Where the bishop, there the Church: St. Ignatius of Antioch
When St. Peter left Antioch to move to Rome, St. Ignatius became the new bishop there, where the followers of the Lord were first called Christians. Ignatius served as bishop there in diligence and holiness, until he was arrested and sent to Rome for trial and for martyrdom. On his way to Rome, he wrote seven letters to individuals and to local Churches along the way, reminding them of the truths of the faith, seeking their prayers, and asking especially the Romans not to do anything to prevent the workings of "justice" in his case. These letters still lift us up in our days, and the Church gives us many opportunities to read them in the Liturgy of the Hours.
Some of the things St. Ignatius wrote:
[to the Magnesians:]
I exhort you to study to do all things with a divine harmony, while your bishop presides in the place of God, and your presbyters in the place of the assembly of the apostles, along with your deacons, who are most dear to me, and are entrusted with the ministry of Jesus Christ, who was with the Father before the beginning of time, and in the end was revealed. Do ye all then, imitating the same divine conduct, pay respect to one another, and let no one look upon his neighbour after the flesh, but do ye continually love each other in Jesus Christ. Let nothing exist among you that may divide you ; but be ye united with your bishop, and those that preside over you, as a type and evidence of your immortality.
As therefore the Lord did nothing without the Father, being united to Him, neither by Himself nor by the apostles, so neither do ye anything without the bishop and presbyters. Neither endeavour that anything appear reasonable and proper to yourselves apart; but being come together into the same place, let there be one prayer, one supplication, one mind, one hope, in love and in joy undefiled. There is one Jesus Christ, than whom nothing is more excellent. Do ye therefore all run together as into one temple of God, as to one altar, as to one Jesus Christ, who came forth from one Father, and is with and has gone to one.
[to Polycarp, bishop of Smyrna:]
I entreat thee, by the grace with which thou art clothed, to press forward in thy course, and to exhort all that they may be saved. Maintain thy position with all care, both in the flesh and spirit. Have a regard to preserve unity, than which nothing is better. Bear with all even as the Lord does with thee. Support all in love, as also thou doest. Give thyself to prayer without ceasing. Implore additional understanding to what thou already hast. Be watchful, possessing a sleepless spirit. Speak to every man separately, as God enables thee. Bear the infirmities of all, as being a perfect athlete [in the Christian life], even as does the Lord of all. For says [the Scripture], "He Himself took our infirmities, and bare our sicknesses." Where the labour is great, the gain is all the more.
If thou lovest the good disciples, no thanks are due to thee on that account; but rather seek by meekness to subdue the more troublesome. Every kind of wound is not healed with the same plaster. Mitigate violent attacks [of disease] by gentle applications. Be in all things "wise as a serpent, and harmless always as a dove." For this purpose thou art composed of both soul and body, art both fleshly and spiritual, that thou mayest correct those [evils] that present themselves visibly before thee; and as respects those that are not seen, mayest pray that these should be revealed to thee, so that thou mayest be wanting in nothing, but mayest abound in every gift. The times call upon thee to pray. For as the wind aids the pilot of a ship, and as havens are advantageous for safety to a tempest-tossed vessel, so is also prayer to thee, in order that thou mayest attain to God. Be sober as an athlete of God, whose will is immortality and eternal life; of which thou art also persuaded.
[to the Trallians:]
For, since ye are subject to the bishop as to Jesus Christ, ye appear to me to live not after the manner of men, but according to Jesus Christ, who died for us, in order, by believing in His death, ye may escape from death. It is therefore necessary that, as ye indeed do, so without the bishop ye should do nothing, but should also be subject to the presbytery, as to the apostle of Jesus Christ, who is our hope, in whom, if we live, we shall [at last] be found. It is fitting also that the deacons, as being [the ministers] of the mysteries of Jesus Christ, should in every respect be pleasing to all. For they are not ministers of meat and drink, but servants of the Church of God. They are bound, therefore, to avoid all grounds of accusation [against them], as they would do fire.
Do ye therefore, clothing yourselves with meekness, become the imitators of His sufferings, and of His love, wherewith He loved us when He gave Himself a ransom for us, that He might cleanse us by His blood from our old ungodliness, and bestow life on us when we were almost on the point of perishing through the depravity that was in us. Let no one of you, therefore, cherish any grudge against his neighbour. For says our Lord, "Forgive, and it shall be forgiven unto you." Give no occasion to the Gentiles, lest "by means of a few foolish men the word and doctrine [of Christ.] be blasphemed." For says the prophet, as in the person of God, "Woe to him by whom my name is blasphemed among the Gentiles."
[to the Philadelphians:]
Wherefore, as children of light and truth, flee from division and wicked doctrines; but where the shepherd is, there do ye as sheep follow. For there are many wolves that appear worthy of credit, who, by means of a pernicious pleasure, carry captive those that are running towards God; but in your unity they shall have no place.
Keep yourselves from those evil plants which Jesus Christ does not tend, because they are not the planting of the Father. Not that I have found any division among you, but exceeding purity. For as many as are of God and of Jesus Christ are also with the bishop. And as many as shall, in the exercise of repentance, return into the unity of the Church, these, too, shall belong to God, that they may live according to Jesus Christ. Do not err, my brethren. If any man follows him that makes a schism in the Church, he shall not inherit the kingdom of God. If any one walks according to a strange opinion, he agrees not with the passion [of Christ.].
Take ye heed, then, to have but one Eucharist. For there is one flesh of our Lord Jesus Christ, and one cup to [show forth] the unity of His blood; one altar; as there is one bishop, along with the presbytery and deacons, my fellow-servants: that so, whatsoever ye do, ye may do it according to [the will of] God.
My brethren, I am greatly enlarged in loving you; and rejoicing exceedingly [over you], I seek to secure your safety. Yet it is not I, but Jesus Christ, for whose sake being bound I fear the more, inasmuch as I am not yet perfect. But your prayer to God shall make me perfect, that I may attain to that portion which through mercy has been allotted me, while I flee to the Gospel as to the flesh of Jesus, and to the apostles as to the presbytery of the Church. And let us also love the prophets, because they too have proclaimed the Gospel, and placed their hope in Him, and waited for Him; in whom also believing, they were saved, through union to Jesus Christ, being holy men, worthy of love and admiration, having had witness borne to them by Jesus Christ, and being reckoned along with [us] in the Gospel of the common hope.
