Some of my colleagues pointed that quoting from the Bible is not good in an academic article. What is your opinion about that and I would like to know whether there are any norms regarding quoting from spiritual texts?
There are some fields where it is obviously appropriate, such as academic articles about middle eastern history, ethics, English literature to name a few. I think Mr Paul needs to be a lot more specific about the field and the nature of the questionable quotes.
In the academic study of religion, as long as you simultaneously establish the historicity of what you're quoting, you not only should but must quote from the Bible. Let's say I was studying John 14:6. I could validly quote it if I made an argument, based on the criterion of multiple independent attestation (with Q 10:22), that Jesus actually uttered it. But I couldn't validly quote it if I just assumed that Jesus said it because it's in the Bible.
I think if it is relevant, there is no problem, I have seen a PROF. of mycology quoting from the bible for his inaugural lecture but for academic exercise especially in Sciences, it may not fit in properly. However, those in religious studies are in the best position to do that
