Apostolic Constitutions, Book VI 11

1But we, who are the children of God and the sons of peace, do preach the holy and right word of piety, and declare one only God, the Lord of the law and of the prophets, the Maker of the world, the Father of Christ; not a being that caused Himself, or begot Himself, as they suppose, but eternal, and without original, and inhabiting light inaccessible; not two or three, or manifold, but eternally one only; not a being that cannot be known or spoken of, but who was preached by the law and the prophets; the Almighty, the Supreme Governor of all things, the All-powerful Being; the God and Father of the Only-begotten, and of the First-born of the whole creation; one God, the Father of one Son, not of many; the Maker of one Comforter by Christ, the Maker of the other orders, the one Creator of the several creatures by Christ, the same their Preserver and Legislator by Him; the cause of the resurrection, and of the judgment, and of the retribution which shall be made by Him: that this same Christ was pleased to become man, and went through life without sin, and suffered, and rose from the dead, and returned to Him that sent Him. We also say that every creature of God is good, and nothing abominable; that everything for the support of life, when it is partaken of righteously, is very good: for, according to the Scripture, all things were very good. We believe that lawful marriage, and the begetting of children, is honourable and undefiled; for difference of sexes was formed in Adam and Eve for the increase of mankind. We acknowledge with us a soul that is incorporeal and immortal — not corruptible as bodies are, but immortal, as being rational and free. We abhor all unlawful mixtures, and that which is practised by some against nature as wicked and impious. We profess there will be a resurrection both of the just and unjust, and a retribution. We profess that Christ is not a mere man, but God the Word, and man the Mediator between God and men, the High Priest of the Father; nor are we circumcised with the Jews, as knowing that He has come to whom the inheritance was reserved, and on whose account the families were kept distinct — the expectation of the Gentiles, Jesus Christ, who sprang out of Judah, the Son from the branch, the flower from Jesse, whose government is upon His shoulder.
