If you ever want to stump someone with a trivia question about the Episcopal Church, ask them “What is our only major feast that celebrates a teaching?” The answer is this one: Trinity Sunday. It’s a terrific day because we get to focus on who God is – a question so important, and so determinative of how you live your life, that we don’t want to get it wrong.
Sometimes church folks talk about the Trinity with a kind of embarrassment, as if the concept were an obscure, non-essential matter along the lines of arguing over how many angels can dance on the head of a pin or whether to use violet or blue hangings in Advent. Even some clergy joke about how arcane the Trinity is, and how they wish they didn’t have to preach today – which is something I really don’t get. You’re clergy, and you don’t want to talk about who God is? What do you want to talk about? God isn’t exactly an optional extra.
