I think this is an incorrect assumption.
Our 'pope' is Jesus and the Holy Spirit - - -
John 14:26
But the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you.
Then how do you explain the wide variety of Protestant interpretations of Scripture.
Uniting agains Catholics is no proof that any particular Protestant interpretation is more accurate.
