Matthew 26:8

And whence had they this thought? They used to hear their Master saying, "I will have mercy, and not sacrifice," and blaming the Jews, because they omitted the weightier matters, judgment, and mercy, and faith, and discoursing much on the mount concerning almsgiving, and from these things they inferred with themselves, and reasoned, that if He accepts not whole burnt offerings, neither the ancient worship, much more will He not accept the anointing of oil.

I know that some raise a cavil here, because John says that Judas alone was grieved because he had the bag, and was a thief from the beginning; but Matthew, that all the disciples were sorrowful. These know not the figure syllepsis, by which one name is put for many, and many for one; as Paul in the Epistle to the Hebrews says, They were sawn asunder, when it is thought that one only, Esaias namely, was so. (Heb. 11:37.)

(de Cons. Ev. ii. 79.) We may however understand that the other disciples thought or said the same, or that they assented to what Judas said, and thus Matthew and Mark have described their common consent. But Judas said it because he was a thief, the others out of their care for the poor; and John desired to mention it only in the case of him whose thievish propensity he thought ought to be recorded.

Some one may perhaps think that there are four different women of whom the Evangelists have written, but I rather agree with those who think that they are only three; one of whom Matthew and Mark wrote, one of whom Luke, another of whom John. Matthew and Mark relate that this was done in the house of Simon the leper; but John says that Jesus came to a house where Lazarus was; and that not Simon, but Mary and Martha served. Further, according to John, six days before the Passover, He came to Bethany where Mary and Martha made Him a supper. But here it is in the house of Simon the leper, and two days before the Passover. And in Matthew and Mark, it is the disciples that have indignation with a good intent; in John, Judas alone with intent to steal; in Luke, no one finds fault. Oil is throughout Scripture put for the work of mercy, with which the lamp of the word is fed; or for doctrine, the hearing of which sustains the word of faith when once kindled. All with which men anoint is comprehensively called oil; and one kind of oil is unguent, and one kind of unguent is precious. So all righteous acts are called good works; and of good works there is one kind which we do for, or to, men; another which we do for, or to, God. And this likewise that we do for God, in part only advances the good of men, in part, the glory of God. For example, one does a kindness to a man out of feelings of natural righteousness, not for God's sake, as the Gentiles sometime did; such a work is common oil of no fine savour, yet is it acceptable to God, forasmuch, as Peter says in Clement, the good works that the unbelievers do, profit them in this world, but avail not to gain them eternal life in another. They who do the same for God's sake, profit thereby not in this world only but in the next also, and that they do is ointment of good savour. Another sort is that done for the good of men, as alms, and the like. He who does this to Christians, anoints the Lord's feet, for they are the Lord's feet; and this penitents are most found to do for remission of their sins. He who devotes himself to chastity, and continues in fastings and prayers, and other things which conduce to God's glory only, this is the ointment which anoints the Lord's head, and with whose odour the whole Church is filled; this is the work meet not for penitents, but for the perfect, or the doctrine which is necessary for men; but the acknowledgment of the faith which belongs to God alone, is the ointment with which the head of Christ is anointed, with which we are buried together with Christ by baptism into death. (Rom. 6:4.)

In this woman is prefigured the people of the Gentiles, who gave glory to God in Christ's passion; for she anointed His head, but the head of Christ is God, and ointment is the fruit of good works. But the disciples, anxious for the salvation of Israel, say that this ought to have been sold for the use of the poor; designating by a prophetic instinct the Jews, who lacked faith, by the name of the poor.
