Mark 5:28

For she said, If I shall touch but His garment, I shall be whole. Matthew (Matthew 9:20), instead of garment, has the hem of His garment. This hem was a fringe of threads attached to the bottom of the robe, of a hyacinth or violet colour, which God commanded the Jews to wear, that it might put them continually in mind of God's precepts and of heaven itself. This Christ wore, according to the law, as a mark that He belonged to the Jewish race and religion.

There is here an example and proof of the use and efficacy of holy relics. For of such a nature was the hem or fringe of Christ which healed her that had the issue of blood. Calvin replies that the woman was superstitious, and that a certain amount of superstition was mingled with what she did. But Christ and Mark refute this; for they ascribe her healing not to superstition, but to her faith, and commend her for it. For in the 30th verse it is said, And Jesus, immediately knowing in Himself that virtue was gone out from Him (de illo), i.e., from (de) His fringe. And 34, Daughter, thy faith hath saved thee, go in peace. Rightly says S. Hilary, "Like as the Author of nature has given to a magnet the power of attracting iron, so did Christ give to His garment the power of healing her who touched in faith." And if it were so with a garment, how much more with the Eucharist? Hence S. Gorgonia was healed of a severe disease by touching the Eucharist. (See Nazianzen, Orat. 11.) So, too, was S. Catherine of Sienna, and many others. (See Salmeron, tom. 6, tract. 15.)

Tropologically : The issue of blood, says Bede, is fleshly delight, as gluttony, luxury. The most pure flesh of Christ heals these when piously received in the Eucharist. Ver. 30. And Jesus... had gone out of Him, and had healed her; not as if any quality had gone out from Christ's hem, or as if this virtue had gone from place to place, from the hem into the woman who had the issue of blood, but by reason of the effect which it produced in the woman. For the virtue abiding in Christ wrought the effect of healing in the woman. Like as, saith Theophylact, the learning of doctors is said to be communicated to their disciples, when, nevertheless, the learning itself remains in the doctors, and produces its effect only, that is, a like knowledge in the disciples.

Observe, this virtue of healing and working miracles conferred by the Word upon the humanity of Christ, was not a physical quality. For that would have been infinite, as having divine and infinite efficacy, of which the humanity of Christ was not capable, being created. But it was a moral quality, that is to say, an instrumental virtue. For the humanity of Christ did these things as an instrument of the divinity.

Who hath touched My garments? Christ asks this question, says Bede, that the healing which He had given to the woman, being declared and made known, might advance in many the virtue of faith, and draw them to believe in Christ.
