Apparently when people try to claim that Jesus was somehow still alive after being crucified and having His heart speared, and you point out that not only was he dead, but as dead as a package of meat in the supermarket (given that whole “blood and water” thing) — it offends people.
I’m not really sure how somebody flirting with Docetism can be offended by that. But I guess that’s the whole point of all the Docetist-type heresies. People would rather believe that Jesus faked His death or never had a body or somehow managed to escape suffocation and bleeding to death through hibernation. They don’t want to believe in Christ dead on the Cross. They want the befores and afters, because they are prettier. They don’t want the scene inbetween, even though that’s the crux of matters.
