Yes, and when someone chooses to actually engage in a reasoned defense of the ethical argument they are trying to make they should be called on to defend them. When we are given a book like the Bible where people can not agree, even amongst believers, what exactly it is trying to say as a moral guide, I think we'll find it falls short as a defense for a moral argument. Pointing to the Bible and merely expecting it to stand as a moral guide in and of itself is clearly not a reasoned argument. If someone wants to reason why something is morally right or wrong, they should be able to defend that position in a way that is not an appeal to authority, which is what the Biblical argument is. Neither is a bulk of literature on a subject any testament to the worth of that subject.
None of this is justification for thinking the Bible is somehow a worthwhile source of any special insight into humanity. Nor does it in anyway justify the Bible's use in justifying political decisions, as it so often is. Do you think your personal interest in the Bible somehow justifies the Catholic Church's endorsement of life imprisonment for homosexuals in Uganda?
I disagree, we even find this behavior amongst bonobo chimpanzees. We just like to think we're special and different.
This isn't even an attempt to address what I said. You just restated that my morals must be of a Christian source, it's outright begging the question. Neither is Christianity's influence even a testament to it's worth in itself for anything.
Because it allows room for debate and rapprochement. Moreover, I would go beyond that to say a moral code that respects individual autonomy is far superior to anything found in the Bible.
So? For the purposes of its worth as a moral guide, I don't care if the Bible is well written.
