In a vision, Peter was once instructed to eat unclean beasts (Acts 10:11-13). As in the case of John in Revelation 10, Peter himself was to illustrate the experience of God's church. Eating a thing is to receive it. Beasts in prophetic visions symbolize kingdoms and nations (Daniel 7:17, 23). Through this dream God was instructing the church to receive into itself people of "every nation." Acts 10:35.
