The reading is from Acts of the Apostles 10:44-48; 11:1-10

In those days, while Peter was still saying this, the Holy Spirit fell on all who heard the word. And the believers from among the circumcised who came with Peter were amazed, because the gift of the Holy Spirit had been poured out even on the Gentiles. For they heard them speaking in tongues and extolling God. Then Peter declared, "Can any one forbid water for baptizing these people who have received the Holy Spirit just as we have?" And he commanded them to be baptized in the name of Jesus Christ. Then they asked him to remain for some days. Now the apostles and the brethren who were in Judea heard that the Gentiles also had received the word of God. So when Peter went up to Jerusalem, the circumcision party criticized him, saying, "Why did you go to uncircumcised men and eat with them?" But Peter began and explained to them in order: "I was in the city of Joppa praying; and in a trance I saw a vision, something descending, like a great sheet, let down from heaven by four corners; and it came down to me. Looking at it closely I observed animals and beasts of prey and reptiles and birds of the air. And I heard a voice saying to me, 'Rise, Peter; kill and eat.' But I said, 'No, Lord; for nothing common or unclean has ever entered my mouth.' But the voice answered a second time from heaven, 'What God has cleansed you must not call common.' This happened three times, and all was drawn up again into heaven."
