The Church is One

The ICCEC claims, by virtue of the apostolic succession upon which it established itself as an autocephalous patriarchate, that it is in full and licit communion with the one, holy, catholic, and apostolic Church as delineated by the “undivided Catholic Church during the first millennium of its existence”.

However, do we find, in the early Church, the view that the one Church is composed of several, separate, autocephalous patriarchates, each with doctrines differing from the other—but each and all in full and licit communion with the one, holy, catholic, and apostolic Church? If so, I am eager to see a case made for it from the Fathers. The Church I find delineated by the Fathers is a Church that is one, holy, catholic, and apostolic because her founder, Jesus Christ, imbued her permanently with these qualities, which, therefore, cannot be overturned by the sinfulness of capriciousness of man. The gates of hell shall not prevail. And hence the oneness of the Church today is the same as it was on the day of its founding at Pentecost. And the oneness of which the Fathers speak is not the so-called “oneness” purported to exist in a church composed of autocephalous patriarchates; I find the Fathers describing a Church that is permanently one in both government and doctrine.

As I have already observed, the Church, having received this preaching and this faith, although scattered throughout the whole world, yet, as if occupying but one house, carefully preserves it. She also believes these points [of doctrine] just as if she had but one soul, and one and the same heart, and she proclaims them, and teaches them, and hands them down, with perfect harmony, as if she possessed only one mouth... For the Churches which have been planted in Germany do not believe or hand down anything different, nor do those in Spain, nor those in Gaul, nor those in the East, nor those in Egypt, nor those in Libya, nor those which have been established in the central regions of the world. But as the sun, that creature of God, is one and the same throughout the whole world, so also the preaching of the truth shineth everywhere, and enlightens all men that are willing to come to a knowledge of the truth. Nor will any one of the rulers in the Churches, however highly gifted he may be in point of eloquence, teach doctrines different from these (for no one is greater than the Master); nor, on the other hand, will he who is deficient in power of expression inflict injury on the tradition. For the faith being ever one and the same, neither does one who is able at great length to discourse regarding it, make any addition to it, nor does one, who can say but little diminish it.
—St. Irenaeus of Lyons, Adversus Haereses, 1:10 (A.D. 180)

Now all these [heretics] are of much later date than the bishops to whom the apostles committed the Churches; which fact I have in the third book taken all pains to demonstrate. It follows, then, as a matter of course, that these heretics aforementioned, since they are blind to the truth, and deviate from the [right] way, will walk in various roads; and therefore the footsteps of their doctrine are scattered here and there without agreement or connection. But the path of those belonging to the Church circumscribes the whole world, as possessing the sure tradition from the apostles, and gives unto us to see that the faith of all is one and the same ... And undoubtedly the preaching of the Church is true and steadfast, in which one and the same way of salvation is shown throughout the whole world. For to her is entrusted the light of God; and therefore the “wisdom” of God, by means of which she saves all men, “is declared in [its] going forth; it uttereth [its voice] faithfully in the streets, is preached on the tops of the walls, and speaks continually in the gates of the city.” For the Church preaches the truth everywhere, and she is the seven-branched candlestick which bears the light of Christ.
—St. Irenaeus of Lyons, Adversus Haereses, 5:20 (A.D. 180)

Christ Jesus our Lord...had chosen the twelve chief ones to be at His side, and 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, so did 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, they 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 Judaea, and rounding churches (there), they next went forth into the world and preached the same doctrine of the same faith to the nations. They then in like manner rounded churches in every city, 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 will be 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, although they are so many and so great, comprise but the one primitive church, (rounded) by the apostles, from which they all (spring). In this way all are primitive, and all are apostolic, whilst they are all proved to be one, in (unbroken) unity, by their peaceful communion, and title of brotherhood, and bond of hospitality—privileges which no other rule directs than the one tradition of the selfsame mystery.
—Tertullian, The Prescription Against Heretics, 20 (A.D. 200)

For it weighs me down and saddens me, and the intolerable grief of a smitten, almost prostrate, spirit seizes me, when I find that you there, contrary to ecclesiastical order, contrary to evangelical law, contrary to the unity of the Catholic institution, had consented that another bishop should be made. That is what is neither right nor allowable to be done; that another church should be set up; that Christ’s members should be torn asunder; that the one mind and body of the Lord’s flock should be lacerated by a divided emulation. I entreat that in you, at all events, that unlawful rending of our brotherhood may not continue; but remembering both your confession and the divine tradition, you may return to the Mother whence you have gone forth; whence you came to the glory of confession with the rejoicing of the same Mother. And think not that you are thus maintaining the Gospel of Christ when you separate yourselves from the flock of Christ, and from His peace and concord; since it is more fitting for glorious and good soldiers to sit down within their own camp, and so placed within to manage and provide for those things which are to be dealt with in common. For as our unanimity and concord ought by no means to be divided, and because we cannot forsake the Church and go outside her to come to you, we beg and entreat you with what exhortations we can, rather to return to the Church your Mother, and to our brotherhood.
—St. Cyprian of Carthage, Epistle 43 (A.D. 250)

[T]he Church, which is Catholic and one, is not cut nor divided, but is indeed connected and bound together by the cement of priests who cohere with one another.
—St. Cyprian of Carthage, Epistle 68, 8 (A.D. 254)

Now then let me finish what still remains to be said for the Article, “In one Holy Catholic Church,” on which, though one might say many things, we will speak but briefly. It is called Catholic then because it extends over all the world, from one end of the earth to the other; and because it teaches universally and completely one and all the doctrines which ought to come to men’s knowledge...
—St. Cyril of Jerusalem, Catechetical Lectures, 18:22-23 (A.D. 350)

“Paul, called to be an Apostle of Jesus Christ, through the will of God, and Sosthenes our brother, unto the Church of God which is at Corinth”... “Unto the Church of God.” Not “of this or of that man,” but of God. “Which is at Corinth.” Seest thou how at each word he puts down their swelling pride; training their thoughts in every way for heaven? He calls it, too, the Church “of God;” shewing that it ought to be united. For if it be “of God,” it is united, and it is one, not in Corinth only, but also in all the world: for the Church”s name (ecclesia: properly an assembly) is not a name of separation, but of unity and concord.
—St. John Chrysostom, Homily One on First Corinthians (A.D 392)

The ICCEC claims, on its website, to have “a high view of the Church in affirming Cyprian’s claim that, ‘he who has not the Church for his mother, has not God for his Father.’” That statement of St. Cyprian’s comes from his first treatise, On the Unity of the Church. Below are excerpts from that same document which I find to indicate that the ICCEC’s high view of the Church is irreconcilable with that of the author it quotes.

4. Does he who does not hold this unity of the Church think that he holds the faith? Does he who strives against and resists the Church trust that he is in the Church, when moreover the blessed Apostle Paul teaches the same thing, and sets forth the sacrament of unity, saying, “There is one body and one spirit, one hope of your calling, one Lord, one faith, one baptism, one God?”

5. And this unity we ought firmly to hold and assert, especially those of us that are bishops who preside in the Church, that we may also prove the episcopate itself to be one and undivided. Let no one deceive the brotherhood by a falsehood: let no one corrupt the truth of the faith by perfidious prevarication. The episcopate is one, each part of which is held by each one for the whole. The Church also is one, which is spread abroad far and wide into a multitude by an increase of fruitfulness. As there are many rays of the sun, but one light; and many branches of a tree, but one strength based in its tenacious root; and since from one spring flow many streams, although the multiplicity seems diffused in the liberality of an overflowing abundance, yet the unity is still preserved in the source.

Separate a ray of the sun from its body of light, its unity does not allow a division of light; break a branch from a tree,--when broken, it will not be able to bud; cut off the stream from its fountain, and that which is cut off dries up. Thus also the Church, shone over with the light of the Lord, sheds forth her rays over the whole world, yet it is one light which is everywhere diffused, nor is the unity of the body separated. Her fruitful abundance spreads her branches over the whole world. She broadly expands her rivers, liberally flowing, yet her head is one, her source one; and she is one mother, plentiful in the results of fruitfulness: from her womb we are born, by her milk we are nourished, by her spirit we are animated.

6. The spouse of Christ cannot be adulterous; she is uncorrupted and pure. She knows one home; she guards with chaste modesty the sanctity of one couch. She keeps us for God. She appoints the sons whom she has born for the kingdom. Whoever is separated from the Church and is joined to an adulteress, is separated from the promises of the Church; nor can he who forsakes the Church of Christ attain to the rewards of Christ. He is a stranger; he is profane; he is an enemy. He can no longer have God for his Father, who has not the Church for his mother. If any one could escape who was outside the ark of Noah, then he also may escape who shall be outside of the Church. The Lord warns, saying, “He who is not with me is against me, and he who gathereth not with me scattereth.” He who breaks the peace and the concord of Christ, does so in opposition to Christ; he who gathereth elsewhere than in the Church, scatters the Church of Christ. The Lord says, “I and the Father are one;” and again it is written of the Father, and of the Son, and of the Holy Spirit, “And these three are one.” And does any one believe that this unity which thus comes from the divine strength and coheres in celestial sacraments, can be divided in the Church, and can be separated by the parting asunder of opposing wills? He who does not hold this unity does not hold God’s law, does not hold the faith of the Father and the Son, does not hold life and salvation.

7. This sacrament of unity, this bond of a concord inseparably cohering, is set forth where in the Gospel the coat of the Lord Jesus Christ is not at all divided nor cut, but is received as an entire garment, and is possessed as an uninjured and undivided robe by those who cast lots concerning Christ’s garment, who should rather put on Christ. Holy Scripture speaks, saying, “But of the coat, because it was not sewed, but woven from the top throughout, they said one to another, Let us not rend it, but cast lots whose it shall be.” That coat bore with it an unity that came down from the top, that is, that came from heaven and the Father, which was not to be at all rent by the receiver and the possessor, but without separation we obtain a whole and substantial entireness. He cannot possess the garment of Christ who parts and divides the Church of Christ. But because Christ’s people cannot be rent, His robe, woven and united throughout, is not divided by those who possess it; undivided, united, connected, it shows the coherent concord of our people who put on Christ. By the sacrament and sign of His garment, He has declared the unity of the Church.

8. Who, then, is so wicked and faithless, who is so insane with the madness of discord, that either he should believe that the unity of God can be divided, or should dare to rend it--the garment of the Lord--the Church of Christ? He Himself in His Gospel warns us, and teaches, saying, “And there shall be one flock and one shepherd.” And does any one believe that in one place there can be either many shepherds or many flocks? The Apostle Paul, moreover, urging upon us this same unity, beseeches and exhorts, saving, “I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the same thing, and that there be no schisms among you; but that ye be joined together in the same mind and in the same judgment.” And again, he says, “Forbearing one another in love, endeavouring to keep the unity of the Spirit in the bond of peace.” Do you think that you can stand and live if you withdraw from the Church, building for yourself other homes and a different dwelling, when it is said to Rahab, in whom was prefigured the Church, “Thy father, and thy mother, and thy brethren, and all the house of thy father, thou shalt gather unto thee into thine house; and it shall come to pass, whosoever shall go abroad beyond the door of thine house, his blood shall be upon his own head?” Also, the sacrament of the passover contains nothing else in the law of the Exodus than that the lamb which is slain in the figure of Christ should be eaten in one house. God speaks, saying, “In one house shall ye eat it; ye shall not send its flesh abroad from the house.” The flesh of Christ, and the holy of the Lord, cannot be sent abroad, nor is there any other home to believers but the one Church. This home, this household of unanimity, the Holy Spirit designates and points out in the Psalms, saying, “God, who maketh men to dwell with one mind in a house.” in the house of God, in the Church of Christ, men dwell with one mind, and continue in concord and simplicity.

23. God is one, and Christ is one, and His Church is one, and the faith is one, and the people is joined into a substantial unity of body by the cement of concord. Unity cannot be severed; nor can one body be separated by a division of its structure, nor torn into pieces, with its entrails wrenched asunder by laceration. Whatever has proceeded from the womb cannot live and breathe in its detached condition, but loses the substance of health.
