How many Christians are there? Around 2 billion? Then there are about 2 billion different moral codes within Christianity. Which one would you like?
False. Though there are divisions between Christians, most parishioners within any given church will adhere to the moral code expounded from the podium. So, at most, you have as many different moral codes as there are denominations and independent churches.
Would you like one that hates gays or is fine with them? One that supports abortion, or one that bans it, or one that has specific criteria (you'll have to tell me the criteria if you pick that option? Would you like Biblical literalists or those that take it more metaphorically? Creationist or Evolutionist? Which denomination? OT = relevant or OT = irrelevant or OT = sort of relevant? How important is Mary supposed to be in this morality? Are we looking at a 7 day creation? What's the most important rule(s) in the Bible for this morality? How much prayer/bible reading/church involvement are you looking for? Are you after one that supports female priests or not? What gender roles are you after? Which Bible are we looking at?
That's a very small percentage of the questions we have to look at.
1.) I sincerely doubt that the majority of Christians identify with Westboro Baptist.
2.) Taking the bible literally or metaphorically is a false dichotomy. There's exegesis which through study takes each passage as its written - some are literal, some metaphorical, some otherwise. There are also Christians who don't read the bible, or don't actually study, who tend to take for granted whatever their church-leaders say. Alternatively, some read the bible in context of their preconceived worldview.
3.) Creationist or Evolutionist has very little to nothing to do with morality. (Probably nothing)
4.) I don't think as many denominations differ in issues of morality as in other fundamental issues of Christianity.
5.) What would Mary ever have to do with morality?
6.) Are we looking at a 7-day creation? Only if the bible is involved.
7.) If any Christian doesn't answer the question "What's the most important rule(s) in the Bible for this morality?" and doesn't answer along the lines of "Love the Lord your God with all your heart and with all your soul and with all your strength and with all your mind; and Love your neighbor as yourself." hasn't been reading the bible very closely.
8.) However much prayer/bible reading/church involvement isn't strictly morality either, but as much bible reading as it takes to understand what the bible teaches about morality should be requisite.
9.) Ceremonial, traditional, and cultural issues of biblical times are not such great moral issues.
10.) There's only one bible, though many translations. Said translations do not differ enough in most cases to make more than a scholastic disparity. Besides, thanks to the internet, we can use all of them at the same time.
