I was listening to Krista Tippett’s interview with Martin Marty[1] the other day. In it, Marty referenced the Niebuhr brothers, Reinhold and H. Richard. They were prophetic voices in the culture, he said. They weren’t much good at the more affective parts of religion like leading worship, he thought, though they did write some prayers; it was their prophetic voice, speaking with power and eloquence for justice and truth, that made them important theologians.
