This week we return to the liturgical season of Ordinary Time. This Sunday and next Sunday, however, are designated as solemnities, special days that call our attention to the central mysteries of our faith. Today, on the first Sunday after Pentecost, we celebrate the Solemnity of the Most Holy Trinity. This feast invites us to consider what we believe about God, who has revealed himself to us in the Trinity, one God in three Persons. The Gospel for this Solemnity is taken from the Gospel of Matthew. In its conclusion, Matthew’s Gospel quickly moves from the disciples’ discovery of Jesus’ empty tomb and Jesus’ appearance to Mary Magdalene and the other Mary to the commission that Jesus gives to his disciples in today’s Gospel.
Jesus commissions his disciples to baptize in the name of the Trinity; this is one of the clearest attestations for Baptism in the name of the Holy Trinity found in Scripture. Other New Testament references to Baptism describe it as being celebrated in the name of Jesus. As we read this Gospel on the Solemnity of the Most Holy Trinity, we are reminded that this central mystery of faith is meant to be lived. As baptized Christians, we share in the life of the blessed Trinity and seek to invite others to share in God’s love.
