Augustine of Hippo
Catena Aurea · Lukasevangelium 20
And it came to pass, that on one of those days, as he taught the people in the temple, and preached the Gospel, the Chief Priests and the Scribes came upon him with the elders, And spake unto him, saying, Tell us, by what authority doest thou these things? or who is he that gave thee this authority? And he answered and said unto them, I will also ask you one thing; and answer me: The baptism of John, was it from heaven, or of men? And they reasoned with themselves, saying, If we shall say, From heaven; he will say, Why then believed ye him not? But and if we say, Of men; all the people will stone us: for they be persuaded that John was a prophet. And they answered, that they could not tell whence it was. And Jesus said unto them, Neither tell I you by what authority I do these things.
(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.
