Sermon for Trinity Sunday
“Behold a door was opened in heaven”
Today is Trinity Sunday. It celebrates the great, grand, and central teaching of the Christian faith. It is about the extravagance of God, how God is always more and greater than we can ever imagine. The Trinity is that greater extravagance – the extravagance of God, both in himself and for us. The Trinity is the mystery of God revealed, the mystery of love made known, the love that is God.
Think God and everything else comes after. But how can we think God? Only by the extravagance of God’s grace that embraces and enfolds us in the community of love, the communion of God. There is the extravagant grace of Holy Baptism when we are named in the intimacy of God’s own naming of himself as the Father, the Son, and the Holy Spirit. There is the extravagant grace of Holy Communion which gathers us into the community of love, the communion of the Trinity.
And there is the extravagant grace of language, the language of Creed and Liturgy, of poetry and song. It is the language of adoration. The language of adoration is grace-given and spirit-inspired. The Athanasian Creed, found tucked away in the back of the Prayer Book, for example, proclaims in the most extravagant language imaginable the mystery of the Trinity by way of negation and affirmation.
God is always more – always of another order of reality beyond the mundane and the worldly, beyond what is merely human. “He therefore that would be saved, let him thus think of the Trinity” – think of the Trinity in this way, the way which God in the extravagant grace of his Son has opened out to us.
