Romans 14:5 "One person esteems one day above another; another esteems every day alike. Let each be fully convinced in his own mind. 6 He who observes the day, observes it to the Lord; and he who does not observe the day, to the Lord he does not observe it. He who eats, eats to the Lord, for he gives God thanks; and he who does not eat, to the Lord he does not eat, and gives God thanks. 7 For none of us lives to himself, and no one dies to himself."
Keeping the context... in mind once again the followers of Jesus were essentially a new religion. Those who had been Jewish were embracing Jesus as the Messiah while the majority of the Jews did not. The rest of this new religion we call Christianity was made up of Gentiles or essentially everyone and anyone who wasn't previously Jewish.
This created two major dynamics. First within the former Jews there was a difference of opinion about how much of their Jewish customs they should keep. There were feasts and special holy days and Sabbaths beyond the weekly Sabbath. Some felt these should still all be observed. Some felt the opposite.
Add to this the Gentiles who never had any of that background to begin with and it's quite a cultural mix. As we talked about yesterday the Gentiles and Jews also struggled with meat that had been sacrificed to pagan idols before being sold in the market places.
What to do? Again Paul does not solve the issues by picking sides. He advocates for two basic things. First in your own decision making follow your conscience before God. Secondly practice love and mutual respect. For example you may feel eating meat sacrificed to idols is ok. That's fine. However don't bring it to a church function or serve it to guests in your home if it is an issue for them.
Love would never do something like that. We'll explore this tomorrow as Paul goes more thoroughly into the subject. See you then.
