Song of Solomon 1:3

And as we are examining his name, the seal of all we have said may be found in the oracle of Solomon the wisest of the wise, where he says in the Song of Songs: "Your name is as ointment poured forth." Solomon, being supplied with divine wisdom, and thought worthy of more mystical revelations about Christ and his church, and speaking of him as heavenly bridegroom and her as bride, speaks as if to [Christ] and says, "Your name, O Bridegroom, is ointment," and not simply ointment, but "ointment poured forth." And what name could be more suggestive of ointment poured forth than the name of Christ? For there could be no Christ, and no name of Christ, unless ointment had been poured forth. And in what has gone before I have shown of what nature the ointment was with which Christ was anointed.

Like ointment upon the head, which runs down upon the beard, the beard of Aaron. Oh, if there were time for us to discuss each detail, a day could not suffice us. We read in Exodus how the priestly ointment is prepared; then we read how there was another ointment, with which the kings were anointed. There was also another ointment with which the prophets were anointed. And why do I say more? All the ointments had their own distinctions and mysteries. Do we marvel about holy persons? A leper, after he has been cleansed, after he has been sprinkled with hyssop and with the blood of a bird, and one bird is released into the wilderness, he too has his own proper ointment. Nothing is sanctified except through ointment. Therefore the young maidens also say in the Song of Songs: "Thy name is ointment poured out. After thee we will run in the fragrance of thy ointments."

After this, you went up to the priest. Consider what followed. Was it not that of which David speaks: "Like the ointment upon the head, which went down to the beard, even Aaron's beard"? This is the ointment of which Solomon, too, says, "Your name is ointment poured out, therefore have the maidens loved you and drawn you." How many souls regenerated this day have loved you, Lord Jesus, and have said, "Draw us after you, we are running after the odor of your garments," that they might drink in the odor of your resurrection.Consider now why this is done, for "the eyes of a wise man are in his head." Therefore the ointment flows down to the beard, that is to say, to the beauty of youth; and therefore, Aaron's beard, that we, too, may become a chosen race, priestly and precious, for we are all anointed with spiritual grace for a share in the kingdom of God and in the priesthood.
