In Acts St. Peter appears as the leader of the Church. At the election of Matthias in place of Judas, at the descent of the Holy Ghost at Pentecost, at the admission of the Gentiles in the person of Cornelius and his family to the privileges of the new covenant, at the emancipation of the Gentile Christians from the Jewish ceremonial law at the Council of Jerusalem, St. Peter is foremost (Acts i. 15-26; ii. 1-42; x.; xv. 6-11). Soon after the Council St. Peter was at Antioch, and weakly "dissembled" by disguising his belief in the truth that the Gentile Christians were on the same spiritual level as the Jewish Christians. He was rebuked by St. Paul (Gal. ii. 11-14). He does not seem to have laboured in Rome until near the end of his life. The Roman tradition that he was bishop of that city for twenty-five years is almost certainly a legend, based on the fact that twenty-five years elapsed between the year when the apostles were believed to have temporarily left Jerusalem (twelve years after the Crucifixion) and the date of his martyrdom. There is, however, no ground for disputing the fact that {237} he died at Rome during the Neronian persecution. There are several reasons for thinking that he survived St. Paul for a short period, though St. Augustine asserts that he was martyred before St. Paul. He was crucified near the middle of the circus of Nero, on a spot afterwards marked by a "chapel of the crucifixion." He was buried nigh at hand. His tomb, probably in the form of a _cella_ or open apse, is mentioned by Caius of Rome about A.D. 200. A huge basilica was built over it by the Emperor Constantine, and remained until it was replaced in the 16th century by the present St. Peter's. In spite of his unique position, St. Peter in 1 Pet. v. 1 speaks of himself as a "presbyter," as St. John does in 2 John 1 and 3 John 1 (compare also 1 Tim. iv. 14, where St. Paul reckons himself as a member of the "presbytery"). At this period, and for many years later, the word "presbyter" was vague enough to be applied to the highest officers of the Church.
