Still, there were decisions made by the Constantinian church which decided what would be "scripture" and what would be "apocrypha". And I certainly do not believe that those decisions were all divinely directed.
My personal system is:
1. Read the words and works of Jesus Christ.
2. Read the rest of the Bible.
3. If an interpretation of a particular verse or passage contradicts the words and works of Jesus Christ, reject it. Same for any doctrine based on such verses.
Sadly, most Christians won't follow this system, because if everyone bases their doctrine on the words and works of Jesus and refuses to compromise that position, it would completely destroy church organization and church government as it exists today. And it would also require every Christian to oppose the state, at least in principle - and we all know that's not going to happen. As I said when I called last week, most Christians will support the state, even if it means rejecting Christ-centered doctrine.
I'm writing a book about that called Christ and Liberty. I expect to be roundly denounced as a heretic when I publish it. Should be fun.
