I think this is a misrepresentation of Paul says. I refer you to Romans 12:1 where your body is not your own but a holy sacrifice to God. But you should note there will be NO bacon in Heaven. No meat in any form of course. The original (Edenic) diet was fruits and herbs and the same will be in Heaven. There will no more death or sadness in Heaven which eliminates kids playing with Bambi in the morning and watch her slaughtered to be eaten for dinner. But go and do as the Lord directs you.
There is absolutely no mention of meat here, clean or unclean.
