Jeff, 
 
My question is: why do today's leaders apply a stricter view of the Word of Wisdom than the founding church prophets? 
 
I know the Mormon church holds the Word of Wisdom and Book of Mormon as higher authority (especially, when there's a contradiction) than the Bible. Yet to compare the Word of Wisdom to the Ten Commandments is misleading. The Ten Commandments don't directly address health issues, unless you're thinking of murder or committing adultery as health issues, but those aren't diet related. And it's wrong to imply the Ten Commandments are outdated, as if murder and stealing are okay in today's environment. 
 
Any way, the original church prophets veiwed the Word of Wisdom as suggesting moderation, not as prohibitions or commandments. If God gave the Word of Wisdom in the context of time and situation, then He should give a new Word to make a change. But he didn't give a new Word, only the interpretation of the original Word of Wisdom changed. Why? 
 
Thanks. Sam.
