“The most important decision in Christian theology is to decide whether you will speak of God as a person or as a concept, as a name or as an idea. Talk about God as, to use Paul Tillich’s term, “ultimate reality,” and you will get a safe, dead abstraction that you can utilize in whatever salvation project you happen now to be working. Name God as Father, Son, and Holy Spirit, and God will enlist you in God’s move upon the world.”
