I was starting to write a question about the history of a certain theological definition, and when I went to add tags all I could find relating to history was Church-History. Granted they are related, it is not entirely accurate. Church history is concerned with history about the actual people and organizations in the church through time. Meanwhile:
Historical theologians are thus concerned with the historical development of theology. 1
I most definitely want history that focuses on the theological term and it's definition through time. People and groups from church history are necessarily involved, but the focus is not on them.
Should I just use church-history and hope I make it clear enough in my question? I don't think that is the best solution.
I've also noticed a few times that questions can get confused between biblical basis or historical theology. That it is unclear if the one asking is looking for the scriptural origins or the historical origins of a doctrine held by X denomination.
For example, According to Protestants, where does the idea of Jesus being "one substance with the father" come from?, the original OP asks for the "origin" of a belief, tags it just trinity and Protestantism, and later gives a self answer that summarizes its theological history. But before he self answered(I think?), it was edited with the biblical basis tag. The title is now edited to be a biblical basis question, based on the tag. But what if the OP had intended it to include historical theology (which can include both scriptural and historical reasoning)?
Another example here, Q: When and why did the modern literal 6-Day creation theory become popular?, is clearly looking not just for history but for theological history.
Adding a [Historical-Theology] tag, combined with the existing church history and biblical basis tags, would cover more possibilities more precisely. I understand it may not get used a lot, but I for one would subscribe to it.
Origin questions that are not focused on "Who was the first" but are focused "when" or "what"
Abstract questions that don't fit Origins, era (since that may be unknown) or even church history:
