"What God has made clean, do not call common" (v15). Peter’s vision turned his world upside down. The Law taught him to avoid all kinds of “non-kosher,” unclean meat, and now God Himself was telling him to eat these things. Peter was “inwardly perplexed” (v17), and so God repeated the lesson three times (v16). Remaining separate from foreigners, refusing to share a meal with them, would no longer please God; He wanted Peter to associate with the non-Jew, Cornelius, “without hesitation” (v20).
“Truly I understand that God shows no partiality …” (v34). God does not favor any nation or culture or ethnicity; we are all sinners saved by the “good news of peace through Jesus Christ” (v36).
