Holy Trinity Sunday. Though the word trinity is not found in the scriptures, today’s second reading includes the apostolic greeting that begins the liturgy: The grace of our Lord Jesus Christ, the love of God, and the communion of the Holy Spirit be with you all. In the gospel Jesus sends his disciples forth to baptize in the name of the Father, and the Son, and the Holy Spirit. More than a doctrine, the Trinity expresses the heart of our faith: we have experienced the God of creation made known in Jesus Christ and with us always through the Holy Spirit. We celebrate the mystery of the Holy Trinity in word and sacrament, as we profess the creed, and as we are sent into the world to bear witness to our faith.
