I suppose this would be a whole new thread, and I don’t know if anyone (including me) is up for it, but I think a careful consideration of Jesus’ genome, along with some (I think) basic historical Christian theology, need not be unsettling. The only unsettling thing I can think of is the one you were probably alluding to: the fact that Jesus’ genome, and especially his Y chromosome, would identify his father. I mean in principle, of course, since I don’t see how we can expect to have DNA from the human candidates (Joseph et al.). Maybe his Y chromosome would somehow say “god” but I don’t know how that would work.
Given the number of relics claimed to come from Jesus’ body (including his foreskin, now there’s a nice unsettling thought), we might wonder if we have access to some of his DNA. I don’t personally find any of the relics credible, but it’s not biologically/physically ridiculous to think that some of his DNA is still intact on earth.
