The Sunday after Pentecost, this coming Sunday, is known as Trinity Sunday. I used to make fun of Trinity Sunday. Exactly what event are we celebrating? “Oh yes, that's the day we read our favorite Trinity story!” We all know that on Pentecost, you read Acts 2. On Christmas, Luke 2. For Trinity Sunday, what? The three mysterious visitors to Abraham and Sarah at the oaks of Mamre, (Genesis 18), perhaps?
Back then I viewed the Trinity more as divine minutiae, an arcane embarrassment, the byproduct of underworked and overly-imaginative theologians, a topic one could not discuss for more than thirty seconds without falling into some heresy. If I slip into heresy here, please let me know.
Now, the Trinity has become for me a mystery to be celebrated, a delightful eccentricity that refuses to be digested by our schemas. Trinity is the very heart of God, and in turn, informs us greatly about what it is to be human.
As my appreciation for the Trinity has increased, I’ve also come to welcome Trinity Sunday. In fact, the trio of Ascension, Pentecost, and Trinity Sunday has become a fun, faint echo of Easter and the Holy Week events. Of course, this relishing of the Trinity is not some solo journey, my great personal revelation. Trinity has been a hot topic in theology for a couple of decades, richly mined by all sorts of good folk.
