The festival of Trinity offers us the opportunity to contemplate the nature of God and marvel at it – though, of course, we will never fully grasp it, because God is not made in our likeness, but we in His. We cannot quantify and contain God’s reality. It’s a bit like looking at a rainbow. Our eyes can only perceive certain colours, while others are beyond our power of vision. The trinity suggests numbers, but as soon as we try to nail down God mathematically, we are bound to run into trouble, and the whole trinity concept reminds us that all our models and shapes are only rough guides to help us. The reality is always more, and different.
