And I knew him not: but that he should be made manifest to Israel, therefore am I come baptizing with water.
All Commentaries on John 1:31 Go To John 1
Cyril of Alexandria
AD 444
He that leaped in the depth of the womb of his mother at the voice of the Holy Virgin while yet bearing the Lord, prophet before the travail-pang, disciple in the womb, says of the Saviour, I knew Him not, and says truly, for he does not lie. For God knows all things of Himself and untaught, but the creature, by being taught. For the Spirit indwelling in the Saints, fulfils what is lacking, and gives to human nature His Own good, I mean, knowledge of things to come, and of the hidden mysteries. Therefore the holy Baptist saying that he does not know the Lord, will by no means speak untruly, in regard of the property of human nature, and the measure befitting the creature, but will attribute the knowledge of all things to God Alone, Who through the Holy Ghost enlighteneth man to the apprehension of hidden things. And very profitably doth he say that of himself he knew not Christ, but is come for that very purpose, to make Him manifest to Israel, that he may not seem to run of his own accord to bear testimony, nor be thought by any the minister of his own will, but the worker of the Divine dispensation, the minister of the Counsel from above revealing to him the Lamb Which taketh away the sin of the world.
In order therefore that the Jews may the more easily come to believe on our Saviour Christ, and may have the most worthy conception of Him, he says that having not known Him, he knows Him, that they may understand then at length God Who revealed Him, and awestruck at the judgment from above, may receive his word concerning Him, and, seeing the servant so great, may proportionally estimate the Dignity of the Master. For his saying, that he was come to make Him manifest to Israel, how does it not denote the care belonging to a servant?
