201 One day, as he was teaching the people in the temple and telling the good news, the chief priests and the scribes came with the elders 2 and said to him, "Tell us, by what authority are you doing these things? Who is it who gave you this authority?" 3 He answered them, "I will also ask you a question, and you tell me: 4 Did the baptism of John come from heaven, or was it of human origin?" 5 They discussed it with one another, saying, "If we say, "From heaven,' he will say, "Why did you not believe him?' 6 But if we say, "Of human origin,' all the people will stone us; for they are convinced that John was a prophet." 7 So they answered that they did not know 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.
