Is is proper, in the context of this site, to use Christian or other non-Jewish sources (for example, secular Biblical scholars) in answering questions, particularly exegetical questions?
On the one hand, this is a site about Jewish learning and tradition, and questions about the understanding of some text are essentially questions about how Jewish tradition understands said text. Using Christian (or other non-Jewish) sources would then not be a valid answer.
On the other hand, many Jewish scholars throughout the ages (notably Isaac Abarbanel) have used Christian sources (and of course vice versa) to help understand and consider certain approaches to the text at hand. It may not give you the traditional Jewish approach to the text, but it may very well be the correct approach. In search for the truth, one must accept all sources.
So, what is the appropriate approach for this site?
