The Pope is the Head of the Church. How, then, could the Church be an authority superior to the Pope?
To understand her regime, you have only to look at her beginnings. She did not emerge from any collectivity or community whatever. She was formed around Jesus Christ her Head, her Ruler, from whom all her life, perfection and power came to her. You have not chosen me, He said, but I have chosen you. Thus from the birth of the Church her constitution clearly appears. Authority does not reside in the community; it never passes, as in the civil order, from the community to one or to several heads. By its very nature, and from the very outset, it resides in a single recognizable prince. Since this prince is the Lord Jesus, who is to live and to reign yesterday, today, and for ever, it results that in natural right it was for Him and not for the ecclesiastical community to choose for Himself a vicar, whose role it would not be to represent the ecclesiastical community, born to obey not to command; but to represent a Prince, the natural Lord of this community. That, then, was what Our Lord Himself deigned to do when, having risen, before ascending to heaven, He chose, as St. John tells us, the Apostle Peter alone for His Vicar. And just as in natural right the Prince of the Church does not draw His authority from the Church, so neither does His Vicar, who depends upon Him and not upon the Church. (Cardinal Cajetan, Apologia de Comparata Auctoritate Papae et Concilii, cap. i, nos. 450-452)
"The Pope is the Head of the Church. How, then, could the Church be an authority superior to the Pope?"
He is a steward, not a potentate.
When I say "the Church" I am including the Church in its existence as the supernatural bride of Christ, as well as the Deposit of Faith.
If we accept your position, then we are left with the proposition that a Pope could order us all to worship Gaea as the Supreme Being through ritual prostitution and drunkenness.
