As an atheist who is studying Christianity, the terms "Old Testament" and "New Testament" are neutral and academic terms to me. I know that they are unpopular with Jews. In the odd case in which I have to point out the flawed nature of the Christian scriptures, force of habit might lead me to slip up and say "NT" from time to time, but I will try my best to avoid it.
Are "Jewish Bible" and "Christian Bible" acceptable?
At the risk of being off topic, I would like to take this opportunity to thank everyone for making me feel welcome here. I look forward to learning from all of you in the future. L'Chaim! (or as my Irish ancestors would say, Sláinte!)
