Today’s gospel, a continuation of Matthew 16 that we began last week, shows Peter falling out of grace before he had any time to settle in. Last Sunday we heard in St. Paul’s letter to the Romans 11: 33 -36, that God’s judgments are “inscrutable” and God’s ways “unsearchable.” St. Paul asks: “who has known the mind of the Lord or who has been his counselor”? In today’s gospel, Jesus rebukes Peter because he is “thinking not as God does, but as human beings do." Of course, none of us can think exactly like God, not even Peter
Last week Peter was the hero of the gospel. His confession of faith earned him a new name, Rock, the rock on which Jesus planned to build his church. This week Peter is still a rock; however, he is now a stumbling block, an “obstacle” to Jesus and his mission. Like Jeremiah in the first reading, Peter, who received Jesus’ blessing last week, now finds himself heaped with “derision and reproach.” Although Peter recognized Jesus as “the Christ, the Son of the living God,” he could not comprehend the reality of the cross. He was thinking in terms of a champion King, a triumphant Messiah, not a suffering servant. He did not understand that Jesus’ victory could only come through sacrifice, suffering, death and resurrection.
Jesus told the disciples repeatedly that there is a cost to discipleship. Just as he had to take up the cross and die in order to fulfill his mission, the disciples had to be willing to deny themselves and take up their crosses in order to follow him. They had to clear away their very human mental and physical stumbling blocks so they could carry on the mission of Jesus and build the Kingdom here. We have to do the same. Jesus reminds us that we will be held accountable, “For the Son of Man will come with his angels in his Father’s glory, and then he will repay all according to his conduct.”
Father, help us to seek the values
that will bring us lasting joy in this changing world.
In our desire for what you promise,
make us one in mind and heart.
Grant this through our Lord Jesus Christ, your Son,
Who lives and reigns with you and the Holy Spirit,
God, forever and ever.
Amen
