I am still wondering why God would attribute such high responsibility and honors to a man who would end up in hell for eternity. This does not sound like an understandable spiritual end for the visible leader of the flock of whom the following has been said said:
Catechism of St. Pius X
50 Q: Who is the Pope?
A: The Pope, who is also called the Sovereign Pontiff, or the Roman Pontiff, is the Successor of St. Peter in the See of Rome, the Vicar of Jesus Christ on earth, and the visible Head of the Church.
52 Q: Why is the Roman Pontiff the Vicar of Jesus Christ?
A: The Roman Pontiff is the Vicar of Jesus Christ because He represents Him on earth and acts in His stead in the government of the Church.
53 Q: Why is the Roman Pontiff the Visible Head of the Church?
A: The Roman Pontiff is the Visible Head of the Church because he visibly governs her with the authority of Jesus Christ Himself, who is her invisible Head.
54 Q: What, then, is the dignity of the Pope?
A: The dignity of the Pope is the greatest of all dignities on earth, and gives him supreme and immediate power over all and each of the Pastors and of the faithful.
55 Q: Can the Pope err when teaching the Church?
A: The Pope cannot err, that is, he is infallible, in definitions regarding faith and morals.
58 Q: What sin would a man commit who should refuse to accept the solemn definitions of the Pope?
A: He who refuses to accept the solemn definitions of the Pope, or who even doubts them, sins against faith; and should he remain obstinate in this unbelief, he would no longer be a Catholic, but a heretic.
62 Q: How should every Catholic act towards the Pope?
A: Every Catholic must acknowledge the Pope as Father, Pastor, and Universal Teacher, and be united with him in mind and heart.
Catechism of Trent
"Above all these, the Catholic Church has always placed the Supreme Pontiff of Rome, whom Cyril of Alexandria, in the Council of Ephesus, named the Chief Bishop, Father and Patriarch of the whole world. He sits in that chair of Peter in which beyond every shadow of doubt the Prince of the Apostles sat to the end of his days, and hence it is that in him the Church recognises the highest degree of dignity, and a universality of jurisdiction derived, not from the decrees of men or Councils, but from God Himself. Wherefore he is the Father and guide of all the faithful, of all the Bishops, and of all the prelates, no matter how high their power and office; and as successor of St. Peter, as true and lawful Vicar of Christ our Lord, he governs the universal Church."
If I were a Catholic I would feel a bit discouraged that Popes, with all their "graces" and honors, may not make it to heaven. I would have to have a great deal of confidence in myself to "merit to enter with him into the marriage feast and be numbered among the blessed" when some Vicars of Christ have failed.
