Through the Looking Glass
How so? Is Tertullian not allowed to have an original thought?
Sure. I'm just pointing out the the discussion of trinitas in the context of the diatribe against Praxeus suggests an ongoing debate about the idea of the Trinity that pre-dates Against Praxeus. Indeed, the biggest bone of contention in the document appears to be the doctrine of the Trinity. Could this be the first time anyone had ever written about the "Trinity"? Sure it could. I think it's the earliest known surviving reference to the Trinity by that name. I'm just saying the context of the document suggests it was already out there before Against Praxeus.
