You will absolutely and desperately cling with white knuckles against having to admit that any Church Doctor could have been wrong about anything.
Why?
Because once you admit that you have to admit that they theoretically could have been wrong about BoD.
And without your elevation of these Doctors to infallible status, you've got absolutely NOTHING to stand on.
Why? Because you have not ever made a single THEOLOGICAL argument in support of BoD. In fact, no one has. Without your reliance upon the authority of these Doctors, you've got absolutely nothing.
