In our first reading, Moses stood before God to turn away his wrath from his people. Jesus, of course, perfects that by paying the price for our sins. Where Moses stops God’s anger for a time, Jesus’ sacrifice reconciles God and humanity forever. Jesus is telling the Jews, particularly the religious leaders of the time, that they had missed the real message of Moses; if they hadn’t, they would have accepted him. Jesus rebukes them for not accepting praise from God alone, which is really rebuking them for idolatry. It’s a caution we can accept also today, a caution to focus on God’s action in our lives and accept his grace for what we need.
