Romans 14:2-4

For instance, a person who has been around for a while might well be convinced that he can eat anything on the table, while another, with a different background, might assume he should only be a vegetarian and eat accordingly. But since both are guests at Christ’s table, wouldn’t it be terribly rude if they fell to criticizing what the other ate or didn’t eat? God, after all, invited them both to the table. Do you have any business crossing people off the guest list or interfering with God’s welcome? If there are corrections to be made or manners to be learned, God can handle that without your help.
