"A certain man had two sons; and he came to the first, and said, Son, go work to day in my vineyard. He answered and said, I will not: but afterward he repented, and went. And he came to the second, and said likewise. And he answered and said, I go, sir: and went not. Whether of them twain did the will of his father? They say unto him, The first" Matthew 21:28-31.

They were challenging the source of His authority when He spoke the parable sited above. By their own words the church leaders condemned themselves.
