Damon Linker makes some interesting observations about the malleable nature of Christianity. I think his early history is not quite right (the early church had a stronger center than he represents – as though only at Nicea was a doctrinal boundary set). But as a historical observation, it is true that there are some distinctive variety in Christianity that does need some attention.
And here’s a response by Ross Douthat. Which clarifies the particular model of rights that Linker is speaking of (adult autonomy).
