Rape and murder are clearly not universally detested; they are both widely practiced. Most of those imprisoned for those offenses in the U.S. profess to be Christians.
The crimes, "rape" and "murder" both contradict the Gospel message and NT, which says such things as, "walk in the spirit and you won't fulfill the lusts of the flesh". And, "he who hates his brother is a murderer". And, "do no murder".
A person can, "profess" to be anything, but if their actions contradict that which their professions are defined by, then they are not what they claim.
For example, if I claimed to be an atheist, and prayed to God every night in sincere belief, this would mean that my professions contradicted my actions.
You should also note that there are a lot of Christian prison-programs where prisoners are told the gospel, and will LATER, profess Christianity, after hearing. Whether this is a true repentance, depends on their fruit later on.
So your definition of "Christianity" has to be a blanket definition, with no meaning.
for Christians who hold the Bible to be inerrant, rape and murder are universally endorsed.
You haven't stated one of the premises of your argument, which is,
"if it is accepted that my interpretations of the bible are correct and we all agree on them."
- I hold it to be inerrant.
- I don't hold that rape and murder are endorsed
But in an atheist, evolutionist, world, "rape and murder" are the same as, "eating ice-cream", because materialistically speaking,
both are just an interaction of particles. So why didn't you accuse Christians of eating ice cream, if your world is true?
You APPEAL to morality, but again, what is morality except a set of preferences between your ears, and those who agree with you?
Your Bible records your God instructing his people in their use; since that God is, to you, the sine qua non of universal, one would have to say that, for Christians who hold the Bible to be inerrant, rape and murder are universally endorsed.
Premise 1. "your God instructs such things." (an atheist interpretation)
Premise 2. God is held as universally acceptable.
ERGO Christians accept rape an murder.
Premise one is incorrect, we don't accept that God, "instructs rape and murder." There are many theological reasons that pertain to what Christians accept.
If I were to say, "God condones rape and murder" since I define myself as an accepter of an inerrant bible, because it says, "do not murder" I would break the definition of what it means to believe in inerrancy, if I were to conclude that He condones it. Therefore I would not really accept an inerrant bible. Therefore someone that accepts an inerrant bible, CAN'T do what you say
WITHOUT NOT being an inerrantist. Thus your argument is a contradiction in terms because I have to be both an inerrantist, and a none-inerrantist for your argument to hold water.
It's like saying, "as an eater of only genuine food, you accept that none-genuine food is food, therefore you eat none-genuine food."
But to accept none-genuine food would mean I don't "only accept genuine food." So I would be both X and NOT X, which breaks the law of non-contradiction.
As inerrantists, you forget that we hold the bible inerrant, which means when it says God doesn't condone sin, or sin, we have to accept it, or NOT BE inerrantist, BY DEFINITION. So if He kills or recommends an ugly action, as He does at times in the OT, then He can only be doing it for an ultimately righteous reason.
