Today is Trinity Sunday and I provide a reflection on the notion of a triune God, drawing particularly on Proverbs 8, as well as Genesis 1 and Romans 5. The crux of it is that relationality is central to the being of God – the three-in-oneness of God. Therefore, the core of human life also is relationality. We need to invest in relationships, and we need to give particular attention to those relationships that are struggling or fragile.
