The baptism of John, from where was it? from heaven, or of men?
And they reasoned among themselves, saying, If we shall say, From heaven; he will say unto us, Why did you not then believe him?
Read Chapter 21
John Chrysostom
AD 407
And what sort of inference is this? The greatest surely. For if they had said, from heaven, He would have said unto them, why then did ye not believe him? For if they had believed, they would not have asked these things. For of Him John had said, I am not worthy to loose the latchet of His shoe; and, Behold the Lamb of God, which takes away the sins of the world; and, This is the Son of God; and, He that comes from above is above all; John 4:31 and, His fan is in His hand, and He will thoroughly purge His floor. Matthew 3:12 So that if they had believed him, there was nothing to hinder them from knowing by what authority Christ does these things.
