The papacy is not a plaything that can be passed between ‘liberal’ and ‘conservative’ factions every time there is an election. Only men who fulfill the criteria that Our Lord established can ever occupy it. The pope must be Catholic. The pope is always Catholic.

This Church has had an unbroken line of succession from Peter himself; these legitimate pontiffs are the heirs and defenders of the same teaching, rank, office and power. And the Church is where Peter is, and Peter speaks in the Roman Pontiff, living at all times in his successors and making judgment, providing the truth of the faith to those who seek it. The divine words therefore mean what this Roman See of the most blessed Peter holds and has held.
For this mother and teacher of all the churches has always preserved entire and unharmed the faith entrusted to it by Christ the Lord.
