Gospel text (Mt 21,23-27): Jesus had entered the Temple and was teaching when the chief priests, the teachers of the Law and the Jewish authorities came to him and asked, «What authority have you to act like this? Who gave you authority to do all this?».Jesus answered them, «I will also ask you a question, only one. And if you give me an answer, then I will tell you by what authority I do these things. When John began to baptize, was it a work of God, or was it merely something human?». They reasoned out among themselves, «If we reply that it was a work of God, he will say: ‘Why, then, did you not believe him?’. And if we say: ‘The baptism of John was merely something human’, beware of the people: since all hold John as a prophet». So they answered Jesus, «We do not know». And Jesus said to them, «Neither will I tell you by what right I do these things».
