Mark 6:52

"We have but five loaves, and two fishes." Wherefore Mark also saith, "They understood not the saying, for their heart was hardened." They continuing therefore to crawl on the ground, then at length He brings in His own part, and saith, "Bring them hither to me." For although the place be desert, yet He that feeds the world is here; and although the time be now past, yet He that is not subject to time is discoursing with you.

Great indeed is the miracle of our Lord's walking on the sea, but the tempest and the contrary wind were there as well, to make the miracle greater. For the Apostles, not understanding from the miracle of the five loaves the power of Christ, now more fully knew it from the miracle of the sea. Wherefore it goes on, And they were sore amazed in themselves. For they understood not concerning the loaves.

(ubi sup.) The disciples indeed, who were still carnal, were amazed at the greatness of His virtue, they could not yet however recognise in Him the truth of the Divine Majesty. Wherefore it goes on, For their hearts were hardened. But mystically, the toil of the disciples in rowing, and the contrary wind, mark out the labours of the Holy Church, who amidst the beating waves of the world, and the blasts of unclean spirits, strives to reach the repose of her celestial country. And well is it said that the ship was in the midst of the sea, and He alone on land, for sometimes the Church is afflicted by a pressure from the Gentiles so overwhelming, that her Redeemer seems to have entirely deserted her. But the Lord sees His own, toiling on the sea, for, lest they faint in tribulations, He strengthens them by the look of His love, and sometimes frees them by a visible assistance. Further, in the fourth watch He came to them as daylight approached, for when man lifts up his mind to the light of guidance from on high, the Lord will be with him, and the dangers of temptations will be laid asleep.
