Romans 14:1Accept him whose faith is weak, without passing judgment on his opinions.a 2For one person has faith to eat all things, while another, who is weak, eats only vegetables. 3The one who eats everything must not belittle the one who does not, and the one who does not eat everything must not judge the one who does, for God has accepted him. 4Who are you to judge someone else’s servant? To his own master he stands or falls. And he will stand, for the Lord is able to make him stand.
5One person regards a certain day above the others, while someone else considers every day alike. Each one should be fully convinced in his own mind. 6He who observes a special day does so to the Lord;b he who eats does so to the Lord, for he gives thanks to God; and he who abstains does so to the Lord and gives thanks to God.
7For none of us lives to himself alone, and none of us dies to himself alone. 8If we live, we live to the Lord, and if we die, we die to the Lord. So whether we live or die, we belong to the Lord. 9For this reason Christ died and returned to life, that He might be the Lord of both the dead and the living.
10Why, then, do you judge your brother? Or why do you belittle your brother?
The refusing to eat meat Paul references in verse two has to do with that Christian’s religious beliefs, as does the abstaining from observing certain days in verse five. In these verses Paul’s direction to Christians is not to judge other Christians who have different beliefs about scripture, up to a point, even if we know they are wrong. So do you have to believe everything your pastor, your elders, your church Father, your Pope, or your denomination teaches about scripture in order to retain God’s favor? Not according to these scriptures. And like Christ you can choose to sit next to other followers of God who share opposing views on biblical topics. To say you cannot is unchristian, because even Christ did that.
At 1 Corinthians 1:10 Paul was not contradicting what he wrote to the congregation in Rome. The speaking in agreement and being of like mind he wrote about had to do with not forming factions inside the church groups by raising one Christian teacher over another. His words related to that behavior only, as you can see here:
“I appeal to you, brothers, in the name of our Lord Jesus Christ, that all of you agree together, so that there may be no divisions among you and that you may be united in mind and conviction. My brothers, some from Chloe’s household have informed me that there are quarrels among you. What I mean is this: Individuals among you are saying, “I follow Paul,” “I follow Apollos,” “I follow Cephas,” or “I follow Christ.”Is Christ divided? Was Paul crucified for you? Were you baptized into the name of Paul?”1 Corinthians 1:10-13
You are not alone. If you do not believe everything about scripture your denomination is teaching, someone sitting next to you might share your same thought. And Christ might share your view, not theirs. But if not, Paul’s letter to the congregation in Rome shows Christ does not abandon you for having an incorrect view on applying scripture.
