No, I definitely view certitude as an objective state. I am simply referring to the definition of what it mean to be certain.
If one recognizes that one can be in error on a judgement, that cannot be certitude.
Actually, you just proved a point that I made earlier in the thread, that the only means to be certain is to rely on an infallible source of truth.
The Church is that singular source for infallible truth on faith and morals.
Any departure from Church teaching in those matters, becomes fallible, and therefore, there can be no certitude.
