Luke 20:1

(de con. Ev. l. ii. c. 69.) Having related the casting out of those that bought and sold in the temple, Luke omits Christ's going to Bethany and His return again to the city, and the circumstances of the fig-tree, and the answer which was made to the astonished disciples, concerning the power of faith. And having omitted all these, as he does not, like Mark, pursue the events of each day in order, he commences with these words, And it came to pass, that on one of those days; by which we may understand that day on which Matthew and Mark related that event to have taken place.

And it happened on one of the days, as he was teaching the people in the temple and proclaiming the gospel, the chief priests and the scribes with the elders came to him, and they said to him, "Tell us by what authority you do these things." In different ways, they construct the same slander as above, when they said, "In Beelzebul, the prince of demons, he casts out demons" (Luke XI). For when they say, "By what authority do you do these things?" they doubt the authority of God, and they want it to be understood that it is by the power of the devil that he does these things. Adding also:

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.
