We would never have known that God is a family of three persons had it not been told by Jesus. He revealed his startling nature to us for the first time after his baptism. As he came out of the waters of the Jordan, the Holy Spirit descended on him in the form of a dove, the heavens opened and a voice said, “This is my beloved Son in whom I am well pleased.” (Mk 1:11) Throughout his life on earth Christ was forever talking about God as his Father and his mission was to do the will of his Father. He referred to himself as God’s only son, and we learn that the Spirit’s job was to carry on and continue in the church the work he had begun.
Today’s feast of the most Holy Trinity celebrates the mystery of three persons in the one God, all bonded together by love. In the Trinity our minds are brought into loving contact with the complexity and wonder of God, which no language is adequate to describe. His greatness and goodness exceed the boundary of all thought and are beyond our human attempts to comprehend. We should never look on the Trinity as a problem to be solved, Christ has given us this special insight into the inner nature of God to make us aware of the life we share at out baptism, when the Holy Spirit is poured into our hearts, making us adopted children of the Father.
On this feast we pray the simplest of Christian prayers:
‘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.’
