6 Let us then also follow the magi, let us separate ourselves from our barbarian customs, and make our distance therefrom great, that we may see Christ, since they too, had they not been far from their own country, would have missed seeing Him. Let us depart from the things of earth. For so the wise men, while they were in Persia, saw but the star, but after they had departed from Persia, they beheld the Sun of Righteousness. Or rather, they would not have seen so much as the star, unless they had readily risen up from thence. Let us then also rise up; though all men be troubled, let us run to the house of the young Child; though kings, though nations, though tyrants interrupt this our path, let not our desire pass away. For so shall we thoroughly repel all the dangers that beset us. Since these too, except they had seen the young Child, would not have escaped their danger from the king. Before seeing the young Child, fears and dangers and troubles pressed upon them from every side; but after the adoration, it is calm and security; and no longer a star but an angel receives them, having become priests from the act of adoration; for we see that they offered gifts also.
Therefore likewise leave the Jewish people, the troubled city, the blood-thirsty tyrant, the pomp of the world, and hasten to Bethlehem, where is the house of the spiritual Bread. For though you be a shepherd, and come hither, you will behold the young Child in an inn: though you be a king, and approach not here, your purple robe will profit you nothing; though you be one of the wise men, this will be no hindrance to you; only let your coming be to honor and adore, not to spurn the Son of God; only do this with trembling and joy: for it is possible for both of these to concur in one.
But take heed that you be not like Herod, and say, “that I may come and worship Him,” and when you have come, be minded to slay Him. For him do they resemble, who partake of the mysteries unworthily: it being said, that such a one “shall be guilty of the Body and Blood of the Lord.” Yes; for they have in themselves the tyrant who is grieved at Christ's kingdom, him that is more wicked than Herod of old, even Mammon. For he would fain have the dominion, and sends them that are his own to worship in appearance, but slaying while they worship. Let us fear then, lest at any time, while we have the appearance of suppliants and worshippers, we should in deed show forth the contrary.
And let us cast everything out of our hands when we are to worship; though it be gold that we have, let us offer it unto him and not bury it. For if those barbarians then offered it for honor, what will become of you, not giving even to Him that has need? If those men journeyed so far to see Him newly born, what sort of excuse will you have, not going out of your way one alley's length, that you may visit Him sick or in bonds? And yet when they are sick or in bonds, even our enemies have our pity; yours is denied even to your Benefactor and Lord. And they offered gold, you hardly give bread. They saw the star and were glad, you, seeing Christ Himself a stranger and naked, are not moved.
For which of you, for Christ's sake, has made so long a pilgrimage, you that have received countless benefits, as these barbarians, or rather, these wiser than the wisest philosophers? And why say I, so long a journey? Nay, many of our women are so delicate, that they go not over so much as one crossing of the streets to behold Him on the spiritual manger, unless they can have mules to draw them. And others being able to walk, yet prefer to their attendance here, some a crowd of worldly business, some the theatres. Whereas the barbarians accomplished so great a journey for His sake, before seeing Him; you do not emulate them even after you have seen Him, but forsake Him after seeing Him, and run to see the stage player. (For I touch again on the same subjects, as I did also of late.) And seeing Christ lying in the manger, you leave Him, that you may see women on the stage.
