When Jesus finished these words, the crowds were astonished at his teaching, for he taught them as one having authority, and not as their scribes. [Matthew 7:28-29 (NABRE)]
When Jesus finished the Sermon on the Mount, the crowds were astounded at his teaching because, unlike the scribes and Pharisees, He taught with “authority.” When the people wondered at Jesus’ authority, they weren’t referring to His ability to speak confidently and persuasively. The Greek word translated as “authority” was exousia which meant power or right; the people wondered at Jesus’ authorization to say the things He said. Rather than teach on their own authority, most rabbis taught on the authority of earlier sages. The Moody Bible Commentary depicts them as virtual “walking footnotes” who merely cited famous teachers and repeated what had been said before by others.
While it’s usually translated as “Verily” or “Truly, I say to you,” Jesus often began His teaching with the words, “Amen, I say to you.” Meaning “truly” or “certainly,” the word “amen” was used at the end of a prayer to confirm its words. It also was said when affirming a pledge; saying “amen” at the end of an oath made the vow valid and binding. By saying, “amen” before He spoke, Jesus was guaranteeing the truth of His words: His distinctive power and right. In effect, Jesus was announcing, “I say this to you indisputably, unequivocally, and with the fullest authority.”
A perfect example of Jesus’ claim of authority is found in His lesson about building on a solid foundation (written about yesterday). His simile echoed one used by many Jewish rabbis but with one very important difference. In the rabbis’ version, the solid foundation was to be the Torah; in Jesus’ version, the unshakable foundation was His word! His audience must have been shocked by those words; it’s no wonder they marveled at the authority He claimed.
When we look at the authority with which Jesus taught and acted, we can see why the priests, teachers and elders felt their position threatened. When they demanded to know by whose authority Jesus acted and spoke, they weren’t interested in an answer; they just wanted to trick Him into saying something that would label Him as an eccentric fanatic or a blasphemer. Like a true rabbi, Jesus answered their question with one of His own and asked where John the Baptist got his authority. Instead of backing Jesus into a corner, He’d backed them into one. If they said John had no authority, the people would be angry and, if they said John’s authority was from God, they’d have to answer for not believing and supporting the Baptizer. When they refused to answer, so did Jesus.
It had been a long dry spell for the people of Palestine; before John, the last time God spoke was through the prophet Malachi more than 400 years earlier. When Jesus spoke, the people were again hearing the Word of God! The difference was that John and the other prophets knew they were mere messengers; the words they spoke were not their own. When Jesus spoke, he wasn’t God’s messenger; He was God’s Son. Jesus didn’t just have authority; He was the incarnate Authority of God!
