Matthew 2:1-2.
“When Jesus was born in Bethlehem of Judæa in the days of Herod the king, behold, there came wise men from the east to Jerusalem, saying, Where is He that is born King of the Jews? For we have seen His star in the east, and have come to worship Him.”
We have need of much wakefulness, and many prayers, that we may arrive at the interpretation of the passage now before us, and that we may learn who these wise men were, and whence they came, and how; and at whose persuasion, and what was the star. Or rather, if you will, let us first bring forward what the enemies of the truth say. Because the devil has blown upon them with so violent a blast, as even from this passage try to arm them against the words of truth.
What then do they allege? “Behold,” say they, “even when Christ was born a star appeared; which is a sign that astrology may be depended on.” How then, if He had His birth according to that law, did He put down astrology, and take away fate, and stop the mouths of demons, and cast out error, and overthrow all such sorcery?
And what moreover do the wise men learn from the star of itself? That He was King of the Jews? And yet He was not king of this kingdom; even as He said also to Pilate, “My kingdom is not of this world.” At any rate He made no display of this kind, for He had neither guards armed with spear or shield, nor horses, nor chariots of mules, nor any other such thing around Him; but He followed this life of meanness and poverty, carrying about with Him twelve men of mean estate.
And even if they knew Him to be a king, for what intent are they come? For surely this is not the business of astrology, to know from the stars who are born, but from the hour when men are born to predict what shall befall them: so it is said. But these were neither present with the mother in her pangs, nor did they know the time when He was born, neither did they, beginning at that moment, from the motion of the stars compute what was to happen: but conversely, having a long time before seen a star appear in their own country, they come to see Him that was born.
Which circumstance in itself would afford a still greater difficulty even than the former. For what reason induced them, or the hope of what benefits, to worship one who was king so far off? Why, had He been to reign over themselves, most assuredly not even so would the circumstance be capable of a reasonable account. To be sure, if He had been born in royal courts, and with His father, himself a king, present by Him, any one would naturally say, that they, from a wish to pay court to the father, had worshipped the child that was born, and in this way were laying up for themselves beforehand much ground of patronage. But now when they did not so much as expect Him to be their own king, but of a strange nation, far distant from their country, neither seeing Him as yet grown to manhood; wherefore do they set forth on so long a journey, and offer gifts, and this when dangers were sure to beset their whole proceeding? For both Herod, when he heard it, was exceedingly troubled, and the whole people was confounded on being told of these things by them.
“But these men did not foresee this.” Nay, this is not reasonable. For let them have been ever so foolish, of this they could not be ignorant, that when they came to a city under a king, and proclaimed such things as these, and set forth another king besides him who then reigned, they must needs be bringing down on themselves a thousand deaths.
