Well...this is just my personal opinion, but if you are trying to help spread JOS by translating some of its content into another language so people there have the opportunity to learn about Satan, I don't see how that would be a bad thing...so long as you translate truly without changing any of the original content.....I think it would be a great initiative for you to take. I would think Satan would appreciate that...In the Al Jilwah Satan says:
"I am ever present to help all who trust in me and call upon me in time of need. There is no place in the universe that knows not my presence."
I would think if there is no place in the Universe that He does not know, then in Viet Nam, and in Vietnamese Father will understand you! LOL.
But its not my call. I suppose a HP must answer that?
or another Satanist who knows more than I do about such protocol?
Hail SAtan!
