v. 36 — And Who is He, Lord, saith he, that I may believe on Him?
Commentary on the Gospel according to John · St Cyril of Alexandria
The soul furnished with sound reason, diligently seeking the word of truth with the eyes of the understanding free, without embarrassment makes straight for it like a ship going into port, and obtains its advantages by a chase without fatigue. And again the man who had been blind will be a proof of what has been said. For when he had already by many arguments and reasonings admired the mystery concerning Christ, and moreover had been struck with astonishment at His unspeakable might, which had been experienced not by any other but by himself in himself, he is found thus ready to believe and without delay proceeds to do so. For see, see, he earnestly asks upon whom he should fasten that faith which had been already built up within him. For this alone was lacking to him, and he was previously prepared for it, as we have said.
CyrJn 6.36.1
