We always say that God is not a puzzle to be solved, but the unfathomable reality within and beyond everything that is, ever has been or ever will be. Yet people do find the doctrine of the Trinity puzzling: somebody recently said to me that it seems as though the Church, at least in the West, is “a little fuzzy about it”. While we should not feel worried if we think we have not fully grasped the reality of God, at the same time we are encouraged to want to understand more deeply. This, after all, is what theology is: faith seeking understanding.
