The Pope is the successor of Saint Peter. When there is a dispute about a Dogma, the Catholic Church believes the Pope will be guided by the Holy Spirit in defining a Dogma from the chair of Saint Peter. Most Popes never define a Dogma Ex Cathedra, hence, most Popes never exercise Papal infallibility.
I have no idea what some of the words you used there mean, excuse my ignorance, however, they are words that, to me, are meaningless anyway. But thanks for the info.
