Let me tell you a story. In our congregation we have an auction every other year and one of the things auctioned off is a chance to request a sermon topic. One year the member who won that auction item requested that I talk about nuclear weapons. Well, sure, I said… and then I put the suggestion in my sermon topic folder. Each month as I chose sermon topics for the next month, I would see it there, but I wasn’t sure yet what I would do with it. What could I say about nuclear weapons?
I was reminded of the old story about President Calvin Coolidge. One Sunday, with his wife sick, he went to church alone. Upon his return she asked, “What did the pastor talk about?” Coolidge said, “Sin.” “And what did the minister say about sin?” “He was against it.” Well that’s about what I had for nuclear weapons: I was against them.
For me, a worship service is meant to be about hope. And nuclear weapons are one of the most terrifying dangers that we face in our world. The mushroom cloud image of the atomic bomb represents the potential destruction of most life on earth. So I have to admit, I didn’t feel like researching how bad things were, what new weapons were being created, or who might try to use them. And most of all, I wasn’t sure what I could say next. I never want to send people home from worship with more fear or despair than they came in with. So the topic sat in my folder, and I occasionally added an article or resource to the file; but each month, I’d say, I’ll do that one later.
How do we face the biggest dangers that threaten our world? What gives us courage and hope? Several months later, I came upon an article about mushrooms. It was an interview with Paul Stamets, about How Mushrooms Can Help Save the World.
I have to admit that I had never been a big fan of mushrooms. I tolerated their presence on pizza and in casserole dishes. I had never experimented with the psychedelic varieties back in college. A while ago, Margy started taking photos of mushrooms, as they popped up in our back yard, and that helped me to appreciate their strange and diverse beauty. But I had no idea.
I had no idea that mushrooms were the fruit of the mycelium, a vast underground network of fungal fibers that can stretch for miles. I had no idea that those fibers form one entity called a mycelial mat. I had no idea that a mycelial mat in eastern Oregon was considered by scientists to be the largest organism in the world. It covers twenty-two hundred acres and is more than two thousand years old.
I had no idea that mycelial networks regulate the nutrients of plant life in the forest, transferring sugars from tree species that have enough to other tree species that need more to survive. And most of all, I had no idea that mycelial networks communicate. To do this they use methods similar to those found in the nerve fibers in our own brains; they use some of the very same neurotransmitters that allow us to think.
