Augustine of Hippo — as excerpted in the Catena Aurea on John 6:1-14

“(Tr. xxiv. s. 1, 2) But let us reflect a little here. Forasmuch as the Divine Substance is not visible to the eye, and the miracles of the divine government of the world, and ordering of the whole creation, are overlooked in consequence of their constancy; God has reserved to Himself acts, beside the established course and order of nature, to do at suitable times; in order that those who overlooked the daily course of nature, might be roused to wonder by the sight of what was different from, though not at all greater, than what they were used to. The government of the world is a greater miracle, than the satisfying the hunger of five thousand with five loaves; and yet no one wonders at this: the former excited wonder; not from any real superiority in it, but because it was uncommon. But it would be wrong to gather no more than this from Christ’s miracles: for, the Lord who is on the mounte, and the Word of God which is on high, the same is no humble person to be lightly passed over, but we must look up to Him reverently.”
