Many Protestant writers have attempted to explain away the meaning of this remarkable passage, but the candid student of history is bound to listen respectfully to its testimony. When we assign to the words of Irenaeus all the significance of which they are susceptible, they only attest the fact that, in the latter half of the second century, the Church of Rome was acknowledged as the most potent of all the apostolic Churches. And in the same place the grounds of its pre-eminence are enumerated pretty fully by the pastor of Lyons. It was the most ancient Church in the West of Europe; it was also the most populous; like a city set upon a hill, it was known to all; and it was reputed to have had for its founders the most illustrious of the inspired heralds of the cross, the apostle of the Gentiles, and the apostle of the circumcision. [567:2] It was more “potentially principal,” because it was itself the principal of the apostolic or principal Churches.
It has been already stated that every principal bishop, [567:3] or presiding minister of an apostolic Church, sent the Eucharist to the pastors around him as a pledge of their ecclesiastical fellowship; and it would appear that the bishop of Rome kept up intercourse with the other bishops of the apostolic Churches by transmitting to them the same symbol of catholicity. [567:4] The sacred elements were doubtless conveyed by confidential churchmen, who served, at the same time, as channels of communication between the great prelate and the more influential of his brethren. By this means the communion of the whole Catholic Church was constantly maintained.
