As a choirboy in the 1960s, I used to amuse myself during what felt like interminable sermons by flicking through the pages of the Book of Common Prayer. I quickly formed the view that, after the exciting events of Christmas, Epiphany, Easter and Whitsun the author’s imagination had run out when it came to the Trinity season. So we had a succession of Sundays ‘after Trinity’ from the first, the second, the third…right up to the twenty-fifth until things restart in Advent. All very dull and boring.
These days, I see it differently. The celebration of Trinity Sunday draws together the divine activity in creation and redemption made known through the threefold action of God – Father, Son and Holy Spirit. Human beings are incorporated into this life through faith and baptism in the name of the Trinity. Our lives are to be patterned individually and corporately upon a God who makes himself known as a diverse unity. And so all human life is lived as a series of events ‘after Trinity’ until the last great day when God in his Advent makes all things new.
