One Eucharist

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. I have confidence of you in the Lord, that ye

Avoid schisms. Remain with the bishop.

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.

Trinity and Holy Orders

They introduce God as a Being unknown; they suppose Christ to be unbegotten; and as to the Spirit, they do not admit that He exists. Some of them say that the Son is a mere man, and that the Father, Son, and Holy Spirit are but the same person, and that the creation is the work of God, not by Christ, but by some other strange power.

Be on your guard, therefore, against such persons. And this will be the case with you if you are not puffed up, and continue in intimate union with Jesus Christ our God, and the bishop, and the enactments of the apostles. He that is within the altar is pure, but he that is without is not pure; that is, he who does anything apart from the bishop, and presbytery, and deacons, such a man is not pure in his conscience.

Ignatius of Antioch
Epistle to the Trallians
Chapter VI – VII

There is no Church without Holy Orders

In like manner, let all reverence the deacons as an appointment of Jesus Christ, and the bishop as Jesus Christ, who is the Son of the Father, and the presbyters as the sanhedrim of God, and assembly of the apostles. Apart from these, there is no Church.

The Trinity, the Orders, and the Flesh and Spirit

Study, therefore, to be established in the doctrines of the Lord and the apostles, that so all things, whatsoever ye do, may prosper both in the flesh and spirit; in faith and love; in the Son, and in the Father, and in the Spirit; in the beginning and in the end; with your most admirable bishop, and the well-compacted spiritual crown of your presbytery, and the deacons who are according to God. Be ye subject to the bishop, and to one another, as Jesus Christ to the Father, according to the flesh, and the apostles to Christ, and to the Father, and to the Spirit; that so there may be a union both fleshly and spiritual.

Do all things in harmony with the Holy Orders

Since therefore I have, in the persons before mentioned, beheld the whole multitude of you in faith and love, 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.

Chapter VI

The Father is the bishop of us all

Now it becomes you also not to treat your bishop too familiarly on account of his youth, but to yield him all reverence, having respect to the power of God the Father, as I have known even holy presbyters do, not judging rashly, from the manifest youthful appearance of their bishop, but as being themselves prudent in God, submitting to him, or rather not to him, but to the Father of Jesus Christ, the bishop of us all.

Eucharist—the medicine of immortality

Especially will I do this if the Lord make known to me that you come together man by man in common through grace, individually, in one faith, and in Jesus Christ, who was of the seed of David according ot the flesh, being both the Son of man and the Son of God, so that you obey the bishop and the presbytery with an undivided mind, breaking on and the same bread, which is the medicine of immortality, and the antidote to prevent us from dying, but which causes that we should live forever in Jesus Christ.
