What would happen if the Holy Father restated some salient items of Catholic dogma?
First of all, I am thinking about this dogma: Extra Ecclesiam Nulla Salus. This is defined as follows: “We declare, say, define, and pronounce that it is absolutely necessary for the salvation of every human creature to be subject to the Roman Pontiff.” (Pope Boniface VIII, the Bull Unam Sanctam, 1302.) If Pope Francis repeated this, one can only guess at what might happen. At the very least he would utterly destroy 60 years of ecumenical dialogue and cause a massive internal rift within the Catholic Church. He may even have to go into hiding!
