Oh, sorry for misremembering the original context!
“Theological constraints” seems to me to be simply descriptive, not intended to be insulting. Would the phrase “theologically rigorous” have been similar in meaning to you?
I felt the need to look up ‘monogenism’ right before reading this comment, funnily enough. Apparently it means “common descent for all human races,” and although it was a big debate a century or two back, it is actually a topic on which Darwin, modern science, and the Abrahamic religions agree, at least in the broad sense that we are all descended from the same gene pool, whether it was two people or a population.
I’ve actually been thinking about starting a topic related to this. It seems to me that Genesis does not describe Adam and Eve as the first humans, but that there is a long tradition of conflating Genesis 1 & 2 into the same story. I wonder if this was driven by the moral desirability of emphasizing that all humans are related and no group is inherently ‘better’ than the others. And having asked that question, can we then ask if we need to continue to tell each other that Adam and Eve were the sole progenitors of the human race in order to not be racist (bleep)s to each other? This is perhaps a ‘constraint’ of the sort you are asking about, I suppose. What do you think?
