In
San Francisco (of course), people founded
St. John's African Orthodox Church based on his work. St. John refers not to Jesus' disciple but to Trane himself. The song, and Coltrane, are the basis for their worship, the foundation of their faith.
I'm going to San Fran in October, and I'll be at the church on Sunday. Even if Coltrane's not God, he can't be that far off.
