"Church" is a work of eidetic poetry by the mathematician and polyartist Kaz Maslanka (he has a blog called Mathematical Poetry).
"Church" was inspired by my "math-poem":
Change + purse = church.
Here's a math-poem by Kaz Maslanka. "The Proliferation of Vis-po." (It is based on a conversation we had on how the talent on display in vis-po is in reverse proportion to its proliferation. Kaz attributes the formula to me, but the art is his.)
