Just like protestants who claim the guidance of the Holy Spirit in their interpretation of the Scriptures...
Oh sure, y'all don't claim infallibility in principle, but you sure claim it in practice.
We are asked to believe the Holy Spirit can guide Pastor Billy in his reading of scripture—or any of the worshipers in Billy’s worship center—but the Holy Spirit CANNOT guide the leader of Christ’s own Church on earth—and Vicar of Christ—in teaching Christian doctrine.
In other words, we are expected to believe the Holy Spirit is an anti-Catholic bigot.
What was that old joke about man re-creating god in his own image?
