As we conclude this remarkable sermon, we are reminded again that Jesus is not offering a message that can be separated from Himself. The Sermon on the Mount is not merely a set of moral ideals. It is not a detached “ethic of the kingdom” that we may admire from a safe distance. Rather, His whole identity is expressed in and through His words. The teaching points to the Teacher. And our response to the teaching finally reveals our response to Him.
Matthew frames this sermon in a way that helps us see the significance of what has just occurred. It begins with a formal posture of authority and ends with a formal reaction of astonishment.
“When Jesus saw the crowds, He went up on the mountain; and after He sat down, His disciples came to Him. He opened His mouth and began to teach them” (Matthew 5:1–2). This is no casual conversation. This is the deliberate scene of a Rabbi who sits and speaks with the expectation that those who hear will listen carefully. But what the crowds heard was unlike anything they had encountered.
“When Jesus had finished these words, the crowds were amazed at His teaching; for He was teaching them as one having authority, and not as their scribes” (Matthew 7:28–29). The word for “amazed” carries the force of being stunned—almost dumbfounded. They were not merely interested. They were shaken by the weight of what they had just heard.
And the reason is clear: the scribes spoke by authority, but Jesus spoke with authority. There is a vast difference between the two.
The Authority That Does Not Borrow Its Weight
The scribes often appealed to other rabbis, other traditions, other schools of interpretation. Their authority was derivative. They cited and compared and weighed opinions. But Jesus says, again and again, “You have heard that it was said… but I say to you.” He does not merely explain Scripture. He speaks as One who stands over it—not in contradiction to it, but as its rightful fulfillment and final Interpreter.
