Matthew 26:12

The ointment with an agreeable odor represents what the faithful do for God. This very work of the faithful of God, which is ointment, becomes something else for the good of humanity—for instance, almsgiving, visits to the sick, welcoming strangers, humility, gentleness, pardon, and so forth. These are things that benefit human beings. He who does them to Christians anoints the Lord's feet with ointment, for they are the Lord's feet with which he will always walk.… This is the ointment which also anoints Christ's head and flows down over his whole body, that is, it pours down on the whole church. This is the precious ointment that fills the whole house with its odor, that is, the church of Christ. This is the work that is proper not for penitents but for the preeminently holy people. Certainly the teaching necessary for people which feeds those who are poor in spiritually good things or those who are perhaps weak in avoiding sin—this is the plain ointment with which the Lord's feet are anointed. However, the knowledge of the true faith which pertains to God alone—this is the precious ointment that anoints God, Christ's head.

The Lord answers that there is abundant time in which they may show their care for the poor, but that salvation cannot be extended to the Gentiles but by obedience to His command, if, that is, by the pouring out of this woman's ointment they are buried together with Him, because regeneration can only be given to those who are dead in the profession of baptism.

It was the custom among this people to embalm the bodies of the dead with divers spices, to the end that they might be kept from corruption as long as possible. And as this woman was desirous of embalming the Lord's dead Body, and would not be able because she would be anticipated by His resurrection, it was therefore arranged by Divine Providence that she should anoint the Lord's living Body. This then is what He says, In that she hath poured, that is, By anointing My living Body she shows forth My death and burial.

But though they thus thought, He knowing her intention suffers her. For indeed great was her reverence, and unspeakable her zeal; wherefore of this exceeding condescension, He permitted the oil to be poured even on His head. For if He refused not to become man, and to be borne in the womb, and to be fed at the breast, why marvellest thou, if He doth not utterly reject this? For like as the Father suffered a savor of meat, and smoke, even so did He the harlot, accepting, as I have already said, her intention. For Jacob too anointed a pillar to God, and oil was offered in the sacrifices, and the priests were anointed with ointment. But the disciples not knowing her purpose found fault unseasonably, and by the things they laid to her charge, they show the woman's munificence. For saying, that it might have been sold for three hundred pence, they showed how much this woman had spent on the ointment, and how great generosity she had manifested. Wherefore He also rebuked them, saying, "Why trouble ye the woman?" And He adds a reason, as it was His will again to put them in mind of His passion, "For she did it," He said, "for my burial." And another reason. "For ye have the poor always with you, but me ye have not always;" and, "Wheresoever the gospel shall be preached, that shall be told also which this woman hath done." Seest thou how again He declares beforehand the going forth unto the Gentiles, in this way also consoling them for His death, if after the cross His power was so to shine forth, that the Gospel should be spread abroad in every part of the earth. Who then is so wretched as to set his face against so much truth? For lo! […]

For in that she hath poured this myrrh on My Body, she did it for My burial. Verily I say unto you, Wheresoever this Gospel shall be preached in the whole world, there shall also this, that this woman hath done, be told for a …
