My challenges to my Roman Catholic friends: give me a convincing example of some doctrinal or ethical principle which make the following five criteria. Give me an example of some doctrinal or ethical principle that is (1) not already in Scripture; (2) not contrary to Scripture; (3) based upon what is properly identified as tradition (that’s what all these introductory questions were about); (4) is necessary in some sense to the Christian life or Church (necessary); and (5) could not have been revealed during the days of the Apostles.Any teaching on the moral dilemmae of out modern time would do, for example, the Catholic Church's teaching on abortion, cloning, artificial insemination, or euthanasia; or evolution and other scientific claims.If the Roman Catholic Church intends to be taken seriously when it tells us that tradition supplements Scripture, then it should be able to offer an example of something that is not in the Bible, that’s not contrary to the Bible, it’s part of what’s properly considered tradition, is necessary for the Church but could not be revealed in the days of the Apostles. We have to understand why it couldn’t have been revealed in the days of the Apostles! That’s the first problem that I would give to my Roman Catholic friends. Can you even give me a convincing illustration of something that matches all these criteria?
Well done.
