Trinity Sunday is a bit of an odd one out in the Church’s year as we celebrate a doctrine – a way that Christians have defined their understanding of God. The doctrine of the Trinity affirms that at the very heart of God lies difference and distinctiveness but also unity and harmony. This gives us hope for our world that the beautiful multiplicity held in harmony in our universe is no accident because the source and heart of all reality is the one we call “God” – three in one. To live in the life of the Trinity is to embrace diversity and work towards holding it in unity.
As we explore the nature of God from different facets we find we can see God “beyond”-creator, God “beside me” as friend and companion in Jesus, and God “within” as Holy Spirit. The all-embracing nature of the Trinity is what gives it its power. This collect prays that if we hold fast to this vision of God it will be a way of keeping us from “all adversities”. If we allow the threefold nature of God to permeate into our being then we are somehow caught up into its strength. The Trinity is not a closed shop, but an open invitation to us all.
