The practical lesson of the doctrine of the Trinity is that since we are made in the image and likeness of God, the more we understand God the more we understand ourselves. Therefore, the question for us to ask today is: What does the doctrine of the Blessed Trinity tell us about the kind of God we worship and what does this say about the kind of people we should be? On this, I have two points to share with you. (1) God does not exist as a solitary individual but in a community of love and sharing. God is not a loner. This means that a Christian in search of Godliness (Matthew 5:48) must shun every tendency to isolationism. The ideal Christian spirituality is not that of flight from the world like that of certain Buddhist monastic traditions where the quest for holiness means permanent withdrawal away from contact and involvement with people and society. (2) Three is not a crowd. You remember the old saying “Two is company, three is a crowd.” The Trinity shows us that three is community, three is love at its best; three is not a crowd. Taking an example from the human condition we see that when a man (A) is in love with a woman (B) they seal the loving by producing a baby (C) Father, mother and child -- love when it is perfected becomes a trinity. We are made in God’s image and likeness. Just as God is God only in a Trinitarian relationship, so we can be fully human only in a relationship of three persons. The self needs to be in a horizontal relationship with others and a vertical relationship with God. In that way our life becomes Trinitarian like that of God. Then we discover that the so-called “I-and-I” principle of unbridled individualism which is acceptable in modern society leaves so much to be desired. The doctrine of the Blessed Trinity challenges us to adopt rather an I-and-God-and-neighbor principle. I am a Christian insofar as I live in a relationship of love with God and other people. May the grace of the Holy Trinity help us to banish all traces of self-centeredness in our lives and to live in love of God and of neighbor.
