The Pope alone cannot do it, but the Pope and the Magisterium can inact whatever changes they want over time. The fundamental problem is thus. The RCC presumes that “The Gates of Hell” cannot prevail against the leadership of the church (because for that to occur in the RCC would imply that Hell HAS prevailed since the leadership collectively can shape the Doctrines and Dogmas of The Faith). It is an ominous sign, however, when the Pope, those who elected him, and much of the hierarchy openly support such things.
An apostate church acting with apostasy. No big surprises
No earthly power...not the Pope nor the magisterium nor any one else...can alter the doctrine of the Catholic faith one iota. Period. End of story.
It is not the Pope’s Church, it is not the “Magisterium’s” Church (as you refer to it), it is Christ’s Church. And Christ’s Church doesn’t change.
Plenty of people “dreamed” of something different than what the Church taught. They didn’t get anywhere, and neither will this idiocy.
