Today’s reading for the Feast of the Holy Trinity comes from the very end of Matthew’s Gospel. After rising from the dead, Jesus meets the apostles on the mountain top. There are only eleven left – Judas has gone. When the disciples see the risen Jesus, they fall down and worship him, but some hesitate. They ran away and abandoned Jesus when he was arrested. They saw him die. Now that he has risen from the dead, the disciples’ joy is mixed with uncertainty and confusion.
Jesus sends his followers out with a mission. He wants them to pass on the Good News that they have heard from him, and to make disciples of people from all the nations. Jesus chooses the apostles for this mission, knowing that they are weak and sinful men, who let him down at his worst moment.
The disciples did spread the Gospel all over the world. We are among the people of all nations, who have been baptised in the name of the Father and of the Son and of the Holy Spirit. Like the disciples, Jesus has chosen us, although we are sinners, for the mission of spreading the Good News. God has revealed to us the mystery that Father, Son and Spirit are one God in three Persons. We can never fully understand the Holy Trinity, but today we celebrate the mystery.
