How come your Church is fallible? Have they not ever been wrong? Example: the Inquistition
Thanks, I think I understand your question now. The Church has definitely been wrong in the past and will be wrong in the future on some things. Examples: aspects of the Inquisitions, Priest abuse scandal, selling indulgences, etc. Those things do not fall under Papal Infallibility.
Infallibility does not mean a pope is incapable of sin. Infallibility does not mean that the pope is inspired. Infallibility cannot be used to change existing doctrines or proclaim new ones. Infallibility does not mean that a pope cannot err when he speaks as a private teacher. Infallibility is not something that endows a pope with divine powers, but rather it is a gift of the Holy Spirit that protects the Church from the human frailties of a pope.
When Jesus told Peter “whatever you bind or loose on earth is bound or loosed in heaven” (Matt. 16:18-19), He was promising to protect Peter from teaching error to the universal Church. Otherwise, Jesus could not make such a sweeping promise to Peter. Because God cannot lie (Titus 1:2; Heb. 6:18), Peter must be protected from teaching error, since what he binds or looses, heaven binds and looses as well. Indeed, God intrudes into the mind of the pope and prevents him from teaching error, just like the Father penetrated the mind of Peter when he confessed that Jesus was the Christ.
Jesus said Peter is the rock upon which He would build the Church and gave Peter the keys to the kingdom of heaven. The basis for infallibility is the ability of the pope to accept and confess God’s divine guidance without error. It has nothing to do with the pope’s private opinions or conduct. The fact that all the popes have spoken with one voice over the past 2,000 years when it comes to dogmatizing principles of Catholic faith and morals proves that Jesus has kept His promise.
Note also that nothing the Church teaches on faith or morals just “pops up.” This is because the Church’s teaching comes from the Tradition of the apostles, which we call the sacred deposit of faith. The Church may try to clarifying the way she expresses doctrine, but there can be nothing new under the sun, as they say. Often, the Church will issue a dogmatic teaching to clarify a point of contention or refute a heresy. But clarifying the way in which she expresses the divine deposit of faith does not mean she makes up new doctrines. The doctrines remain the same.
“The Roman Pontiff, head of the college of bishops, enjoys this infallibility in virtue of his office, when, as supreme pastor and teacher of all the faithful - who confirms his brethren in the faith he proclaims by a definitive act a doctrine pertaining to faith or morals… The infallibility promised to the Church is also present in the body of bishops when, together with Peter’s successor, they exercise the supreme Magisterium,” above all in an Ecumenical Council. When the Church through its supreme Magisterium proposes a doctrine “for belief as being divinely revealed,” and as the teaching of Christ, the definitions “must be adhered to with the obedience of faith.” This infallibility extends as far as the deposit of divine Revelation itself. – CCC #891
I sincerely hope that helps you understand what we as Catholics believe.
