Wikipedia's own account of the theory names Augustine (354-430), Duns Scotus (c. 1265-1308), William of Ockham (c. 1287-1347) and John Calvin (1509-1564) as presenting various forms of the position across more than a millennium, with no single founding text or date named anywhere in the article; this atlas records no origin-year fact rather than assign a false precise date.
What would resolve this A specialist historiographical judgment on whether Divine Command Theory names one continuous position traceable to a first articulation, or a family of related positions across many eras and traditions that should not share a single origin date at all.
