Trinity Sunday challenges us to understand not just what God does, but who God is at the very core. The Trinity reveals that one God exists as Father, Son, and Holy Spirit - three distinct persons sharing one divine essence. Rather than focusing on different roles, the Trinity shows us that God's fundamental nature is self-giving love. This love overflows into creation and transforms how we view our daily activities. When we understand that God is love loving and being loved, our ordinary tasks become opportunities to reflect God's life-giving nature and participate in loving the world around us.
