When we were baptised, we were immersed into the life of God, who is Father, Son and Holy Spirit. And in every celebration of the Mass, that life is renewed within us. Through the Holy Spirit given us by Our Lord and Saviour Jesus Christ we offer worship to our heavenly Father.
As we turn through the pages of the four gospels we discover that they reveal to us intimate secrets about the inner life of Almighty God. From what Our Lord said and did while he was on this earth, we can grasp bits and pieces of the mystery of God. For instance, we would never have known that God is three persons: Father, Son and Holy Spirit, if Our Lord had not revealed that mystery to us.
Today’s Solemnity of the Most Holy and Undivided Trinity celebrates the mystery of three persons in the one God, all bonded together by love. This knowledge should fill us with awe and reverence, for we don’t worship a God whose limits we can define. We can’t put God in a box and say we know everything about him. In the Holy Trinity our limited human minds are brought into contact with the complexity and wonder of God that no human language can adequately describe. And it doesn’t matter that we cannot define God, for Saint Augustine tells us that when we speak about God it’s just as well that we don’t understand, for if we did understand God then he would no longer be God. A God without mystery would have no claim to our reverence. And yet we should never look upon God as a mystery to be solved, or a puzzle to be worked out, or something simply to test our faith. Our Lord has given us a special insight into the inner nature of God in order to make us aware of the life in which we share when we are baptized; when the Holy Spirit is poured into our hearts making us adopted children of the Father. Every time we make the sign of the Cross we express our faith in calling upon the name of the Holy Trinity. The sign of the Cross reminds us that it is only through the Cross of Christ that the life of the Holy Trinity is open to us, and that the Cross is the only means by which we can follow Our Lord into eternal life.
Today’s feast brings home to us just how intimate and how personal God’s love is for us. It shows God taking an interest in every individual as Father, redeemer and spiritual guide. After all our attempts to express wonder at the immensity of the mystery of God, who is just yet merciful, far yet near, completely other and different from us yet loving and caring, we rightfully acknowledge that words are a poor substitute for worship and contemplation. And so, on this day we pray the simplest of Christian prayers we all learned as children: Glory be to the Father and to the Son and to the Holy Spirit, as it was in the beginning is now and ever shall be, world without end. Amen.
