Eusebius of Caesarea
Catena Aurea · Lukasevangelium 20
And it came to pass, that on one of those days, as he taught the people in the temple, and preached the Gospel, the Chief Priests and the Scribes came upon him with the elders, And spake unto him, saying, Tell us, by what authority doest thou these things? or who is he that gave thee this authority? And he answered and said unto them, I will also ask you one thing; and answer me: The baptism of John, was it from heaven, or of men? And they reasoned with themselves, saying, If we shall say, From heaven; he will say, Why then believed ye him not? But and if we say, Of men; all the people will stone us: for they be persuaded that John was a prophet. And they answered, that they could not tell whence it was. And Jesus said unto them, Neither tell I you by what authority I do these things.
But the rulers who should have been struck with wonder at one who taught such heavenly doctrines, and have been convinced by His words and deeds that this was the same Christ whom the Prophets had foretold, came to hinder Him, so helping onward the destruction of the people. For it follows, And spake unto him, saying, Tell us, by what authority doest thou these things? &c. As if he said; By the law of Moses, those only who are sprung from the blood of Levi have authority to teach, and power over the sacred buildings. But Thou who art of the line of Judah usurpest the offices assigned to us. Whereas, O Pharisee, if thou hadst known the Scriptures, thou wouldest have called to mind that this is the Priest after the order of Melchisedec, who offers to God them that believe on Him by that worship which is above the law. Why then art thou troubled. He cast out of the sacred house things which seemed necessary for the sacrifices of the law, because He calls us by faith to the true righteousness.
