Which pope was the first to use the title Vicar of Christ for the successor of St. Peter?

• A. Urban II
• B. Innocent III
• C. Gregory IX
• D. Leo X

Answer: (B)

Vicar of Christ is a title that expresses the pope as Christ’s representative on earth, carrying the highest level of spiritual authority in the church. Innocent III, ruling at the turn of the 12th to 13th centuries, is the first pope known to use this exact designation in his official acts and writings, making it a formal claim of papal primacy. By adopting this explicit title, he underscored that the pope stands in a direct line of authority from Christ, above other bishops and secular rulers. The designation continued to be used by later popes, but Innocent III set the precedent for its formal self-designation.
