19So we should always eagerly try to live in a way that will cause peace among fellow Christians, and we should try to do what will help each other to mature spiritually.
20Do not destroy what God has done in the life of any believer just because of your eating certain kinds of food MET which that person considers wrong to eat! God permits us to eat every kind of food. But if, by your eating certain kinds of food, you encourage another person to sin by doing what he believes is wrong, you are doing wrong.
Romans 14
Romans 14:19-20
