This is often cited in catholic and orthodox circles to bolster the marian doctrines, as it entails the virgin mary had cells from Jesus in her body for the rest of her life.

Interesting that suddenly they promote one very specific finding from cellular biology so they can say "our religious belief is scientifically proven", but reject much more established understandings of embryonic cells when it comes to questions of e.g. abortion or origins of life.

I'd argue that science is not an a la carte menu where you can pick facts if they happen to support your argument...

I had no idea it was so common! Fascinating article, thanks for posting it.
