Catholics are Christians that believe in a divinely inspired and error-free Bible, the confession of sins to a priest, praying the Rosary, and that on matters of religion, the Pope is infallible. Catholics also believe in the intersession of saints, the veneration of Mary and that Jesus is present in the Eucharist.
Catholics have many beliefs that set them apart from Protestant Christians. The belief that the pope, when he speaks on theological matters, is infallible, is one such belief. The doctrine of infallibility states that the Holy Spirit guides the church and keeps it free from error. However when the Pope speaks on other matters, such as politics, he is not considered infallible. Catholics are required to believe only those things he states that are infallible.
Mary is venerated, or held to high esteem, within the Catholic church because of her willingness to be the mother of Jesus. Catholics believe that she was born without the stain of original sin, called the immaculate conception.
Perhaps the most important belief for Catholics is the presence of Jesus in the Eucharist. Catholics believe that the communion wafer and wine become the actual body and blood of Christ. This process, known as transubstantiation, is the focal point of all Catholic worship services.
