Catena Aurea on Matthew 26:6–13: John Chrysostom

And in this way it may be the same in the three Evangelists, Matthew, Mark, and Luke. And not without good reason does the Evangelist mention Simon’s leprosy, to shew what gave this woman confidence to come to Christ. The leprosy was an unclean disease; when then she saw that Jesus had healed the man with whom He now lodged, she trusted that He could also cleanse the uncleanness of her soul; and so whereas other women came to Christ to be healed in their bodies, she came only for the honour and the healing of her soul, having nothing diseased in her body; and for this she is worthy our highest admiration. But she in John is a different woman, the wonderful sister of Lazarus.
