i think what he is saying is that the concept of papal infalliblity is not in Scripture. I think even catholics would agree that Peter was not looked upon as being infallible. God did use him mightly but even that does not translate into infallibly for him or later popes.
I think you don’t understand the doctrine of infallibity. It is not the same as impeccability. All the Apostles taught infallibly. It is the Teaching that is infallible, not the person. Jesus promised to lead the Apostles into “all truth”.
Here is what the same St. John Chrysostom has to say about Saint John the Evangelist:
“For the son of thunder, the beloved of Christ, the pillar of the Churches throughout the world, who holds the keys of heaven, who drank the cup of Christ, and was baptized with His baptism, who lay upon his Master’s bosom with much confidence, this man comes forward to us now…. By this Apostle stand the powers from above, marveling at the beauty of his soul, and his understanding, and the bloom of that virtue by which he drew unto him Christ Himself, and obtained the grace of the Spirit. For he hath made ready his soul, as some well-fashioned and jeweled lyre with strings of gold, and yielded it for the utterance of something great and sublime to the Spirit” (St. John Chrysostom, First Homily on the Gospel of St. John).
“Were John about to converse with us, and to say to us words of his own, we needs must describe his family, his country, and his education. But since it is not he, but God by him, that speaks to mankind, it seems to me superfluous and distracting to enquire into these matters. And yet even thus it is not superfluous, but even very necessary. For when you have learned who he was, and from whence, who his parents, and what his character, and then hear his voice and all his heavenly wisdom, then you shall know right well that these (doctrines) belong not to him, but to the Divine power stirring his soul…. Not so this fisherman;
for all he saith is infallible; and standing as it were upon a rock, he never shifts his ground. For since he has been thought worthy to be in the most secret places, and has the Lord of all speaking within him, he is subject to nothing that is human” (St. John Chrysostom, Second Homily on the Gospel of St. John). ]
It is the Teaching that is held to be without error, not the individual. We can clearly see in scripture that Peter was not “perfect” always in action.
Where is the “chair of Moses” used in the writings of the apostles (NT) as a basis for infalliblity?
Jesus commands the people to “practice and observe whatever they tell you” BECAUSE they sit on Moses’ seat. Why would He command people to walk in error? Would you not agree that all the commandments of Jesus are infallible?
Matt 23:1-4
2 "The scribes and the Pharisees sit on Moses’ seat; 3 so practice and observe whatever they tell you, but not what they do; for they preach, but do not practice.
If you look at Paul’s description of church structure in Ephesians and I Timothy for example he never appeals to a chair of Moses or of Peter.
Paul appeals to the foundation of the Apostles and prophets, upon whom the Church is built. If you believe that Paul is not in unity with Peter and the other Apostles you have been misled.
Code:
It is one thing to have an authority in the church (protestants would agree with this) but it is another to claim this authority is also infallible.
What good is an authority that errs? Jesus promised that He would not leave the Apostles “orphaned”. That means that He meant what He said when He promised to be with them until the end of the Age.
