Though I'm posting this question in several threads scattered through CF, I'm not trolling or seeking to be contentious. I'm genuinely curious to find out how this question might be similarly or differently addressed by various groups within Christendom. And, please, though I know that whole books could be written in response, try to distill your own answer down to a single sentence, such as might be used when designing a poll.
