Luke 7:37

And behold, a woman who was in the city, a sinner; and when she knew that he was sitting at meat in the Pharisee's house, she brought an alabaster cruse of ointment and standing behind at his feet weeping, she began to wet his feet with her tears, and wiped them with the hair of her head, and kissed his feet, and anointed them with the ointment.

It is hyper-ridiculous to equate this with the anointing by the devout Mary, as recorded in the other Gospels. This person was a "sinner," and her knowledge of what was going on in this Pharisee's house speaks volumes about the Pharisee. Her free access to his house shows some affinity between them, although it did not extend so far as a common attitude toward Jesus, whom the Pharisee dishonored, and whom the woman honored. This unfortunate daughter of Israel had fallen into a life of sin, but she recognized in Jesus a holiness and love which opened up the fountain of her tears falling inadvertently upon his feet, a fault (as she viewed it) which was quickly corrected by her wiping them with her hair, and anointing them with the precious ointment. Her kisses, lavished upon his feet, were a further expression of her love for the Son of God.
