You're listening to the SSPX podcast, and welcome to episode 37 of the Crisis in the Church series.

We'll finish our discussion from last week, all leading to the main question of these two episodes.

How can the church, which is indefectible, give us a right of worship, which is defective?

Last week, we looked at how the church could, in fact, promulgate errors through an ecumenical,

And this is an important question for us. Now, we looked at, in the first episode, we looked at infallibility in some detail. And we started to look at disciplinary infallibility. Now, if you

haven't already, I'm talking to our listeners, if you haven't already seen that first episode, it might

be good to at least read through it. We do also have some notes on our website on sspfxpodcast.com

slash crisis that you can review as well. But we're going to dive into the second part here, Father,

which is what does the Magisterium of the Church say about disciplinary infallibility?

That's where we start with this section, right, Father?

Absolutely.

And it's a crucial question because, of course, the theologians themselves, when they write

on these subjects in their manuals, they're looking primarily to what the Church herself
