A major stumbling block to reconciliation with Protestant groups is the Roman Catholic Church's

• A. Purgatory
• B. Papal infallibility
• C. Transubstantiation
• D. Immaculate Conception

Answer: (B)

The key issue tested is how authority and interpretation of doctrine differ between Catholicism and Protestant groups. The doctrine of papal infallibility holds that the pope is preserved from error when he speaks ex cathedra on faith and morals for the whole Church. Defined in the 19th century (Vatican I), it gives the pope a uniquely authoritative, universal role in teaching the Church. Protestants generally reject the idea of a single human figure with infallible authority over all Christians. They emphasize Scripture as the ultimate authority (often summarized as sola scriptura) and resist the notion that the pope can bind all believers in infallible declarations. Because accepting papal infallibility would entail a major shift in how church authority is distributed, it stands as a major obstacle to reconciliation between the groups—the willingness to subordinate or relocate authoritative power in the Church. Purgatory, transubstantiation, and the Immaculate Conception are significant Catholic doctrines, but they do not address the central issue of how binding authority is exercised and who holds ultimate interpretive power. That is why papal infallibility is the best answer to why reconciliation has been so challenging.
