Authority of Jesus questioned
According to the Gospel of Matthew:
Jesus entered the temple courts, and, while he was teaching, the chief priests and the elders of the people came to him. "By what authority are you doing these things?" they asked. "And who gave you this authority?" Jesus replied, "I will also ask you one question. If you answer me, I will tell you by what authority I am doing these things. John's baptism—where did it come from? Was it from heaven, or from men?"
