San Pedro Apostol, or Saint Peter the Apostle, is one of the twelve disciples of Jesus Christ and is considered a foundational figure in Christianity. He is often recognized as the first Pope of the Roman Catholic Church and is known for his role in spreading the teachings of Jesus after the crucifixion. Saint Peter is traditionally depicted holding keys, symbolizing his authority to bind and loose in heaven and on earth. His feast day is celebrated on June 29, and he is the patron saint of fishermen, net makers, and shipbuilders, reflecting his early life as a fisherman on the Sea of Galilee.
