He spoke a bit about the background of the feast day. Saint Peter was the Rock on which Christ chose to build His Church. Saint Paul was the missionary who brought the Christ to the Gentiles. Sometimes they fought with each other, but in the end they reconciled, agreeing that Christ's message of Love was a message for all, not just a chosen few. In the end, they both became martyrs for the faith who fought with one another but reconciled.
He discussed the importance of not being overly judgmental. Jesus confronted the Pharisees, who tried to make the Laws of God the laws of man. Some try to make the laws of man the Laws of God.
And he talked about the importance of love, especially love (not narcissism) of one's self. If you are not happy with yourself, you need to identify why. Once identified, you need to apply God's Law of Love to the problem.
I wish I had something to write with as I was listening to him because I have already forgotten several of his main ideas; I certainly haven't given enough credit for the points I did remember.
