Also, the line of reasoning used to prove that the pope is infallible bothers me. It goes in circles… How do we know the pope is infallible? Church councils say so. How do we know the church councils are correct? Pope so-and-so said so. But how do we know the pope is infallible? The Catechism says so. How do we know the Catechism is correct? The church wrote it. So how do we know the church is always correct? Well… the catechism says so, and so did the church, and so did a pope.
I’m coming back to the same question. How do we know?
The reasoning is not circular, but the objection indicates a failure to listen to what Jesus said and did.
**All four promises to St Peter alone: **
“You are Peter and on this rock I will build My Church.” (Mt 16:18)
“The gates of hell will not prevail against it.”(Mt 16:18)
I will give you the keys of the Kingdom of heaven." ( Mt 16:19)
First to St Peter:
“Whatever you bind on earth will be bound in heaven.” (Mt 16:19) [Later also to the Twelve].
Sole authority to St Peter:
“Strengthen your brethren.” (Lk 22:32)
“Feed My sheep.”(Jn 21:17).
How could these commands be fulfilled if Peter or his successors could TEACH error on faith and morals to the whole Church? Do you think that the Christ lied?
It was Christ who taught “Going therefore, teach all nations, baptising them in the name of the Father, and of the Son and of the Holy Spirit. Teaching them to observe whatsoever I have commanded you” (Mt 28:19).
And the promise was fulfilled: I will not leave you orphans; I will come to you." (John 14:15-18) “The Advocate, the Holy Spirit that the Father will send in My name, He will teach you everything and remind you of all that I told you.” (John 14:26) “But when He comes, the Spirit of truth,He will guide you to all truth. He will not speak on his own, but He will speak what He hears, and will declare to you the things that are coming. He will glorify me, because He will take from what is mine and declare it to you. Everything that the Father has is mine; for this reason I told you that He will take from what is mine and declare it to you.” (John 16:13-15)
St John counsels you: “We belong to God, and anyone who knows God listens to us, while anyone who does not belong to God refuses to hear us. This is how we know the spirit of truth and the spirit of deceit.” (1 Jn 4:6).
That’s how we know that the Pope is infallible when teaching the whole Church on faith and morals, as actually defined by Vatican I.
