Most scriptures are written to mean what they mean, quite simply, no spin. Others are mystery and may never be completely known until the return of Christ. The Holy Spirit is my authority. My pastor is the head of my church but he’s not perfect either. Same as the Pope or any priest. They aren’t infallible. None of us are.
Please cite the definition that Catholics use for infallibility and explain what that has to do with a person being perfect.
Do you even know what infallibility means?
