I don't have any religious beliefs.
Peter's vision is an analogy.
It's more about God making the hearts of the Gentiles clean and that Peter should accept them, notice it is part of a story in which Cornelius comes to meet Peter and he invites him into his house (which would be unusual for a Jew and a Gentile at the time due to them being considered unclean). It makes sense in the context of the whole chapter.
Like you said, the unclean/clean issue was more to do with people and that those who were once considered unclean should be accepted. This does relate to the food issue in that those who were not Jews were not expected to follow the Jewish laws (which were only intended for the 'chosen' people in the Old Testament, not people of any other nation).
I know muslims have a huge beef with Paul and his corruption of the teachings, but it is in Acts 15:5-11 where the Jews are told that God accepts the Gentiles without them following Jewish law.
It is Peter who told them and Luke who wrote this part of the Bible, so how can you say it is Paul trying to persuade people not to follow the jewish laws?
see, hear we'd tell you that there is no indication prior to the late 2nd century who the author is and the PRIMARY ISSUE at hand seems to be circumcision! there's no "yoke" affiliated with keeping kosher, over a BILLION people keep a "halal diet" and is not difficult.
actually my belief in THIS matter predates my Islam. most of my views came from Herbert W Armstrong's writings, hence the "heretic" nic under my name as the Christians on this board don't consider him a Christian.
Peace be upon those who follow the guidance,
i reckon we look for little gems of the truth in the NT!
