How many successors of the original 13 apostles are there in the RCC?
Judas is cut out. There are only 12 Gates to the Kingdom.
Only from the Apostles comes the Apostolic lineage.
It would be very tedious to reckon all the successions of Bishops, even by Irenaeus’ time, so he points out the successions of Bishops of the Church of Rome, which was the most important Church, as it is today.
“Since, however, it would be very tedious, in such a volume as this, to reckon up the successions of all the Churches, we do put to confusion all those who, in whatever manner, whether by an evil self-pleasing, by vainglory, or by blindness and perverse opinion, assemble in unauthorized meetings; [we do this, I say,] by indicating that tradition derived from the apostles, of the very great, the very ancient, and universally known Church founded and organized at Rome by the two most glorious apostles, Peter and Paul; as also [by pointing out] the faith preached to men, which comes down to our time by means of the successions of the bishops. For it is a matter of necessity that every Church should agree with this Church, on account of its pre- eminent authority, that is, the faithful everywhere, inasmuch as the apostolical tradition has been preserved continuously by those [faithful men] who exist everywhere.” Irenaeus, Against Heresies, 3:3:2 (A.D. 180).
“It is my purpose to write an account of the successions of the holy apostles, as well as of the times which have elapsed from the days of our Saviour to our own; and to relate the many important events which are said to have occurred in the history of the Church; and to mention those who have governed and presided over the Church in the most prominent parishes, and those who in each generation have proclaimed the divine word either orally or in writing… When Nero was in the eighth year of his reign, Annianus succeeded Mark the evangelist in the administration of the parish of Alexandria…Linus …was Peter’s successor in the episcopate of the church there…Clement also, who was appointed third bishop of the church at Rome.” Eusebius, Ecclesiastical History,1:1,2:24, (A.D. 325).
“[W]e shall not recede from the faith … as once laid it continues even to this say, through the tradition of the fathers, according to the succession from the apostles, even to the discussion had at Nicea against the heresy which had, at that period, sprung up.” Hilary of Poitiers, History Fragment 7 (ante A.D. 367).
“[D]uring the days of that Anicetus, bishop of Rome, who succeeded Pius and his predecessors, For, in Rome, Peter and Paul were the first both apostles and bishops; then came Linus, then Cletus … However the succession of the bishops in Rome was in the following order. Peter and Paul, and Cletus, Clement…” Epiphanius, Panarion, 27:6 (A.D. 377).
Bishop Athanasius was a Successor from Mark.
“He [St. Athanasius] is led up to the throne of Saint Mark, to succeed him in piety, no less than in office; in the latter indeed at a great distance from him, in the former, which is the genuine right of succession, following him closely. For unity in doctrine deserves unity in office; and a rival teacher sets up a rival throne; the one is a successor in reality, the other but in name. For it is not the intruder, but he whose rights are intruded upon, who is the successor, not the lawbreaker, but the lawfully appointed, not the man of contrary opinions, but the man of the same faith; if this is not what we mean by successor, he succeeds in the same sense as disease to health, darkness to light, storm to calm, and frenzy to sound sense.” Gregory of Nazianzen, Oration 21:8 (A.D. 380).
“For they [Novatians] have not the succession of Peter, who hold not the Chair of Peter, which they rend by wicked schism; and this, too, they do, wickedly denying that sins can be forgiven even in the Church, whereas it was said to Peter: ‘I will give unto thee the keys of the kingdom of heaven. and whatsoever thou shalt bind on earth shall be bound also in heaven, and whatsoever thou shall loose on earth shall be loosed also in heaven.'” Ambrose, Concerning Repentance, 7:33 (A.D. 384).
“It has been ordained by the apostles and their successors, that nothing be read in the Catholic Church, except the law, and the prophets, and the Gospels.” Philastrius of Brescia, On Heresies (ante A.D. 387).
“‘To the fellow-Bishops and Deacons.” What is this? Were there several Bishops of one city? Certainly not; but he called the Presbyters so. For then they still interchanged the titles, and the Bishop was called a Deacon. For this cause in writing to Timothy, he said, “Fulfill thy ministry,’ when he was a Bishop. For that he was a Bishop appears by his saying to him, ‘Lay hands hastily on no man.’ (1 Tim. v. 22.) And again, ‘Which was given thee with the laying on of the hands of the Presbytery.’ (1 Tim. iv. 14.) Yet Presbyters would not have laid hands on a Bishop. And again, in writing to Titus, he says, ‘For this cause I left thee in Crete, that thou shouldest appoint elders in every city, as I gave thee charge. If any man is blameless, the husband of one wife’ (Tit. i. 5, 6); which he says of the Bishop. And after saying this, he adds immediately, ‘For the Bishop must be blameless, as God’s steward, not self willed:’ (Tit. i. 7.)” John Chrysostom, Homilies on Phillipians, 1:1 (A.D. 404).
