On gay marriage...
If we agree: Government has no "business" (i.e. sanctioned authority or assigned obligation) in ths matter, why should "the church"? If two Agnostics or Aethiests (gay or straight) wish to marry, what "authority" sanctions their union? The Church's involvement is traditional, not imperative - except to the Believer. A basic motivation behind gay marriage is to satisfy legal requirements to gain access to actions and/or benefits otherwise denied to a non-relative. Changing or eliminating those unnecessary hurdles would be far easier, less threatening to the culture and thus make a lot more sense than once again calling on Governemnt to resolve a problem it crerated while having no authorizatioon to be involved in the first place.
