The very same paragraphs talk about it being comparable among early Christians to such 'grave sins as contraception and sterilization'. How should this inform the relative weight of the use of condoms and murder, for contemporary Christians?
This doesn't at all support the notion that Christianity has always been concerned with abortion as a corrolary to murder, which is at the center of contemporary conservative religious discourse on the issue.
Maybe so, but apparently it's been condemned from the earliest times in Christianity: https://en.wikipedia.org/wiki/History_of_Christian_thought_o....
I don't really know the Bible, but I'm guessing Jesus probably didn't spend a lot of time condemning literal murder either, so it's probably not safe to assume that means he thought preventing greed is more important than preventing murder.
