A book entitled Stories for the Heart was published a few years ago by inspirational speaker Alice Gray. It is a compilation of what Gray calls “stories to encourage your soul;” one of them is the following story, whose original author she says is unknown. It may not be true, but I (for one) hope it is:
It was a few weeks before Christmas 1917. The beautiful snowy landscapes of Europe were blackened by war. The trenches on one side held the Germans and on the other side the trenches were filled with Americans. It was World War I. The exchange of gunshots was intense. Separating them was a very narrow strip of no-man’s land. A young German soldier attempting to cross that no-man’s land had been shot and had become entangled in the barbed wire. He cried out in anguish, then in pain he continued to whimper.
Today, as I write this, is Trinity Sunday 2020, but my imagination this morning is not caught up by the Lectionary gospel lesson of the day, the last mountain-top experience of the Eleven when, just before his Ascension, Jesus gives them the Great Commission. Rather, my mind is taken to another mountain-top story, the one New Testament story Episcopalians can count on hearing twice each year at celebrations of the Holy Eucharist, that of the Transfiguration of Jesus. It is heard on the Feast of the Transfiguration, August 6, when Luke’s version is read at the mass:
Jesus took with him Peter and John and James, and went up on the mountain to pray. And while he was praying, the appearance of his face changed, and his clothes became dazzling white. Suddenly they saw two men, Moses and Elijah, talking to him. They appeared in glory and were speaking of his departure, which he was about to accomplish at Jerusalem. Now Peter and his companions were weighed down with sleep; but since they had stayed awake, they saw his glory and the two men who stood with him. Just as they were leaving him, Peter said to Jesus, “Master, it is good for us to be here; let us make three dwellings, one for you, one for Moses, and one for Elijah” — not knowing what he said. While he was saying this, a cloud came and overshadowed them; and they were terrified as they entered the cloud. Then from the cloud came a voice that said, “This is my Son, my Chosen; listen to him!” When the voice had spoken, Jesus was found alone. And they kept silent and in those days told no one any of the things they had seen.
It is also always heard on the Last Sunday after Epiphany when, depending on the Lectionary year, it may be Luke’s story or the essentially similar versions from Matthew or Mark.
There is an old tradition in the church: on Trinity Sunday, rectors do their best to get someone else to preach. If they have a curate or associate priest, he or she gets the pulpit on that day. If not, they try to invite some old retired priest to fill in (as Father George has done today). No one really wants to preach on Trinity Sunday, the only day of the Christian year given to the celebration or commemoration of a theological doctrine, mostly because theology is dull, dry, and boring to most people and partly because this particular theology is one most of us get wrong no matter how much we try to do otherwise. Back when I was a curate getting the Trinity Sunday assignment, my rector encouraged me with the sunny observation that, listening to a sermon in almost any church on Trinity Sunday, one could be practically guaranteed to hear heresy.
As I started preparing to preach on this Trinity Sunday, however, I thought, “I have an out, a handy escape hatch” because today is not only the church’s feast of the one, holy, blessed, and glorious Trinity, it is also the secular, some say “Hallmark,” holiday of Father’s Day. So, I thought, “I’ll talk about Father’s Day and if the Trinity decides to show up, well … that’ll be fine.”
Some of you may have heard of Brooks’s law, which has to do with the time it takes to complete a software project. It’s similar to the general law of diminishing returns in economics. Professor Fred Brooks of the University of North Carolina first proposed the law in 1975; it holds that “adding manpower to a late software project makes it later.” Each additional worker must be trained and adding more workers increases the need for intercommunication between them so that, at some predictable point, the efficacy of adding more members to a task group is cancelled and doing so lengthens, rather than shortens, the schedule.
I didn’t know about Professor Brooks and his law until I started researching this sermon, and I only learned about it because in the early pages of his book he cites the Anglican theologian Dorothy Sayers and her theology of the Trinity. I will come back to Ms. Sayers and her helpful analogy for the Trinity, and later I’ll return to Brooks’s law, but first I want to share with you some of the metaphors for the Trinity, that peculiar understanding of God that we Christians hold and that we focus on each year on this, the first Sunday after the Feast of Pentecost.
