And when Jesus finished these sayings, the crowds were astonished at his teaching, for he taught them as one who had authority, and not as their scribes.

=================================
"You will say, 'Christ saith this, and the apostles say this;' but what canst thou say? Art thou a child of the Light, and hast thou walked in the Light, and what thou speakest, is it inwardly from God?" 

George Fox saith this, and I do believe it points quite well to what Jesus' "authority" was, and where it comes from.

Many people want a clear and unambiguous source of what they call "Authority", meaning ~'Something to tell people [even themselves, perhaps] how they should think, feel, and behave in all conceivable circumstances.'

Jesus did lay down guidelines as to how people needed to become & behave, so as to join with, and continue participating in our Father's way of ordering the world. 'Not judging' each other, not condemning, was among those guidelines. 

And yet people keep right on asking, "How are we supposed to judge each other; whom are we permitted [and obligated] to condemn?"
