The following text guided the homily:
* Often when I ask people — students at Columbia and other Catholics in various adult education sitautions — what is the most important teaching in Christianity, I get various answers. Some will reply with Christological dogmas like the Incarnation or the Resurrection. More often people will respond with moral teachings, like “You shall love the Lord your God with all your mind, heart, soul and strength,” “Love one another as I have loved you,” “Whatever you did to the least of my brothers, you did to me” or “do unto others what you would have them do to you.” But the top of the hierarchy of Christian teachings is, by far, the revelation of God as the Blessed Trinity.
* The Catechism of the Catholic Church, in an extraordinarily important paragraph (CCC 234), emphasizes, “The mystery of the Most Holy Trinity is the central mystery of Christian faith and life.” It is what most distinguishes Christianity from every other religion. Ancient Greek and Roman pagans were polytheists, believing in many opposed gods. Buddhists are agnostic. Hindus are pantheistic. Jews and Muslims are monopersonal monotheists. We Christians, on the other hand, are Trinitarian monotheists, which is why the mystery of the Most Holy Trinity isthe central mystery of the Christian religion.
* Because lex orandi, lex credendi, lex vivendi, because the way we pray impacts how we believe and how we live, it is very important that we pray our faith in the Trinity. This became clearer to the Church over time. While every Sunday is, in a very real sense, dedicated to God and therefore every Sunday really is Trinity Sunday, since the 1300s, the Church has celebrated on the Sunday immediately following Pentecost a feast dedicated to the Holy Trinity, to help all of us focus more explicitly on God is in his profound mysterious depths, and therefore on who we’re called to be made in His image and likeness.
* The Trinity is first, the central mystery, note, with regard to what we believe. The Catechism tells us why: “It is the mystery of God in himself. It is therefore the source of all the other mysteries of faith, the light that enlightens them. It is the most fundamental and essential teaching in the ‘hierarchy of the truths of faith.’” The mystery of the Trinity, therefore, enlightens the mystery of Creation, the mystery of Redemption, the Mystery of Sanctification. It illumines every page of Sacred Scripture. It sheds light on the four last things. It reveals what is at the root of all of the sacraments and prayer. The Catechism states, “The whole history of salvation is identical with the history of the way and the means by which the one true God, Father, Son and Holy Spirit, reveals himself to men ‘and reconciles and unites with himself those who turn away from sin.” Underneath the history of the world, underneath our own personal history from the moment of our conception in our mother’s womb, until now and beyond, has developed within this mystery of the Blessed Trinity. Therefore, it’s crucial for us as human beings, not to mention believers, to pour ourselves into the mystery of the Trinity.
* This leads to the second point the Catechism underlines: the Trinity is likewise the central mystery with regard to Christian life. The Christian life is meant to be a Trinitarian life. Your life, my life, is meant to be a Trinitarian life. And so the most important moral question we need to ask, answer, and live is how do we live a Trinitarian life?
