Come Holy Spirit, Comforter, Spirit of Truth,
everywhere present and filling all things.
Treasury of Blessing, Giver of Life,
Come, dwell within us and between us… Amen.
On the day of Pentecost, the disciples, “filled with the Holy Spirit” rushed out into the streets of Jerusalem “and began to speak in other languages, as the Spirit gave them ability,” proclaiming the Good News to the crowds of people in town for Shavuot and answering their inevitable questions. Jesus had told them, “Do not let your hearts be troubled, and do not let them be afraid.” The Spirit, as Jesus promised, had reminded them and empowered them, and now here they were.
Scholars and preachers go through all sorts of hermeneutical contortions to interpret this event as some sort of reversal or overcoming of the linguistic scattering of the nations at the Tower of Babel. I suppose that’s why our lectionary pairs that Genesis story with the reading from the Book of Acts, but I don’t think that’s what Luke, the author of Acts, was trying to convey. I’m always left wondering, “If that’s what he was trying to put across, why didn’t he just say that?”
At the end of our gospel lesson this morning, Jesus said to the crowd, “It is my Father who gives you the true bread from heaven. For the bread of God is that which comes down from heaven and gives life to the world.” They said to him, “Sir, give us this bread always.” Jesus answered, “I am the bread of life. Whoever comes to me will never be hungry, and whoever believes in me will never be thirsty.” This is the beginning of Jesus’ long discourse on bread which takes up nearly the whole of Chapter 6 of the Gospel according to John and of which we will hear parts for all of the month of August.
A few verses further on, Jesus will say again, “I am the living bread that came down from heaven.” And he will add, “Whoever eats of this bread will live for ever; and the bread that I will give for the life of the world is my flesh. . . . Those who eat my flesh and drink my blood have eternal life, and I will raise them up on the last day; for my flesh is true food and my blood is true drink. Those who eat my flesh and drink my blood abide in me, and I in them.”
The Jews, John tells us, disputed among themselves as Jesus was delivering this lengthy dissertation on bread. I think we can understand why! The very idea of consuming human flesh is off-putting, even disgusting, and would have been extremely objectionable to the Jews; no wonder they grumbled and mumbled, complained and disputed. Even as a metaphor, the statement demands a lot from Jesus’ followers!
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.
