The events in Acts 10:44-48 occurred as part of Peter’s first sermon to the Gentiles. Peter received a vision from God. In that vision, a sheet unfolded from heaven. On that sheet were animals of all kinds, including animals that were unclean under Jewish law. God commanded Peter to eat, but Peter refused because of Jewish dietary laws. God replied that He has made these animals clean and what He made clean could be eaten. This vision was a metaphor for God’s command to expand Christianity to include the Gentiles, who were also considered to be unclean by the Jews.
