Matthew 16:17

Blessed art thou, Simon Bar-jona. — Looking to the reality of our Lord’s human nature, its capacity for wonder (Mark 6:6; Luke 7:9), anger (Mark 3:5), sorrow (John 11:35; Luke 19:41), and other emotions, it is not over-bold to recognise in these words something like a tone of exalted joy. It is the first direct personal beatitude pronounced by Him; and, as such, presents a marked contrast to the rebukes which had been addressed to Peter, as to the others, as being “without understanding,” “of little faith,” with “their heart yet hardened.” Here, then, He had found at last the clear, unshaken, unwavering faith which was the indispensable condition for the manifestation of His kingdom as a visible society upon earth. The beatitude is solemnised (as in John 1:42) by the full utterance of the name which the disciple had borne before he was called by the new name of Cephas, or Peter, to the work of an Apostle. He was to distinguish between the old natural and the new supernatural life. (Comp. John 21:15.)

Flesh and blood hath not revealed it unto thee. — Better, It was not flesh and blood that revealed. The words are used in their common Hebrew meaning (as in John 1:13; 1 Corinthians 15:50; Ephesians 6:12) for human nature, human agency, in all their manifold forms. The disciple had received the faith which he now professed, not through popular rumours, not through the teaching of scribes, but by a revelation from the Father. He was led, in the strictest sense of the words, through the veil of our Lord’s human nature to recognise the divine.
