Because you said that no one can be 100% infallibly sure of sacramental validity. I wasn't asking about infallibility previously. Maybe you just used the term to prove a point, but the Church is precise in her language.
I'm 100% sure that +ABL's consecration is valid. Notice that I'm not saying anything about infallibility. So does that mean that I'm going against Church teaching in your opinion?
I was discussing and distinguishing between moral and infallible certitude, because some seemed to think that since I insisted that only moral certitude was available regarding sacramental validity (which is a lesser threshold than infallible certitude), I was thereby calling Msgr. Lefebvre's Orders into question.
Nothing could be further from the case.
As regards your own subjective certitude, I am aware of no cause which should disturb it.
