Romans 14
It seems that Paul is mostly addressing the manner of how we come together and eat. Food seems to be the main topic here and it seems to be a really important matter.
I imagine eating together is like a party, a celebration, or a special occasion. Just like Jesus had his last supper before he died.
Ultimately, it is the same message: building one another up, living in peace with each other so we may all be strong and be ready to give an account to God.
The main point is not to be condemning to the believing brothers, but to help or be mindful to keep them strong. We have to encourage them to do what is right rather condemning them because they are not "strong" enough.
Paul refers to situation like these as "disputable matters."
To God be the Glory.
