Acts 10:28 gives the authoritative interpretation of the vision: 'God has shown me that I should not call any man unholy or unclean' -- the vision is about Gentile inclusion, not food

Winger argues strongly that the meaning of the vision is about people, not food. Peter himself in Acts 10:28 says the vision taught him not to call any man unclean. Applying it only to food misses Peter's own stated interpretation.
