You are so blind it is truly amazing to witness.
HE HAS TO BE THE POPE IN THE 1ST PLACE in order to "contradict him for deviating from the faith".
You have destroyed the entire Bull to cling to a single sentence that you NEED to mean what you think it does at the exclusion of everything else so that you can continuing believing and acting as you do.
Francis was NEVER POPE TO BEGIN WITH ACCORDING TO THE BULL!
So, your misused quote that ignores the entirety of cuм Ex is 100% worthless. 
But I suppose your blindness in this regard is to be expected... What is even more amazing though is that you actually thought hashing this out on the other thread would make sense...
He was elected by all of the Cardinals, they accepted him as pope and we must also. You must first do what the enemies could not do - destroy the legal structure and hierarchy of the Church - you have to start there, that has to be your starting and ending point in order to believe he was never elected as pope in the first place.
This is proof positive that you are altogether wrong.
