Matt. II. 2.
“And when they had come into the house, they saw the young Child with Mary His mother.”
How then says Luke, that He was lying in the manger? Because at the birth indeed she presently laid Him there (for, as was not unlikely, in that large assemblage for the taxing, they could find no house; which Luke also signifies, by saying, “Because there was no room, she laid Him” there); but afterwards she took Him up, and held Him on her knees. For no sooner was she arrived at Bethlehem than she brought her pangs to an end, that you may thence also learn the whole dispensation, and that these things were not done at random, or by chance, but that they all were in course of accomplishment, according to some Divine foreknowledge, and prophetic order.
But what was it that induced them to worship? For neither was the Virgin conspicuous, nor the house distinguished, nor was any other of the things which they saw apt to amaze or attract them. Yet they not only worship, but also “open their treasures,” and “offer gifts;” and gifts, not as to a man, but as to God. For the frankincense and the myrrh were a symbol of this. What then was their inducement? That which wrought upon them to set out from home and to come so long a journey; and this was both the star, and the illumination wrought of God in their mind, guiding them little by little to the more perfect knowledge. For, surely, had it not been so, all that was in sight being ordinary, they would not have shown so great honor. Therefore none of the outward circumstances was great in that instance, but it was a manger, and a shed, and a mother in poor estate; to set before your eyes, naked and bare, those wise men's love of wisdom, and to prove to you, that not as mere man they approached Him, but as a God, and Benefactor. Wherefore neither were they offended by ought of what they saw outwardly, but even worshipped, and brought gifts; gifts not only free from Judaical grossness, in that they sacrificed not sheep and calves, but also coming near to the self-devotion of the Church, for it was knowledge and obedience and love that they offered unto Him.
“And being warned of God in a dream that they should not return unto Herod, they departed into their own country another way.”
See from this also their faith, how they were not offended, but are docile, and considerate; neither are they troubled, nor reason with themselves, saying, “And yet, if this Child be great, and has any might, what need of flight, and of a clandestine retreat? And wherefore can it be, that when we have come openly and with boldness, and have stood against so great a people, and against a king's madness, the angel sends us out of the city as runaways and fugitives?” But none of these things did they either say or think. For this most especially belongs to faith, not to seek an account of what is enjoined, but merely to obey the commandments laid upon us.
2. “And when they were departed, behold, an angel appears to Joseph in a dream, saying, Arise, and take the young Child and His mother, and flee into Egypt.”
There is something here worth inquiring into, both touching the magi, and touching the Child; for if even they were not troubled, but received all with faith, it is worthy of examination on our part, why they and the young Child are not preserved, continuing there, but they as fugitives go into Persia, He with His mother into Egypt. But what? Should He have fallen into the hands of Herod, and having fallen, not have been cut off? Nay, He would not have been thought to have taken flesh upon Him; the greatness of the Economy would not have been believed.
For if, while these things are taking place, and many circumstances are being ordered mysteriously after the manner of men, some have dared to say that His assumption of our flesh is a fable; in what degree of impiety would they not have been wrecked had He done all in a manner becoming His Godhead, and according to His own power?
As to the wise men, He sends them off quickly, at once both commissioning them as teachers to the land of the Persians, and at the same time intercepting the madness of the king, that he might learn that he was attempting things impossible, and might quench his wrath, and desist from this his vain labor. For not alone openly to subdue His enemies, but also to deceive them with ease, is worthy of His power. Thus, for example, He deceived the Egyptians also in the case of the Jews, and having power to transfer their wealth openly into the hands of the Hebrews, He bids them do this secretly and with craft; and this surely, not less than the other miracles, made Him an object of terror to His enemies. At least, they of Ascalon, and all the rest, when they had taken the ark, and being smitten, did after that devise their countrymen not to fight, nor to set themselves against Him, with the other miracles brought this also forward, saying, “Wherefore harden ye your hearts, as Egypt and Pharaoh hardened? When He had mocked them, did He not after that send forth His people, and they departed?” Now this they said, as accounting this fresh one not inferior to those other signs that had been done openly, towards the demonstration of His power, and of His greatness. And the like ensued on this occasion too; a thing sufficient to astonish the tyrant. For consider what it was natural for Herod to feel, and how his very breath would be stopped, deceived as he was by the wise men, and thus laughed to scorn. For what, if he did not become better? It is not His fault, who marvellously ordered all this, but it is the excess of Herod's madness, not yielding even to those things which had virtue to have persuaded him, and deterred him from his wickedness, but going on still further, to receive a yet sharper punishment for folly so great.
