Is reference to the Bible circular in nature?
1) In the context of a court room evidence–which is the context of today looking back 2000+ years–the idea of circularity is distinctively different.
2) All worldviews are generally circular unto themselves. Thats the nature of paradigm shifts and ways of viewing the world.
3) The are internal proofs in the Bible.
4) The historical evidence of Jesus is pretty compelling as a source of external justification.
5) Provide additional justifications based on commonly accepted beliefs about how the world works. This is typically what many apolegists tend to do in combination with other methods.
6) Using the methods of logic–cause and effect relationships, metaphors, analogies, and experiential evidence. Arguably these can even help provide some kind of justification for the spiritual and mystical nature of reality–a reality beyond just materialism–that open up the possibility of realms and reality beyond reductionist science
7) Ultimately some issues may need to rely on faith. But all worldviews have some element of faith.
8] Oxford Theoretical physicist Ard Louis has a notion of a tapestry of Truth. The Christian faith is grounded on a tapestry of integrated ideas and proofs.
9) I’m not sure if any of these specifically address this issue, but Resources about Biblical Authority . I might particularly look at the work of NT Wright, as he’s a widely trusted philosopher and theologian.
10) The nature of logical fallacies is heuristic–not eliminative. This is pretty key. Its also the reason why #5 is true.
11) There are multiple authors to the text. This is an integrative proof. For instance, you have a number of apostles and minor prophets, all who write books. They should be treated as independent texts for the purposes of a proof like this one.
