I just found this forum (it’s a discussion of Russian paleontologist with some creationists) and checked it (http://macroevolution.narod.ru/discussion.htm - but it’s in Russian, of course). Yes, this participant referred to himself as Christian and yes, he said that death for Christians is unnatural („противоестественная”). He didn’t mention his confession, though. Why, wasn’t death the consequence of sin, according to Bible? Weren’t all creatures before the Fall sinless, hence immortal?
(I just wondered about why creationists don’t accept evolution as God’s activity, and this post seemed an explanation to me).
