201 And it came about on one of those days, when he was teaching the people in the Temple and preaching the good news, 2 That the chief priests and the scribes and the rulers of the people came to him and said, Make clear to us by what authority you do these things and who gave you this authority. 3 And in answer he said to them, I will put a question to you, and do you give me an answer: 4 The baptism of John, was it from heaven or of men? 5 And they said among themselves, If we say, From heaven; he will say, Why did you not have faith in him? 6 But if we say, Of men; we will be stoned by the people, for they are certain that John was a prophet. 7 And they made answer that they had no idea where it came from.

Commentary on Luke 20:1-8
(Read Luke 20:1-8)
Men often pretend to examine the evidences of revelation, and the truth of the gospel, when only seeking excuses for their own unbelief and disobedience. Christ answered these priests and scribes with a plain question about the baptism of John, which the common people could answer. They all knew it was from heaven, nothing in it had an earthly tendency. Those that bury the knowledge they have, are justly denied further knowledge. It was just with Christ to refuse to give account of his authority, to those who knew the baptism of John to be from heaven, yet would not believe in him, nor own their knowledge.
