Sarah Withrow King writes that God uses this vision to remind Peter that he is to "remove barriers of fellowship and to reconcile with those from whom we have been separated in order to further the reign of God on earth... the vision is one of radical inclusion". This interpretation is supported by (1) noting that there is no better way to get the attention of a hungry person than to use a vision involving food, and (2) there is no mention in the passage of what food is actually served, so we cannot assume that the vision is telling Peter that he must eat the unclean food when he visits Cornelius's house.
