What does it mean to say that the pope is infallible?

Just as Christ established a visible Church, He also provided a visible person to guide the Church—the pope. Because the pope is guiding and teaching the Church in Christ’s name, His teachings must be infallible. Christ’s profound love for the Church is manifested in the doctrine of papal infallibility, which asserts that the pope is preserved by God from error when teaching on matters of faith and morals. How does this show Christ’s love for us? He didn’t want to leave His Church in darkness. He wanted His doctrines to be consistent so His people could be guided by truth. The core of papal infallibility is faithfulness to Christ. All of the Catholic Church’s teachings are Christocentric—they point toward Christ, who is at the center of her teachings. That is why the Catholic Church doesn’t change her doctrines to adjust to the changes in society and culture. The pope helps to uphold and preserve the teachings of Christ. Jesus Himself promised us, “I am with you always, to the close of the age” (Matthew 28:20). To make true His promise, Christ gifted the Church with an unbroken line of popes for 2,000 years, teaching with the papal infallibility that Christ bestowed on their office.
