Theology, I have tried to point out, isn't prone to being tested.

I got that.
Still, theology is being a faculty. Would you like to erase it from the field, so it cannot be further something one shall be able to study? So, from your point of view, all topics need no further study which cannot be tested to be true or false. As a consequence, all religion needs to be eliminated?

What practical impacts of that being the case, do you see will happen, if religion is gone? Philosophy shall go? History shall go? What about arts? None of them fit to the method of clean proof and disproof.
No churches, no chapels, no religious communal gatherings, no songs, no prayers? Where then to find the words to farewell someone who died and whom you loved? No need in doing that? What kind of dignity shall be practiced instead? Do you have a substitute? Or is no substitute needed?
