And the Bible sanctions all sorts of nasty acts towards non-believers.... but that's exactly why we don't discuss religion in lodge and why we don't restrict certain religions. Messages taken out of context could mean anything. I don't recall ever seeing L. Ron Hubbard making such sanctions, not saying he didn't, but regardless even if I had, without knowing a heck of a lot more I would not necessarily trust that because the founder of the religion made such a statement that it necessarily meant the followers believe that.
In the end it should come down to does the man believe in some form of deity, and is he a worthy man. His specific religion is not really important, he could believe in the Flying Spaghetti Monster for all I care, as long as he is sincere in that belief.
