You are reading this from a 21st century modern american viewpoint that does not believe that God created any days as holy or sanctified.

Are we to believe that under some other viewpoint, "One person regards one day above another, another regards every day alike. Each person must be fully convinced in his own mind. 6 He who observes the day, observes it for the Lord, and he who eats, does so for the Lord, for he gives thanks to God; and he who eats not, for the Lord he does not eat, and gives thanks to God," means that we must observe certain days and must not observe others? Postmodernism, anyone?

Read it however you like. There's only one correct interpetation though.
