Verily, verily, I say unto you, We speak what we do know, and testify what we have seen; and you receive not our witness.
All Commentaries on John 3:11 Go To John 3
Cyril of Alexandria
AD 444
Verily, verily, I say unto thee, We speak that we do know and testify that we have seen.
He finds the man careless of learning and exceedingly uninstructed and, by reason of his great grossness of mind, utterly unable to be led unto the comprehension of Divine doctrines, albeit many words had been expended with manifold examples. Whence letting alone, as was fitting, accurate explanation, He at length advises him to accept in simple faith, what he cannot understand. He testifies that Himself knows clearly what He saith, by the illustriousness of His Person shewing that yet to gainsay is most dangerous. For it was not likely that Nicodemus would forget, who had affirmed that he knew it of our Saviour Christ, that He was a Teacher come from God. But to resist one who is from God and God, how would it not be fraught with peril? for the thing is clearly a fighting with God. But hence we ought to know, who have authority to teach, that for those just come to the faith, faith in simple arguments is better than any deep reasoning, and more elaborate explanation. And Paul also used to feed with milk some, not yet able to bear stronger meats. And the most wise Solomon again somewhere says to us, Thou shalt wisely know the souls of thy flock, meaning that we should not set before those who come to us the word of doctrine indiscriminately, but fitly adapted to the measure of each.
