It is the tradition of the Church to celebrate Trinity Sunday one week after Pentecost. In this way we honor one of he most fundamental Christian beliefs that God is three and yet one. While we will never fully comprehend this great mystery of our faith, we can make some attempt to plum the depths of this beautiful truth of faith. The following formula will help us : God is three Persons in one Nature. The three Persons of God—Father, Son, and Holy Spirit—are all equally God, and they cannot be divided.
Having a God who is a community is especially significant when we remember that we are made in the image of this God. In other words, we are made to be in communion. It’s interesting to note that a Catholic anthropology of the person suggests that the smallest unit of society is not the individual, but the family. Our identity as human persons comes from our relationships. A person born alone on a desert island would not know what it is to be a human person.
The inner life of the Trinity is marked by total gift, and total reception of love. It’s no accident that this too should lead us to live a life premised on both self-gift and complete receptivity to the will of God.
Let’s pray this weekend that we might have the grace to imitate more and more the inner life of the Trinity.
