Luke 20
Jesus' authority is questioned
On one of those days, as he was teaching the people in the temple and preaching the Good News, the priests and scribes came to him with the elders. They asked him, “Tell us: by what authority do you do these things? Or who is giving you this authority?”
He answered them, “I also will ask you one question. Tell me: the baptism of John, was it from heaven, or from men?”
They reasoned with themselves, saying, “If we say, ‘From heaven,’ he will say, ‘Why didn’t you believe him?’ But if we say, ‘From men,’ all the people will stone us, for they are persuaded that John was a prophet.” They answered that they didn’t know where it was from.
Jesus said to them, “Neither will I tell you by what authority I do these things.”
While Jesus is teaching in the temple, the chief priests, scribes and elders demand to know by what authority he acts. He replies with a question of his own: was John's baptism from heaven or from people? Fearing either answer, since the first would condemn their unbelief and the second would anger the crowd who believe John was a prophet, they say they do not know, and Jesus declines to answer them.
What does this mean?
"These things" probably refers to his action in the temple and his teaching there. "From heaven" is a reverent way of saying "from God."
Historical context
The chief priests controlled the temple and, with scribes and elders, led the council (Sanhedrin). Their fear that the people would stone them shows how popular John had been.
Why does it matter?
Jesus' counter-question links his authority with John's: both come from God, as Luke's opening chapters have shown. This begins a series of challenges in the temple (20:1–44), each of which Jesus turns back on his questioners.
