A sermon preached by the Rev’d Dr Daniel Dries Trinity Sunday Christ Church St Laurence – 22 May, 2016 May the words of my mouth and the meditations of our hearts be acceptable in your sight: O Lord, our strength and our Redeemer. Amen. It is said that St Augustine was struggling to come to terms with the great mystery of the Trinity. As he walked along the seashore, he stumbled across a small boy who was scooping water into a seashell and pouring it into a hole in the sand. St Augustine asked the boy what he was doing. The child responded, ‘I’m going to take all the water out of the sea and pour it into this hole.’ As the great saint smiled in response to the child’s unrealistic task, he realised that he was himself being just as foolish—imagining that he could get the whole nature of God into his limited human mind. This possibly apocryphal story of St Augustine is a typically gentle reflection on the unknowable mystery that we celebrate and affirm today. In contrast, with just a hint of evangelical bluntness, John Wesley affirmed the mystery of it all as he said, ‘Bring me a worm that can comprehend a man, and I’ll show you a man that can comprehend the Triune God.’ Great theologians like Augustine and John Wesley affirmed that the Trinity is destined to remain a mystery. We could then ask why we would even bother to waste time wrestling with it. We could just continue on with the Creed and get to morning tea 10 minutes earlier. The only problem is that the Creed and almost every aspect of our faith is based on the Trinity. We are baptised in the name of the Father, the Son and the Holy Spirit; the departed are sent on their way and blessed in the name of the Trinity. Although we will never fully come to terms with it, Christians are compelled to grapple with this doctrine primarily because it was first taught by Christ himself. Scripture, as early as Genesis, prepares the way for the doctrine of the Trinity, although The Gospel according to John gives us the basis of Trinitarian Theology. Having constantly prayed and referred to the Father, in John, Chapter 16, Christ now foretells the coming of the Spirit. As the great Farewell Discourse moves towards its conclusion, Christ promises the disciples the sending of the Spirit that will continue to guide them in truth. Christ’s language moves seamlessly from himself to the Father and to the Spirit, and yet he makes this great disclaimer: ‘I still have many things to say to you, but you cannot bear them now.’ Augustine talked about pouring the ocean into sand; Wesley spoke of intellectual worms—the message is the same: try to believe, even though you won’t fully understand. Although Christ himself assures the disciples that they would not completely grasp his teaching, we continue to try. Sometimes we try too hard. Preachers deliver black and white sermons desperately attempting to convince the faithful that this is all perfectly logical. In terms of the Trinity, various metaphors have been used to suggest that this doctrine is not nearly as complicated as it appears. St Patrick famously used the shamrock, presumably because it Page | 1
