So, whether you eat or drink, or whatever you do, do all to the glory of God.
1 Corinthians 10:31

Although, sacrificing an otherwise clean animal to a pagan god doesn't necessarily make the meat unclean, eating meat that actually *is* unclean or participating in the pagan ritual itself, including the ritual eating of the animal, is a sin and cannot bring glory to God in any way. It is impossible to glorify God by doing that which he has forbidden.
