Jesus answered and said unto them,
This is the work of God, that you believe on him whom he has sent.

Cyril of Alexandria
AD 444
Most severely doth the Lord, even though secretly as yet and obscurely, attack the folly of the questioners. For one would suppose, looking merely at the simple meaning of the words, that Jesus was commanding them nothing else, save to believe on Him: but on examining the intent of the words, he will see that they refer to something else. For full well does He arrange His discourse suitably to the folly of the questioners. For they, as though they learnt sufficiently through the Law how to work what was well-pleasing to God, blasphemously neglect the teaching of our Saviour, saying, what shall we do, that we might work the work of God? But it was necessary that He should shew them, that they were still very far removed from the worship most pleasing unto God, and that they knew no whit of the true good things, who cleaving to the letter of the law, have their mind full of mere types and forms. Therefore with some great emphasis does He say, opposing the fruit of faith to the worship of the Law, This is the work of God that ye believe on Him whom HE sent. That is, it is not what YE supposed (He says) looking to the types alone; but know ye, even though ye will not learn it, that the Lawgiver took no pleasure in your sacrifices of oxen, nor needest thou to sacrifice sheep, as though God willed and required this. For what is frankincense, though it curl in the air in fragrant steam, what will the he-goat profit (saith He) and the costly offerings of cinnamon? God eateth not the flesh of bulls, nor yet drinketh He the blood of goats: He knoweth all the fowls of the Heaven, and the wild beasts of the field are with Him. But He hath hated and despised your feasts, and will not smell in your solemn assemblies, as Himself saith: nor spake He unto your fathers concerning whole burnt offerings or sacrifices. Therefore not this is the tvork of God, but rather that, that ye should believe on Him whom He sent. For of a truth better than the legal and typical worship is the salvation through faith and the grace that justifieth than the commandment that condemneth.
The work then of the pious soul is faith to Christ-ward, and more excellent far the zeal for to become wise in the knowledge of Him, than the cleaving to the typical shadows. You will marvel also at this besides: for whereas Christ was wont to take no notice of those who questioned Him, tempting Him, He answers this for the present economically (even though He knew that they would be nothing profited) to their own condemnation, as He says elsewhere too, If I had not come and spoken unto them, they had not had sin; but now they have no cloke for their sin.
