That is simply not true. The Pope is bound by Scripture same as any Christian. The difference comes in the interpretation of Scripture - Catholics understand that God's teachings come in both oral and written form. Protestants tend to believe in only the latter.
If you want to cherry-pick Scripture quotes, let's look at this:
"Call no man your father on earth, for you have one Father, who is in heaven" (Matt. 23:9)
Tell me, what do you call the gentleman who provided half of your DNA?
I called him Dad - in the flesh. But God is my father, for we read, "But to all who did receive him, who believed in his name, he gave the right to become children of God..." and "but you have received the Spirit of adoption as sons, by whom we cry, "Abba! Father!" 16 The Spirit himself bears witness with our spirit that we are children of God..."
I haven't cherry-picked any Scriptures. I would appreciate it if you would cite an example otherwise.
Since the Pope alone can interpret scripture, he is free to twist it into a pretzel to get the results he wants. Consider Purgatory and Indulgences...or the ridiculous idea that Mary was born sinless and lived sinless...or the even more ridiculous idea that Peter was made Vicar of Christ by Jesus!
