You need to understand what the definition of infallible is and when it is used in the church. What infallibility does do is prevent a pope from solemnly and formally teaching as “truth” something that is, in fact, error. It does not help him know what is true. He, along with the Bishops keep the deposit of faith since the early church.
The pope doesn't know what is true?
A child could answer that one.
It is staggering that Catholics continue to defend the church and the pope, which is so far off the rails, clinging desperately to the hope that someday, somehow, things might get better and go back to the good old days, which nobody can seem to agree on what it even is.
V2?
Trent?
Some council in between?
The EO who claim THEY are the original Catholic church and Rome is in schism?
And this is somehow supposed to be an example of how the church is protected from error in faith and morals and they are *keeping the deposit of faith*?
What faith?
I suppose it depends on if you ask a sedevacantist, a traditionalist, or a post V2-ist, or some other private interpretation of Catholicism.
Psst, you CAN know the Truth and it doesn't take a pope or council of bishops or some ex cathedra pronouncement to find it or know it.
And it's simple and will set you free from the convoluted morass of rules and regulations and sacraments and legality that any church would impose on you.
Huh?
And how do you know that what the pope and ecumenical councils in union with him ever formally define is infallible? Because it has been defined by such a council, thus categorizing their assertion of ensured infallibility as being assuredly infallible.
Next question: Is this ensured magisterial infallibility essential for knowing what is God?
And what is the basis for this? Does being the historical magisterial discerners and stewards of Divine revelation, and inheritor of promises of God's presence and preservation mean that such must be infallible?
