I have lately been struggling with doubts about Catholicism. I have wondered about the possibility that the claims of Eastern Orthodoxy are true. What are the arguments and the evidence for papal infallibility (from reason, history, church fathers, or scripture)?
Read about the Council of Jerusalem in Acts 15. When Peter made his decision, he made base on what God showed him in Acts 10. That is the teaching of Papal Infallibility (the Holy Spirit guides the Pope to make an infallible decision on faith and morals). Jesus promise His Church that He will send the Holy Spirit to teach and remind the of all truth (key word, all) (Jn 14: 16-17; 25-26; 16: 13). Before Jesus talked to the apostles, He gave Peter the authority to bind and lose in Mt 16: 16-19. Jesus also told Peter that the gates of hell will not prevail. If Peter has the authority to bind and lose and the gate of hell will not prevail against the Church, that means God must be guiding Peter and his successors to make the right decision on faith and morals.
1 Tim 3: 15 shows the infallibility of the Church. The Church upholds and defends the truth from false teachings like a pillar and foundation prevents a building from collapsing. If the Church on earth protects the truth, then the leader (the Pope) is the main one that is doing the protection.
Another key verse is Gal 1: 18, which says that Paul went to see Peter and stayed with him for fifteen days. the Greek word for “see” (it will say confer in New American Bible) in the verse is “Historeo,” which means to gain knowledge from. Paul stayed with Peter for 15 days so he can learn and see if what he is teaching is right. He could have done the same with James (or James and Peter), but Paul went to Peter and him alone for knowledge.
One key evidence from the Fathers is St Augustine Sermon 131: 10 which states:
“What then was said of the Jews, the same altogether do we see in these men now. They have a zeal of God: I hear them record that they have a zeal of God, but not according to knowledge. What is, not according to knowledge? For being ignorant of God’s righteousness, and wishing to establish their own, they have not submitted themselves unto the righteousness of God. My Brethren, share with me in my sorrow. When ye find such as these, do not hide them; be there no such misdirected mercy in you; by all means, when you find such, hide them not. Convince the gainsayers, and those who resist, bring to us.** For already have two councils on this question been sent to the Apostolic see (Rome); and rescripts also have come from thence. The question has been brought to an issue; would that their error may sometime be brought to an issue too!** Therefore do we advise that they may take heed, we teach that they may be instructed, we pray that they may be changed. Let us turn to the Lord, etc.”
