Hi, Trento. Could you tell me when Apostile Peter went to Rome, when he became Bishop of Rome?
According to the witness of our ancient Christian forefathers:
(1) Tertullian (c. AD 197) speaks of Peter apart from Paul as ordaining Clement as his episcopal successor (De Praescrip Haer 32).
(2) The Poem Against Marcion (c. 200 AD) states how "Peter bad Linus to take his place and sit on the chair whereon he himself had sat" (III, 80). The word "chair" (cathedra) in ecclesiastical language always means one's episcopal throne (i.e. the bishop's chair).
(3) Caius of Rome (214 AD) calls Pope Victor the thirteenth bishop of Rome after Peter (Euseb HE V, 28).
(4) Hippolytus (225 AD) counts Peter as the first Bishop of Rome (Dict Christian Biog I, 577).
(5) Cyprian (in 250) speaks of Rome as "the place of Peter" (Ep ad Anton), and as "the Chair of Peter" (Ep ad Pope Cornelius).
(6) Firmilian (257) speaks of Pope Stephen's claim to the "succession of Peter" and to the "Chair of Peter" (Ep ad Cyprian).
(7) Eusebius (314) says that Peter was "the bishop of Rome for twenty-five years" (Chron an 44), and calls Linus "first after Peter to obtain the episcopate" (Chron an 66). He also says that Victor was "the thirteenth bishop of Rome after Peter" (HE III, 4).
(8) The Council of Sardica "honors the memory of the Apostle Peter" in granting Pope Julius I the right to judge cases involving other episcopal sees under imperial Roman law (Sardica Canon IV, and Ep ad Pope Julius).
(9) Athanasius (340's) calls Rome the "Apostolic Throne" -- a reference to the Apostle Peter as the first bishop to occupy that throne (Hist Arian ad Monarch 35).
(10) Optatus (370) says that the episcopal chair of Rome was first established by Peter, "in which chair sat Peter himself." He also says how "Peter first filled the pre-eminent chair," which "is the first of the marks of the Church." (Schism Donat II, 2 and II, 3).
(11) Pope Damasus (370) speaks of the "Apostolic chair" in which "the holy Apostle sitting, taught his successors how to guide the helm of the Church" (Ep ix ad Synod, Orient ap Theodoret V, 10). Damasus also states how "The first See is that of Peter the Apostle, that of the Roman church" and says how Rome received primacy not by the conciliar decisions of the other churches, but from the evangelic voice of the Lord, when He says, "Thou art Peter..." (Decree of Damasus 382).
(12) Ambrose (c. 390) speaks of Rome as "Peter's chair" and the Roman church where "Peter, first of the Apostles, first sat" (De Poenit I, 7-32, Exp Symb ad Initiand).
(13) Jerome (c. 390) speaks of Rome as the "chair of Peter" and the "Apostolic chair," and states that Peter held the episcopal chair for twenty-five years at Rome (Epistle 15 and se Vir Illust I, 1).
(14) Augustine (c. 400) tells us to number the bishops of Rome from the chair of Peter itself (in Ps contra Part Donat), and speaks of "the chair of the Roman church in which Peter first sat" (Contra Lit Petil).
(15) Prudentius (405) writes how in Rome there were "the two princes of the Apostles, one the Apostle of the Gentiles, the other holding the First Chair" (Hymn II in honor of St Laurent, V).
(16) Bachiarius (420) speaks of Rome as "the chair of Peter, the seat of faith" (De Fide 2).
(17) Prosper of Aquitaine (429) calls Rome "the Apostolic See" and the "Chair of the Apostle Peter" (Carm de Ingratis).
(18) The Roman legates at the Council of Ephesus (431) declare how "it is a matter doubtful to none that Peter lived and exercised judgement in his successors" and how "the holy and most blessed [Pope] Celestine, according to due order, is his successor and holds his place" (Acta Councilia, session 3, tom III, col 621).
(19) Peter Chrysologus (440) speaks of "blessed Peter living and presiding in his own see" (Ep ad Eutech).
(20) Pope Leo the Great (440) says how "the whole Church acknowledges Peter in the See of Peter (Rome)" (Serm II, 2).
(21) At the Council of Chalcedon (451), the assembled bishops respond to the teaching of Pope Leo the Great by crying out, "Peter has spoken through Leo." The sentence of the council is pronounced by the legates "in the name of Leo, the Council, and St. Peter" (Canons of Chalcedon).
(22) The Synodical Letter to Pope Leo from Chalcedon calls the Pope "the interpreter of Peter's voice."
(23) Emperors Theodosius and Valentinian III (450) speak of "the primacy of the Apostolic See (Rome), made firm on account of the merits of Peter,
Chief of the Corona of Bishops" (Inter ep Leon I, Vol XI, col 637).
