Jerome
Catena Aurea · Matthäusevangelium 21
And when he was come into the temple, the Chief Priests and the elders of the people came unto him as he was teaching, and said, By what authority doest thou these things? and who gave thee this authority? And Jesus answered and said unto them, I also will ask you one thing, which if ye tell me, I in like wise will tell you by what authority I do these things. The baptism of John, whence was it? from heaven, or of men? And they reasoned with themselves, saying, If we shall say, From heaven; he will say unto us, Why did ye not then believe him? But if we shall say, Of men; we fear the people; for all hold John as a prophet. And they answered Jesus, and said, We cannot tell. And he said unto them, Neither tell I you by what authority I do these things.
Or in these words they urge the same cavil as above, when they said, He casteth out demons through Beelzebub the Prince of the demons. (Mat. 12:24.) For when they say, By what authority doest thou these things? they doubt concerning the power of God, and would have it understood that the things He does are of the Devil. But when they add, Who gave thee this authority? they most clearly deny the Son of God, whom they suppose to work miracles, not by His own, but by others’ strength. The Lord could have confuted the calumny of His tempters by a simple answer, but He put a question to them of such skilful contrivance, that they must be condemned either by their silence or their knowledge; Jesus answered and said unto them, I also will ask you one question.
