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.

I desire the flesh and blood of Christ

I have no delight in corruptible food, nor in the pleasures of this life. I desire the bread of God, the heavenly bread, the bread of life, which is the flesh of Jesus Christ, the Son of God, who became afterwards of the seed of David and Abraham; and I desire the drink of God, namely His blood, which is incorruptible love and eternal life.

According to the love of Jesus Christ our God

Ignatius, who is also called Theophorus, to the Church which has obtained mercy, through the majesty of the Most High Father, and Jesus Christ, His only-begotten Son; the Church which is beloved and enlightened by the will of Him that wills all things which are according to the love of Jesus Christ our God, which also presides in the place of the region of the Romans, worthy of God, worthy of honor, worthy of the highest happiness, worthy of praise, worthy of obtaining her every desire, worthy of being deemed holy,  and which presides over love, is named from Christ, and from the Father, which I also salute in the name of Jesus Christ, the Son of the Father: to those who are united, both according to the flesh and spirit, to every one of His commandments; who are filled inseparably with the grace of God, and are purified from every strange taint, I wish abundance of happiness unblameably, in Jesus Christ our God.

Chapter I

God is the Savior Himself

Flee, therefore, those evil offshoots of Satan, which produce death-bearing fruit, whereof if any one tastes, he instantly dies. For these men are not the planting of the Father. For if they were, they would appear as branches of the cross, and their fruit would be incorruptible. By it He calls you through His passion, as being His members. The head, therefore, cannot be born by itself, without its members; God, who is the Savior Himself, having promised their union.

Chapter XI

Jesus really died and is God, the judge of the Earth.

He was crucified in reality, and not in appearance, not in imagination, not in deceit. He really died, and was buried, and rose from the dead, even as He prayed in a certain place, saying, “But do Thou, O Lord, raise me up again, and I shall recompense them.” And the Father, who always hears Him, answered and said, “Arise, O God, and judge the earth; for Thou shall receive all the heathen for Thine inheritance.”

God the Word was born of Mary

Mary then did truly conceive a body which had God inhabiting it. And God the Word was truly born of the Virgin, having clothed Himself with a body of like passions with our own. He who forms all men in the womb, was Himself really in the womb, and made for Himself a body of the seed of the Virgin, but without any intercourse of man.
