Good question Joe. I guess a follow question by parity of reason would be “How can one Pope say to another Pope that his interpretation of scripture is wrong?” example: Pope Honorius I. No one here wants to downplay the importance of tradition, but we understand tradition to be subservient to Scripture. This is why Peter can say that Scripture is “more sure” than his own experience of hearing the words “This is my Son” spoken by God himself on the Mount of Transfiguration. Also Paul rebuked the “first Pope” for straying from the proper understanding of circumcision, why? Not becasue Paul was ordering the proper tradition to follow. For neither circumcision nor uncircumcision count for anything. Instead Paul appealed to the “truth of the gospel” over against the actions of Peter. I hope that begins to help you with trying to understand our stance on your question.
