(Bishop of Hippo Regis, 395–430) played a part by emphasising the idea of "the link from consecrator to consecrated whereby the grace of order was handed on". Writing in about AD 94, Clement of Rome states that the apostles appointed successors to continue their work where they had planted churches and for these in their turn to do the same because they foresaw the risk of discord: "Our Apostles, too, by the instruction of our Lord Jesus Christ, knew that strife would arise concerning the dignity of a bishop; and on this account, having received perfect foreknowledge, they appointed the above-mentioned as bishops and deacons: and then gave a rule of succession, in order that, when they had fallen asleep, other men, who had been approved, might succeed to their ministry." According to Anglican Eric G. Jay, the interpretation of his writing is disputed, but it is clear that he supports some sort of approved continuation of the ministry exercised by the apostles which in its turn was derived from Christ. Hegesippus (180?) and Irenaeus (180) introduce explicitly the idea of the bishop's succession in office as a guarantee of the truth of what he preached in that it could be traced back to the apostles, and they produced succession lists to back this up. That this succession depended on the fact of ordination to a vacant see and the status of those who administered the ordination is seldom commented on. Woollcombe also states that no one questioned the apostolicity of the See of Alexandria despite the fact that its Popes were consecrated by the college of presbyters up till the time of the Council of Nicaea in 325. On the contrary, other sources clearly state that Mark the Evangelist is the first bishop of Alexandria (Pope of Alexandria), then he ordained Annianus as his successor bishop (2nd Pope) as told by Eusebius. James F. Puglisi, director of Centro Pro Unione, made a conclusion about Irenaeus' writings: "the terms episkopos and presbyteros are interchangeable, but the term episkopos [bishop] is applied to the person who is established in every Church by the apostles and their successors". According to Eric G. Jay, Irenaeus also refers to a succession of presbyters who preserve the tradition "which originates from the apostles". and later goes on to speak of their having "an infallible gift of truth" [charisma veritatis certum]. Jay comments that this is
