What we’re willing to eat and drink with other people (not just tolerate the presence of, but participate in) has such deep significance. It says,
You are clean, and what you eat is clean.
You are with me, I am with you.
What you touch, I will touch.
What you eat, I will eat.
What you drink, I will drink.
Otherwise a theological and practical wall is raised between us and others. In this light, consider the significance of God showing a “sheet” to Peter with “all kinds of animals and reptiles and birds of the air.” God says to him:
“Rise, Peter; kill and eat!” (Acts 10:13)
Go preach the precious gospel of Jesus to Cornelius, and have table-fellowship with him, and eat what he eats!
There is precious reconciliation in Christ at the dinner table:
“For [Jesus] himself is our peace, who has made us both one and has broken down in his flesh the dividing wall of hostility by abolishing the law of commandments expressed in ordinances, that he might create in himself one new man in place of the two, so making peace, and might reconcile us both to God in one body through the cross, thereby killing the hostility.” (Ephesians 2:14-16)
And don’t let anyone give you trouble:
“Therefore let no one pass judgment on you in questions of food and drink, or with regard to a festival or a new moon or a Sabbath. These are a shadow of the things to come, but the substance belongs to Christ.” (Colossians 2:16-17)
The inverse is also true: What other believers are sensitive not to eat, we are, in their presence, sensitive not to eat. Accommodate for the sake of love:
“It is good not to eat meat or drink wine or do anything that causes your brother to stumble.” (Romans 14:21)
