In a third passage Eusebius,[58] after speaking of Ignatius “as the second who received the episcopal succession of St. Peter at Antioch,” Evodius having been the first, and after quoting at length his letters, proceeds, “There were many others also noted in the times of these men who held the first rank of the apostolic succession. These, as the holy disciples of such men, built up further in every place the foundations of the Churches which had been laid by the Apostles. They spread the preaching further abroad and scattered the saving seeds of the kingdom of heaven far and wide through the breadth of the world. For the most of the disciples at that time, kindled by a more ardent love of the divine word, had first fulfilled the Saviour’s exhortation by distributing their substance to the needy. Afterwards, leaving their country, they performed the work of evangelists, filled with a noble ambition to proclaim Christ to such as had not yet heard the word of faith, and to deliver to them the writing of the sacred Gospels. Thus laying merely the foundations of the faith in new and strange places, and, appointing others to the pastoral office, they left them to cultivate the new plantation, and again went on to other places and nations by God’s grace and co-operation. For a great number of marvellous works of power were still done by them through the Holy Spirit; so that at the first hearing multitudes of men in a mass received into their souls readily the worship of the One Creator. As I cannot record by name all those who received the first succession of the Apostles as pastors and evangelists in the Churches throughout the world, I will mention those only where tradition of apostolical doctrine is carried down to us by actual memorials.”

The gradations thus marked in the propagation of the gospel are three: first, that of the Apostles in Judea before their dispersion; secondly, that of the Apostles with their personal fellow-workers throughout the world; thirdly, that of the men called Apostolic, because they had lived in the time of the Apostles without having been their first co-operators, or, to use the Pauline expression, fellow-soldiers. This carries us over the ninety years from the Day of Pentecost to the end of Trajan’s reign, during which reign, the time, as Eusebius calls it, of St. Clement of Rome and of St. Ignatius of Antioch, he notes that there was a specially abundant outburst of such teachers.

Eusebius bears witness through the whole of his History to the universality of the episcopal regimen. Likewise he carefully gives the descent of the three great Sees of Rome, Alexandria, and Antioch. He notes how they took their rise from the person of Peter, who sat at Antioch himself, who sent his son Mark to Alexandria, and whose coming to Rome the historian describes in the words following:—

“Immediately in the reign of the Emperor Claudius, the most benign and man-loving providence of God conducted to Rome Peter, the great and powerful among the Apostles, who for his virtue was chosen to lead them all against Simon, the plague of mankind.[59] Peter, like a valiant commander of God’s army, clothed in heavenly panoply, carried from the East to the West the precious freight of intellectual light, bearing the proclamation of the heavenly kingdom, to be the sure and saving word of souls.” He records the martyrdom of the two Apostles, Peter and Paul, together at Rome under Nero, giving for this fact a fourfold testimony; of historians generally; of their tombs, which were still to be seen at Rome; of the presbyter Cains, who, at the beginning of the third century, appealed to the existence of these tombs, the one at the Vatican, the other on the Ostian Road, as a proof where “the sacred tabernacles of these Apostles had been deposited;” and lastly, to the letter of Dionysius, Bishop of Corinth in the middle of the second century, who spoke of their having both taught the Church of Corinth as well as that of Rome, and of both having suffered martyrdom together. “These particulars I have given,” says Eusebius, “that the memory of the fact may be the more confirmed.”[60] He gives carefully during two hundred years the descent of the bishops in these three Sees, and the number of years they sat—a tacit witness to the eminent rank of the three great Mother Sees established by Peter in the three chief cities of the Roman Empire; and an honour which he gives besides only to the Church of Jerusalem, since all, he says, have ever borne reverence “to the throne of the Apostle James, the first who received the episcopate of the city of Jerusalem from the Saviour Himself and the Apostles!”

In another place he writes: “Again, when I consider the power of the Word, how the most populous churches were constructed by the rudest and most ignoble disciples of Jesus, not in obscure and unknown places, but founded in the most conspicuous cities, in very imperial Rome itself, in Alexandria and Antioch, for all Egypt and Libya, for Europe, and for Asia,—again I am compelled to search out the reason of this, and to confess that they could not have succeeded in so audacious an attempt except by some divine and superhuman power, and the working together with them of Him who said ‘Make disciples all nations in My name.’”[61]

Between St. Clement of Rome and St. Ignatius of Antioch at the end of the first century, and Eusebius at the beginning of the fourth, stands at the end of the second century the witness of Tertullian. In setting forth the legal ground of prescription against the heretics of his day, he gives an account of the original propagation of the divine kingdom, which exactly tallies with all that precedes. “Christ Jesus our Lord ... had chosen twelve disciples to be attached to His side, whom He destined to be the teachers of the nations. Accordingly, after one of these had been struck off, He commanded the eleven others, on His departure to the Father, to go and teach all nations, who were to be baptized into the Father, and into the Son, and into the Holy Ghost. Immediately, therefore, the Apostles, whom this designation indicates as the Sent, having on the authority of a prophecy, which occurs in a psalm of David, chosen Matthias by lot as the twelfth into the place of Judas, obtained the promised power of the Holy Ghost for the gift of miracles and of utterance. And after first bearing witness to the faith in Jesus Christ throughout Judea, and founding Churches, they next went forth into the world, and preached the same doctrine of the same faith to the nations. They then, in like manner, founded Churches in every city” (that is, an episcopal See in each city, without which, as St. Ignatius told us, there is no Church) “from which all the other Churches, one after another, derived the tradition of the faith and the seeds of doctrine, and are every day deriving them that they may become Churches. Indeed it is on this account only that they are able to deem themselves apostolic, as being the offspring of Apostolic Churches. Every sort of thing must necessarily revert to its original for its classification. Therefore the Churches, though they are so many and so great, comprise but the one Primitive Church founded by the Apostles, from which they all spring. In this way all are primitive and all are apostolic, while all together make up a unity; while they have peaceful communion, and title of brotherhood, and bond of hospitality, privileges which no other rule directs than the one tradition of the self-same mystery. From this, then, do we prescribe the rule that, since the Lord Jesus Christ sent the Apostles to preach, no other ought to be received as preachers than those whom Christ appointed; for ‘no man knoweth the Father save the Son, and he to whomsoever the Son will reveal Him.’ Nor does the Son seem to have revealed Him to any other than the Apostles, whom He sent forth to preach that, of course, which He revealed to them. Now what this was which they preached—in other words, what it was which Christ revealed to them—can, as I must here likewise prescribe, properly be proved in no other way than by those very Churches which the Apostles founded in person, by declaring the gospel to them directly themselves, both by word of mouth, as the phrase is, and subsequently by their Epistles. If, then, these things are so, it is in the same decree manifest that all doctrine which agrees with the Apostolic Churches—those wombs and original sources of the faith—must be reckoned for truth, as undoubtedly containing that which the said Churches received from the Apostles, the Apostles from Christ, and Christ from God; whereas all doctrine must be prejudged as false which savours of contrariety to the truth of the Churches and Apostles of Christ and God.”[62]

But the whole work of St. Irenæus against heresies is based exactly upon the fact which we are here setting forth. His object was to show that the true faith was preserved intact in all the Churches of the world by means of the bishops appointed by the Apostles. Thus he commences his third book: “For the Lord of all gave to His Apostles the power of the gospel, through whom we have learnt the truth, that is, the doctrine of the Son of God; to whom the Lord said, ‘He who heareth you, heareth Me, and who despiseth you, despiseth Me, and Him who sent Me.’” ... “For after our Lord arose from the dead, and they had been clothed with the power of the Holy Spirit coming down upon them from on high, they were completely filled and had perfect knowledge: they went forth into the ends of the world, proclaiming the gospel of good things from God, and announcing peace from heaven to men, all of them and every one of them possessing equally the gospel of God.” ... “All, therefore, who wish to see the truth may behold in every Church the tradition of the Apostles, which was made known through the whole world; and we can number up those who were appointed by the Apostles bishops in the Churches, and their successors down to our own times, who have neither taught nor known any such delirious imagination as theirs.” He is speaking of the heresy of Valentinus. “For had the Apostles known recondite mysteries, which they were in the habit of teaching separately and secretly from the rest to the perfect, they would deliver such especially to those to whom they were intrusting the Churches themselves. For they desired those to be very perfect and blameless in all things whom they were leaving as their successors, handing over to them their own place of teaching. For if these acted faultlessly, the good would be great; whereas if they failed, the calamity would be complete.”

Irenæus sums up all this view in another place, where he says: “True knowledge is the doctrine of the Apostles, and the ancient compacted fabric of the Church through the whole world, and the character of the Body of Christ, according to the succession of bishops, to whom they delivered that Church which is everywhere.”[63]

In what has preceded we have traced carefully the transmission of spiritual authority, putting together the various intimations respecting it which are given in the four Gospels, the Acts, the Epistles of St. Paul, and the Apocalypse. From these intimations a most clear and unambiguous result has been deduced. Then proceeding to historical proofs, we find the third Pope from St. Peter, at the end of the first century, in an official document, summing up in words of great precision what had been the actual course of things in the two generations which lay between the Day of Pentecost and the time at which he was writing. If we compare the Gospels which record the institution of the power, and the history which records its actual beginning and exercise, as thus given by St. Clement, we find the most exact agreement. Another saint and martyr, contemporary with St. Clement, and holding by second succession from St. Peter what became the great patriarchal See of the East, affords the strongest corroboration to him in the doctrinal statements which are found interwoven in the letters addressed by him to various churches as he is carried a prisoner on his way to martyrdom. The first extant historian, writing in 324, on the eve of the assembling of the first General Council, testifies throughout the ten books of his work the universality of the episcopal regimen, and intimates its organic structure by giving each link in the spiritual descent of the three great Sees of Peter and of the Church of Jerusalem. Intermediate between these three authorities, Irenæus, Bishop of Lyons, writing seventy years after St. Clement, and Tertullian, writing thirty years after Irenæus, give very graphic accounts of the Church in their day, which exactly accord both with the Pope and Martyr-bishop preceding and the historian following them. Instead of calling in other witnesses, let us attempt to give a general view of the Episcopate as it is found when emerging from the last great persecution, which terminated the first stadium of its course, and was followed by the peace of the Church, proclaimed by the Emperor Constantine 283 years after the Day of Pentecost. The whole of this period marks a time in which the growth of the Church and the form of her constitution were the result of a power proceeding solely from within, never favoured by the civil power, often actively persecuted, and daily in a thousand ways discouraged.

St. Augustine, writing in the year 398, observes precisely of this time, that is, the year 314, that if the Donatists suspected the judgment of their African colleagues, there were thousands of bishops beyond the sea to whom they might have recourse.[64] In his own time he counted 476 Catholic bishoprics in the African provinces. Throughout the Roman Empire it would seem that, before the peace of the Church, not only every considerable city, but even small towns, possessed their bishop. St. Hilary says: “Though there be only one Church in the world, yet every city has its own Church;” and St. Cyprian and St. Dionysius of Alexandria assert this of their own time.[65]
