I have long enjoyed reading about both biblical scholarship and early Christian history. I find that some of the work referred to as biblical studies, or religious studies, overlaps with work called history. I would have thought of Fr. Brown as a biblical scholar, but you have also called him a historian (not that he can’t be both). When I first got interested in the topic, I listened to all of Mark Goodacre’s podcasts (lots of content, FREE on line, easy to understand), but Mark is a theologian who is a Professor of Religious Studies (I think), and I think of him as a bible guy, rather than a historian.
Can you illuminate for us the differences and boundaries between the related fields of biblical scholarship, early Christian history and whatever theologians call inquiry into the same material?
