What about good Popes like Benedict XVI?
***
Are you telling me that for salvation I have to submit to the authority of one non-Scriptural office, which has historically been held by, and is currently also being held by some very, very evil men?
That is exactly what Roman Catholicism teaches.
"Furthermore, we declare, we proclaim, we define that it is absolutely necessary for salvation that every human creature be subject to the Roman Pontiff."

The wide ranging scope of this proclamation has been diminished or minimized by Roman Catholics. Unam teaches that every person, including presidents, governors, rulers, etc, are to be subject to the pope. Think about the implications of that statement.
When Unam is brought forward to Roman Catholics in light of the on-going debate over their current pope, RCs dismiss Unam Sanctam....yet, they maintain that Christians have to be a member of the RCC and follow the pope.
Roman Catholics don't practice what they preach....for if they did there wouldn't be the incessant posting of articles against the current pope.
Too bad the internet wasn't around for Luther!
