How many of the believers in a literal interpretation of Noah's Ark also adhere to the dietary strictures imposed in the Old Testament? Surely any True believers eschew bacon, pork chops, ham sandwiches, Jimmy Dean's sausage, clams, oysters, and shrimp, right? It does say so in the Book, and if you're a 100% believer and have been ignoring this until now, why?
if you are truely interested, you might want to study the whole topic of Covenants. Christians are under a new covenant...one of Grace.
