“I should not call any man impure or unclean”
You know how unlawful it is for a Jew to associate with a foreigner or visit him. But God has shown me that I should not call any man impure or unclean. (Acts 10:9–28 BSB)
What it sounds like today
A vision about food that suddenly becomes a policy about people.
The cultural key
The sheet of unclean animals ('kill and eat') strikes at the kosher line of Leviticus 11, but notice Peter's own decoding: not a word about menu, everything about company. No written law actually forbade entering a Gentile's house; that was the protective fence of custom (the same instinct as John 18:28, where priests will not enter Pilate's headquarters). The word BSB renders 'impure' is koinos, literally 'common', the technical purity term: profane by contact. Peter connects the dots aloud: if no food defiles the eater (the lesson Mark 7:19 drew from Jesus), then no table defiles the guest, and no person is off the visiting list.
Recovered meaning
The vision's punchline is a sentence Peter says in a Gentile's living room: God told me to stop sorting people into clean and common. The food laws' social function, keeping the peoples separate at meals, is retired by the same authority that wrote them.
