This Sunday we celebrate Trinity Sunday which is a celebration in honour of the Father Son and Holy Spirit. The three persons in the trinity reveal the fullness of the unity of God’s love. How do we understand the Trinity? We don’t! God, by definition, is beyond imagination, beyond language. The Christian belief that God is a trinity helps underscore how rich the mystery of God is and how our experience of God is always richer than our thoughts and language about God. The feast of the Trinity goes back to 12th century England and St Thomas a Becket, Archbishop of Canterbury. Historians say the great Thomas celebrated a Liturgy in honor of the Trinity in his cathedral. So was born the observance. In the 14th century, the feast came to be observed by the universal Church.
The belief in the Trinity goes back to the New Testament. There it is mentioned about forty times. We open each Liturgy especially the Mass invoking the Trinity . We also close Mass and so many other liturgies by calling upon those same 3 Persons (Father Son and Spirit) in blessing us as we go out into the world. Trinity Sunday is the day when we stand back from the extraordinary sequence of events that we’ve been celebrating for the previous five months—Advent, Christmas, Lent, Holy Week, Easter, Ascension and Pentecost it is the day when we are asked to rub the sleep from our eyes and discover what the word ‘god’ that is Father Son and Spirit might actually mean for us. This is a feast which should speak to us of this simple fact of faith: the Father loves us, has revealed that love in his Son, and has called into a relationship sustained by the Spirit. It is our joy that, as baptized members of the Church, we can somehow share in that divine life and love which is the Trinity becoming children of God.
God has chosen us, and we are his own people, just as he chose the people of Israel long ago. Each Trinity Sunday, we only scratch the surface of this great mystery of our faith. In gratitude let us begin and end every prayer with greater reverence when we say “In the name of the Father, and of the Son, and of the Holy Spirit. Amen.”
