The feast of the Most Holy Trinity brings us face to face with the foundation of our faith. The readings for this feast provide answers to the question: Who is God? They can really only suggest something about the mystery of God, and they can do this only indirectly. They call to mind some of the wonders that God has accomplished for us and in us. It is through reflection on these gracious divine acts that we can get glimpses of God. Jesus teaches that God sent him into the world to save it, has made us adopted children through the Holy Spirit, and will ultimately clothe us in divine glory. It is from his teaching that we hear that the Son was sent by the Father, the Spirit, which was also his Spirit, proceeded from the Father and from him.
