One could say that the texts of a religion, such as the Bible in Christianity, do provide a general "moral framework" expected of its adherents. Many religions prescribe some sort of framework like this, as vague or as contradictory as it may be.
The idea of "sin" is huge in Abrahamic religion, so the fact that their texts particularly describe what is "sinful and not" I think is a clear-cut sign there is some sort of set of "values" that religious adherents are expected to have.
Not that I agree with said frameworks or give any authority to the texts- and also understand that many forms of these religions interpret the texts different ways, which cause various splits in what is considered moral or not. Additionally, I understand that it is mostly futile to expect most religious people to follow the prescribed morals of their religion or denomination, as it always seems to end up that people have their own specific personal set of morals, and then they just try to rationalize or stretch it to fit whatever religion or worldview they adhere to
Or is your point more that while religions DO have expectations like this- the moral "rules" of these religions don't originate from the religion itself, but instead are general moral values adopted, altered, or shared by many religions? If so, then maybe we are in agreement and I am talking past you.
