This is a key question. Supposing it could be shown without a shadow of a doubt that the Bible told us to hate people and commit murder. Would we obey? If not, then clearly there is an inner sense of what is right that transcends the Bible and indeed, that transcends all scriptures.
Eating food is not a moral issue. How our eating affects others, who need to eat, is. Sex is not a moral issue. How we handle our relationships, is.
A key question for every Christian since the beginning of the Christian Era, is whether he or she would recognise Christ at the Second Coming. Well, the Second Coming is upon us. Christ is here, working through all those souls who see religion as an inner path or journey. The amazing growth of new spirituality, of religions beginning to recognise the validity of other religions, is the manifestation of Christ coming once again upon our shores. This is a Second Coming Christ who is not One, but who is Everyone.
