A recent post about this topic has illustrated clearly the need for good, solid guidelines. It has shown that we cannot reasonably expect to field all questions about Christianity. The correct response to this was that we don't try to field all questions about Christianity, rather we try to field questions about Christian Doctrine.
This was the effort of our recently implemented standards for questions and answers. What those standards boil down to is this: Questions must be about, or in regards to, in within the framework of Christian doctrine.
If a question is about doctrine, but doesn't specify a doctrine, it's Not Constructive because it turns into a voting war. If a question is about biblical interpretation but it doesn't specify a doctrine, it's actually a question about doctrine masquerading as a "Bible" question. Therefore, it has to be within a doctrinal framework or else it turns into a voting contest.
There was a special class of questions ("fact-based") that are allowed dealing with historical Christianity (ie historical doctrine), or factual questions about the Bible in general (source criticism, authorship, etc.). However these have proven to be a very minor percentage of our site and I doubt that this percentage will grow.
We now have these standards in place--standards that garnered strong initial support and have proven themselves unavoidable in order to remain a valid fact-based SE site. These standards are essentially re-forming our site to be a site about Christian Doctrine, rather than a broad, open-ended site about Christianity in general.
Should we rename our site to Christian Doctrine?
Keep in mind, I'm not referring to changing the name of the url. Christianity.stackexchange.com is, I believe, a great name. However, rebranding our site as Christian Doctrine would make every page of our site ring with the standards that we have in place.
Ultimately, the only change I'm proposing is in all the graphics that are sprinkled through our site and the SE Network.
