Does this scripture have a double meaning?

[FranciscoN2001]

"About noon the following day as they were on their journey and approaching the city, Peter went up on the roof to pray. He became hungry and wanted something to eat, and while the meal was being prepared, he fell into a trance. He saw heaven opened and something like a large sheet being let down to earth by its four corners. It contained all kinds of four-footed animals, as well as reptiles and birds. Then a voice told him, “Get up, Peter. Kill and eat.”
“Surely not, Lord!” Peter replied. “I have never eaten anything impure or unclean.”
The voice spoke to him a second time, “Do not call anything impure that God has made clean.”

I think this points to Jesus dying for the sins of every man and breaking the idea that only the Israelites can be saved. I think it also means that man can eat all food for the Lord has made it clean

I believe you are correct in that the meaning given to us by Luke follows in the story of the conversion of Cornelius. God is showing Peter in this dreams that through his mercy he has chosen to justify both Jews and Gentiles. As a result of this though, the distinctions between the Jews and the Gentiles (such as the prohibition of foods, Sabbath observation, etc.) have been fulfilled and are no longer required. As a side note, Mark, a close companion of Peter, gives this editorial when Jesus speaks about the fact that nothing that goes into a man can make him unclean.
