There seems then much likeness and some connection about the woman in the four Evangelists. Yet I would say to those who think that all wrote of the same woman, "Do you think that the very same woman who poured precious ointment on Jesus' head, as Matthew and Mark have related, also anointed his feet with ointment (or "myrrh," "myrrha") as Luke and John have related?But it is not possible that the Evangelists should have contradicted one another in relating about the same woman, since they were perfected in the same understanding and the same spirit and the same mind, and they had been seeking to minister to the welfare of the church. But if anyone thinks it is the same woman in Luke and John, let him tell us if Mary was the woman who is said in Luke to have been a sinner in a city who, learning that Jesus had sat down to meet in a Pharisee's house, brought an alabaster box of ointment and stood behind his feet weeping, washing his feet with her tears.
It is incredible that Mary, whom Jesus loved, the sister of Martha, who had chosen the better portion, should be said to have been a sinner in the city. And the woman who, according to Matthew and Mark, poured precious ointment on Jesus' head is not actually written to have been a sinner. But she who according to Luke is described as a sinner did not dare to reach to Christ's head but washed his feet with her tears—as if scarcely worthy of his very feet—from sorrow that brought about sincere repentance with salvation.
The woman in Luke wails and weeps much so that she may wash Jesus' feet. But she, who according to John is Mary, is introduced neither as a sinner nor as weeping. Perhaps then one will say that four different women are recorded by the Evangelists. But I rather agree that there were three. There was the one of whom Matthew and Mark wrote in complete agreement. There was also the woman of whom Luke wrote, while John wrote of yet another, differing from the other woman not only in what is written about the ointment but also because Jesus loved Mary and Martha—although she also is related to have been at Bethany like the woman in Matthew and Mark.
