I'm troubled by the absence of Christian voices in the ethics discussions so far. Atheists and agnostics are represented, but I know I have some Christian readers, and they are thus far silent. This project cannot succeed without discussion from all parties - the presence of a Christian perspective is vital. (Ideally, I would also like a Muslim perspective, and other religious perspectives, but these seem harder to come by...)
I am hoping that this silence is simply because the Christians are too busy to comment, or have nothing yet to say, and not that they are too troubled by what is implied by relative ethics to want to air their views. I am not proposing anything that should be a challenge to one's faith - relative ethics does not remove absolutes, it merely contextualises them (and observes that only God is in a position to know the answer to all things). It asks that we respect the God-given right of free will, in the loving manner implied by Jesus' teachings. If you have questions on how to relate anything said to your Christianity, I am happy to discuss it with you - the purpose of the exercise, after all, is communication.
I hope that I am just being paranoid; if you can assuage my concerns, I would be grateful for your comment.
