Matthew 16:13-20.
Those who sounded hosanna, some days later days later were seen yelling crucify him as Jesus was declared heretic by the Pharisees and the Scribes.
When the identity of Jesus was questioned, he asked his disciples who do people say the son of man is? They gave him all sorts of names and he said what about you? Peter replied you are the Messiah, the son of the living God. Jesus said flesh and blood never revealed this to you but my Father in heaven. Jesus blessed Peter and said, on you Peter, the rock, will I build my temple and the gates of hades will not prevail against it.
To me Jesus is the son of the living God and the supreme saviour of the falling creation. Our knowledge of who he is result in our blessings. Amen.
