Daniel Mayes is a Disciples of Christ pastor. He did his D.Min. at the University of Dubuque Theological Seminary, where Timothy Slemmons—creator of the Year D project, which I wrote about for the Century—was one of his advisors. Mayes’s church, First Christian Church of Spencer, Iowa, has been using Year D in worship throughout the current liturgical year. I asked him a few questions about how it’s gone.
