Luke 20:2

Or when they say, By what authority doest thou these things? they doubt concerning the power of God, and wish it to be understood that of the devil He doeth this. Adding moreover, And who is he that gave thee this authority? Most plainly do they deny the Son of God when they think that not by His own power but another's He doeth miracles.

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.
