Rom 14:5-6
One man esteems one day as better than another, while another man esteems all days alike. Let every one be fully convinced in his own mind. He who observes the day, observes it in honor of the Lord. He also who eats, eats in honor of the Lord, since he gives thanks to God; while he who abstains, abstains in honor of the Lord and gives thanks to God.
In his next instructions to the Christian community of Rome, St. Paul intends to avoid unnecessary discord. It is important to distinguish whether what is at stake is the truth or simply differing opinions. The truth must be firmly defended. On the other hand, differing views can be allowed in second-order matters and should not give rise to quarrels. Evidently, there were disputes in the Christian community about whether meat could be eaten. It is likely that it was especially the Judeo-Christians who were concerned about this issue, since meat could have been sacrificed to idols.
