Saint Peter is considered the first Pope. Peter had humble beginnings and became one of the Twelve Apostles of Jesus. In the time following Christ's Ascension, Peter stood as the unquestionable head of the Apostles, which the book of Acts clearly describes. He went on to appoint the replacement of Judas Iscariot, spoke first to the crowds that had assembled after the descent of the Holy Spirit at Pentecost, he was the first Apostle to perform miracles in the name of the Lord, and he rendered judgment upon the deceitful Ananias and Sapphira, both of whom were stealing from church members and God alike. According to rich tradition, Peter was crucified on the Vatican Hill upside down because he declared himself unworthy to die in the same manner as the Lord. His symbols include an inverted cross, a boat, and the cock.
