Seventeenth Sunday after Pentecost - Rev. Russell Johnson

And when he entered the temple, the chief priests and the elders of the people came up to him as he was teaching, and said, "By what authority are you doing these things, and who gave you this authority?"  Jesus answered them, "I also will ask you one question, and if you tell me the answer, then I also will tell you by what authority I do these things.  The baptism of John, from where did it come?  From heaven or from man?"

Matthew 21:23-25
