(Acts 10:13) It is perfectly all right to eat unclean meats because God commanded Peter to do so.

1. This scripture does not say it is all right to eat unclean meats. It nowhere says Peter ate unclean meats.
    
2. Peter was in a trance (verse 10). What he saw was a vision (verse 17). He could. not have eaten any unclean animal.
    
3. Peter did not know what the vision meant (verse 17). He knew the law of clean and unclean meats was still in effect (verse 14). Peter had never eaten any unclean meats even though Christ had been crucified and resurrected for some time. He knew what God said in Leviticus 11 and Deuteronomy 14.
    
4. The key is in Verse 28. God said call no man common or unclean. The Jews regarded Gentiles as unclean and unfit for their company. God is using the unclean animals as a type of the Gentiles. The Gentiles are no longer to be regarded as unclean. We are all one in Christ.
