I affirm that the distinction between the word and the position is essential. Saint Irenaeus, writing
Against Heresies between 175 and 190 A.D., explicitly references the succession of bishops in Rome to defend apostolic tradition. He names Linus, Anacletus, Clement, and others as successors of Peter, establishing the continuity of episcopal authority in the See of Rome. This is not merely a linguistic reference to “pope” but a theological affirmation of Petrine succession. As Irenaeus states:
“It is within the power of all, therefore, in every Church, who may wish to know the truth, to contemplate the tradition of the apostles which has been made known throughout the whole world. And we are in a position to enumerate those who were instituted bishops by the apostles, and their successors down to our own times” (Against Heresies 3.3.1).
