Continuing with his illuminating series, in part four Fr. Stephen Freeman discusses those (both non-Orthodox and Orthodox) for whom knowledge of God is but a relationship with a book (albeit a sacred book) or with ideas about God. These people are what Fr. Freeman calls "practical atheists." "Although a person may espouse a belief in God, it's quite possible for that belief to be so removed from everyday life that God's non-existence would make little difference."
