Archbishop Rowan put it like this, "The relationships between Jews and Gentiles in Acts is not simply that of one racial group to another. It’s a story about what faith really is and what salvation is. Be circumcised, keep the law and you will know you have the signs that make you acceptable to God. To which Paul and Barnabas and the Church replied, there is no sign by which you can tell in and of yourself that you are acceptable to God. There is nothing about you that guarantees love, salvation, healing. But there is everything about God in Jesus Christ that assures you and so if you want to know where your certainty lies, look to God, not to yourself".Read the whole thing. It's all good.
This has direct relevance to gay and lesbian people condemned by the cultic rules and purity codes of Leviticus. It can be argued that since the cultic rules and purity codes were put aside in accepting Gentiles so now Christians can put aside those codes which deal with sexuality. As Ian Duffield puts it "to exclude homosexuals on the basis of the same kind of purity laws constitutes a reversion to a form of religion which Jesus encourages us to leave behind". (Expository Times Volume 115, No 4, January 2004). A simple appeal to scripture turns the Bible back into a law book and it is St Paul who argues against using the Old Testament in this way. It would be ironic therefore if his letters were to be used for a purpose he condemned.
