Pretty much, yes.

[daniel1212]

And how do you know that your judgment is correct that your church is the one true church and is necessary to know what is of God, but others are wrong in judging that she is not the one true church?

Pretty much, yes.

So "Pretty much" is how you know? Or are you basically arguing that an assuredly (if conditionally) infallible magisterium is essential for determination and assurance of Truth (including writings and men being of God) and to fulfill promises of Divine presence, providence of Truth, and preservation of faith, and authority.

And that being the historical instruments and stewards of Divine revelation (oral and written) means that Rome is that assuredly infallible magisterium. Thus any who knowingly dissent from the latter must be in rebellion to God?

The question was How do you know?

Any proof you can provide?

Crickets do not make a very good argument.

If what you believe were true, a good debater would not hesitate to show why.

If there is no proof, you are wrong.
