Ignatius of Antioch
Follow your bishop, every one of you, as obediently as Jesus Christ followed the Father. Obey your clergy too as you would the apostles; give your deacons the same reverence that you would to a command of God. Make sure that no step affecting the Church is ever taken by anyone without the bishop’s sanction. The sole Eucharist you should consider valid is one that is celebrated by the bishop himself, or by some person authorized by him. Where the bishop is to be seen, there let all his people be; just as, wherever Jesus Christ is present, there is the Catholic Church (Letter to the Smyrneans 8:2 [A.D. 110]).
In like manner let everyone respect the deacons as they would respect Jesus Christ, and just as they respect the bishop as a type of the Father, and the presbyters as the council of God and college of the apostles. Without these, it cannot be called a Church. I am confident that you accept this, for I have received the exemplar of your love and have it with me in the person of your bishop. His very demeanor is a great lesson and his meekness is his strength. I believe that even the godless do respect him (Letter to the Trallians 3:1-2 [A. D. 110]).
The Martyrdom of PolycarpWhen finally he concluded his prayer, after remembering all who had at any time come his way – small folk and great folk, distinguished and undistinguished, and the whole Catholic Church throughout the world – the time for departure came. So they placed him on an ass, and brought him into the city on a great Sabbath (The Martyrdom of Polycarp 8 [A.D. 110]).
Irenaeus
The Catholic Church possesses one and the same faith throughout the whole world, as we have already said (Against Heresies 1:10 [A.D. 189]).
Since therefore we have such proofs, it is not necessary to seek the truth among others which it is easy to obtain from the Church; since the apostles, like a rich man [depositing his money] in a bank, lodged in her hands most copiously all things pertaining to the truth: so that every man, whosoever will, can draw from her the water of life. For she is the entrance to life; all others are thieves and robbers. On this account we are bound to avoid them, but to make choice of the things pertaining to the Church with the utmost diligence, and to lay hold of the tradition of the truth. For how stands the case? Suppose there should arise a dispute relative to some important question among us. Should we not have recourse to the most ancient churches with which the apostles held constant intercourse, and learn from them what is certain and clear in regard to the present question? For how should it be if the apostles themselves had not left us writings? Would it not be necessary [in that case] to follow the course of the tradition which they handed down to those to whom they did commit the churches? (ibid. 3:4).
Tertullian
Where was Marcion then, that shipmaster of Pontus, the zealous student of Stoicism? Where was Valentinus then, the disciple of Platonism? For it is evident that those men lived not so long ago – in the reign of Antoninus for the most part – and that they at first were believers in the doctrine of the Catholic Church, in the church of Rome under the episcopate of the blessed Eleutherus, until on account of their ever restless curiosity, with which they even infected the brethren, they were more than once expelled (On the Prescription Against Heretics 22,30 [A.D.200])
Clement of Alexandria
A multitude of other pieces of advice to particular persons is written in the holy books: some for presbyters, some for bishops and deacons; and others for widows, of whom we shall have opportunity to speak elsewhere (The Instructor of Children 3:12:97:2 [pre-A.D. 202]).
Even here in the Church the gradations of bishops, presbyters, and deacons happen to be imitations, in my opinion, of the angelic glory and of that arrangement which, the Scriptures say, awaits those who have followed in the footsteps of the apostles and who have lived in complete righteousness according to the gospel (Stromateis 6:13:107:2 [post-A.D. 202]).
Hippolytus
When a deacon is to be ordained, he is chosen after the fashion of those things said above, the bishop alone in like manner imposing his hands upon him as we have prescribed. In the ordaining of a deacon, this is the reason why the bishop alone is to impose his hands upon him: He is not ordained to the priesthood, but to serve the bishop and to fulfill the bishop’s command. He has no part in the council of the clergy, but is to attend to his own duties and is to acquaint the bishop with such matters as are needful. . . . On a presbyter [priest], however, let the presbyters impose their hands because of the common and like Spirit of the clergy. Even so, the presbyter has only the power to receive [the Spirit], and not the power to give [the Spirit]. That is why a presbyter does not ordain the clergy; for at the ordaining of a presbyter, he but seals while the bishop ordains. (Apostolic Tradition 9 [ca. A.D. 215]).
Origen
Not fornication only, but even marriages make us unfit for ecclesiastical honors; for neither a bishop, nor a presbyter, nor a deacon, nor a widow is able to be twice married (Homilies on Luke, 17 [ca. A.D. 235]).
Cyprian
The spouse of Christ cannot be defiled; she is uncorrupted and chaste. She knows one home . . . Does anyone believe that this unity which comes from divine strength, which is closely connected with the divine sacraments, can be broken asunder in the Church and be separated by the divisions of colliding wills? He who does not hold this unity, does not hold the law of God, does not hold the faith of the Father and the Son, does not hold life and salvation (On the Unity of the Catholic Church 6 [A.D. 251]).
Peter speaks there, on whom the Church was to be built, teaching and showing in the name of the Church, that although a rebellious and arrogant multitude of those who will not hear or obey may depart, yet the Church does not depart from Christ; and they are the Church who are a people united to the priest, and the flock which adheres to its pastor. Whence you ought to know that the bishop is in the Church, and the Church in the bishop; and if any one be not with the bishop, that he is not in the Church, and that those flatter themselves in vain who creep in, not having peace with God’s priests, and think that they communicate secretly with some; while the 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 (Letters 66 [A.D. 253]).
Ignatius of Antioch
Be not deceived, my brethren: If anyone follows a maker of schism [i.e., is a schismatic], he does not inherit the kingdom of God; if anyone walks in strange doctrine [i.e., is a heretic], he has no part in the Passion [of Christ]. Take care, then, to use one Eucharist, so that whatever you do, you do according to God: For there is one flesh of our Lord Jesus Christ, and one cup in the union of his blood; one altar, as there is one bishop, with the presbytery and my fellow servants, the deacons (Letter to the Philadelphians 3:3-4:1 [A.D. 110]).Justin Martyr We have been taught that Christ is the first-begotten of God, and we have declared him to be the Logos of which all mankind partakes [John 1:9]. Those, therefore, who lived according to reason [Greek, logos} were really Christians, even though they were thought to be atheists, such as, among the Greeks, Socrates, Heraclitus, and others like them. . . . Those who lived before Christ but did not live according to reason [logos] were wicked men, and enemies of Christ, and murderers of those who did live according to reason [logos], whereas those who lived then or who live now according to reason [logos] are Christians. Such as these can be confident and unafraid (First Apology 46 [A.D. 151]).Irenaeus In the Church God has placed apostles, prophets, teachers, and every other working of the Spirit, of whom none of those are sharers who do not conform to the Church, but who defraud themselves of life by an evil mind and even worse way of acting. Where the Church is, there is the Spirit of God; where the Spirit of God is, there is the Church and all grace (Against Heresies 3:24:1 [A.D. 189]).[The spiritual man] shall also judge those who give rise to schisms, who are destitute of the love of God, and who look to their own special advantage rather than to the unity of the Church; and who for trifling reasons, or any kind of reason which occurs to them, cut in pieces and divide the great and glorious body of Christ, and so far as in them lies, destroy it — men who prate of peace while they give rise to war, and do in truth strain out a gnat, but swallow a camel. For they can bring about no “reformation” of enough importance to compensate for the evil arising from their schism. . . . True knowledge is that which consists in the doctrine of the apostles, and the ancient constitution of the Church throughout all the world, and the distinctive manifestation of the body of Christ according to the successions of the bishops, by which they have handed down that Church which exists in every place [i.e., the Catholic Church] (ibid., 4:33:7-8).Origen There was never a time when God did not want men to be just; he was always concerned about that. Indeed, he always provided beings endowed with reason with occasions for practicing virtue and doing what is right. In every generation the Wisdom of God descended into those souls which he found holy and made them to be prophets and friends of God (Against Celsus 4:7 [A.D. 248]).If someone from this people wants to be saved, let him come into this house so that he may be able to attain his salvation. . . . Let no one, then, be persuaded otherwise, nor let anyone deceive himself: Outside of this house, that is, outside of the Church, no one is saved; for, if anyone should go out of it, he is guilty of his own death (Homilies on Joshua 3:5 [A.D. 250]).Cyprian of Carthage Whoever is separated from the Church and is joined to an adulteress [a schismatic church] is separated from the promises of the Church, nor will he that forsakes the Church of Christ attain to the rewards of Christ. He is an alien, a worldling, and an enemy. He cannot have God for his Father who has not the Church for his mother (The Unity of the Catholic Church 6, 1st ed. [A.D. 251]).Let them not think that the way of life or salvation exists for them, if they have refused to obey the bishops and priests, since the Lord says in the book of Deuteronomy: “And any man who has the insolence to refuse to listen to the priest or judge, whoever he may be in those days, that man shall die” [Deut. 17:12-13]. And then, indeed, they were killed with the sword . . . but now the proud and insolent are killed with the sword of the Spirit, when they are cast out from the Church. For they cannot live outside, since there is only one house of God, and there can be no salvation for anyone except in the Church (Letters 61[4]:4 [A.D. 253]).The baptism of public witness [desire] and of blood cannot profit a heretic [one who holds the faith and then abandons it] unto salvation, because there is no salvation outside the Church (Letters 72 [73]:21 [A.D. 253]).Lactanius It is, therefore, the Catholic Church alone that retains true worship. This is the fountain of truth; this, the domicile of faith; this, the temple of God. Whoever does not enter there or whoever does not go out from there, he is a stranger to the hope of life and salvation. . . Because, however, all the various groups of heretics are confident that they are the Christians and think that theirs is the Catholic Church, let it be known that this is the true Church, in which there is confession and penance and which takes a health-promoting care of the sins and wounds to which the weak flesh is subject (Divine Institutes 4:30:11-13 [A.D. 307]).Jerome Heretics bring sentence upon themselves since they by their own choice withdraw from the Church, a withdrawal which, since they are aware of it, constitutes damnation. Between heresy and schism there is this difference: that heresy involves perverse doctrine, while schism separates one from the Church on account of disagreement with the bishop. Nevertheless, there is no schism which does not trump up a heresy to justify its departure from the Church (Commentary on Titus 3:10-11 [A.D. 386]).Augustine We believe also in the holy Church, that is, the Catholic Church. For heretics violate the faith itself by a false opinion about God; schismatics, however, withdraw from fraternal love by hostile separations, although they believe the same things we do. Consequently; neither heretics nor schismatics belong to the Catholic Church, not heretics, because the Church loves God, and not schismatics, because the Church loves neighbor (Faith and the Creed 10:21 [A.D. 393]).When we speak of within and without in relation to the Church, it is the position of the heart that we must consider, not that of the body. . . All who are within [the Church] in heart are saved in the unity of the ark (On Baptism, Against the Donatists 5:28[39] [A.D. 400]).
