Today the Church celebrates Trinity Sunday. It is a day to bask in the wonder of knowing the triune God—Father, Son, and Holy Spirit—who has been revealed to us in the Scriptures. While we often think about the three persons of the Trinity having their own areas of expertise (the Father creates, the Son redeems, the Spirit sanctifies), the readings for today focus on how the three persons of the Trinity work together in every task. In the Old Testament Reading from Genesis, we see all three persons are present and active in the creation of the world. In our reading from Acts, we see all three persons active in the salvation of the world. And in the Holy Gospel from Matthew, we see that all three persons are active in the new life we have as baptized children of God.
