I was perusing an interesting exchange over on Pontifications regarding the Windsor Report - the recently released document from the Anglican Church regarding the ordination of gays and related issues (I'm honestly not familiar with its contents). Pontificator blasts the report for being an "equivocation" and not calling the American & Canadian churches to repentance for their actions which have jeapordized the worldwide communion of Anglican churches.
The very first comment comes from a gay Christian, who takes issue with Pontificator's comments about the need for repentance, citing the belief that the ordination of Gene Robinson was correct and therefore not something to be repented of. Multiple responses ensue, conversation goes off course and the gay Chrisitian (who goes by the handle 1,000 times) says that a lesbian was murdered, for her sexual orientation, in Sierra Leone and this murder was not condemned by the local Anglican bishop or any other members of the church. The argument, of course, being that the moral failure of the church in other areas prevents it from speaking authoritatively morally in other areas and that it has discriminated against gays in the past. Another poster pointed out the loophole in 1,000's logic, asking if the murderers, who clearly thought their actions were correct, needed to repent since they had done nothing wrong in their perception. 1,000 accused other posters of being incapable of making the necessary distinction, stating "loving gay relationships" cause no harm, whereas murder obviously does so. I responded, at this point, that there is no need to demonstrate that gay relationships cause no harm, since the point is not whether or not they are harmful, but whether or not they violate biblical norms - whether or not they are, in fact, sinful. 1,000's response was that this made God's law "simply irrational."
My question is, of course, does there have to be rational reason for calling a behavior or action sinful? Do we have to be able to identify specific examples or consequences of harm - to ourselves or to others - for something to be a sin? I'll let others take a shot before I offer my opinion.
