If I were in Warren’s place, representing a large congregation, I would have been inclined to reach out to zero as well. Rick Warren has never indicated regret for his action, however, the way things turned out, he may. 20 / 20 hindsight is fairly easy. His approach could have used some polish and I wish he had stood on principal more than he did. I believe his heart was in the right place but he should have checked with some Christian Brothers before stepping out.
Nobody ever thought any less of Billy Graham because he had the guts to man up, admit he had no business promoting politicians and then kept his promise from then on.
