qu. lxiii, that "these Magi followed the tradition of Balaam," who said, "'A star shall rise out of Jacob.' Wherefore observing this star to be a stranger to the system of this world, they gathered that it was the one foretold by Balaam to indicate the King of the Jews."

Or again, it may be said with Augustine, in a sermon on the Epiphany (ccclxxiv), that "the Magi had received a revelation through the angels" that the star was a sign of the birth of Christ: and he thinks it probable that these were "good angels; since in adoring Christ they were seeking for salvation."

Or with Pope Leo, in a sermon on the Epiphany (xxxiv), that "besides the outward form which aroused the attention of their corporeal eyes, a more brilliant ray enlightened their minds with the light of faith." _______________________

SIXTH ARTICLE [III, Q. 36, Art. 6]

Whether Christ's Birth Was Made Known in a Becoming Order?

Objection 1: It would seem that Christ's birth was made known in an unbecoming order. For Christ's birth should have been made known to them first who were nearest to Christ, and who longed for Him most; according to Wis. 6:14: "She preventeth them that covet her, so that she first showeth herself unto them." But the righteous were nearest to Christ by faith, and longed most for His coming; whence it is written (Luke 2:25) of Simeon that "he was just and devout, waiting for the consolation of Israel." Therefore Christ's birth should have been made known to Simeon before the shepherds and Magi.

Obj. 2: Further, the Magi were the "first-fruits of the Gentiles," who were to believe in Christ. But first the "fulness of the Gentiles . . . come in" unto faith, and afterwards "all Israel" shall "be saved," as is written (Rom. 11:25). Therefore Christ's birth should have been made known to the Magi before the shepherds.

Obj. 3: Further, it is written (Matt. 2:16) that "Herod killed all the male children that were in Bethlehem, and in all the borders thereof, from two years old and under, according to the time which he had diligently inquired from the wise men": so that it seems that the Magi were two years in coming to Christ after His birth. It was therefore unbecoming that Christ should be made known to the Gentiles so long after His birth.

On the contrary, It is written (Dan. 2:21): "He changes time and ages." Consequently the time of the manifestation of Christ's birth seems to have been arranged in a suitable order.

I answer that, Christ's birth was first made known to the shepherds on the very day that He was born. For, as it is written (Luke 2:8, 15, 16): "There were in the same country shepherds watching, and keeping the night-watches over their flock . . . And it came to pass, after the angels departed from them into heaven they [Vulg.: 'the shepherds'] said one to another: Let us go over to Bethlehem . . . and they came with haste." Second in order were the Magi, who came to Christ on the thirteenth day after His birth, on which day is kept the feast of the Epiphany. For if they had come after a year, or even two years, they would not have found Him in Bethlehem, since it is written (Luke 2:39) that "after they had performed all things according to the law of the Lord"—that is to say, after they had offered up the Child Jesus in the Temple—"they returned into Galilee, to their city"—namely, "Nazareth." In the third place, it was made known in the Temple to the righteous on the fortieth day after His birth, as related by Luke (2:22).
