On When the Roman Empire Became Orthodox

The Edict of Thessalonica (Cunctos Populos) 380 a.d.

EMPERORS GRATIAN, VALENTINIAN AND THEODOSIUS AUGUSTI. EDICT TO THE PEOPLE OF CONSTANTINOPLE.

It is our desire that all the various nations which are subject to our Clemency and Moderation, should continue to profess that religion which was delivered to the Romans by the divine Apostle Peter, as it has been preserved by faithful Tradition, and which is now professed by the Pontiff Damasus and by Peter, Bishop of Alexandria, a man of apostolic holiness. According to the apostolic teaching and the doctrine of the Gospel, let us believe in the one Deity of the Father, the Son and the Holy Spirit, in equal majesty and in a Holy Trinity. We authorize the followers of this law to assume the title of Catholic Christians; but as for the others, since, in our judgment they are foolish madmen, we decree that they shall be branded with the ignominious name of heretics, and shall not presume to give to their conventicles the name of churches. They will suffer in the first place the chastisement of the divine condemnation and in the second the punishment of our authority which in accordance with the will of Heaven we shall decide to inflict.

GIVEN IN THESSALONICA ON THE THIRD DAY FROM THE CALENDS OF MARCH, DURING THE FIFTH CONSULATE OF GRATIAN AUGUSTUS AND FIRST OF THEODOSIUS AUGUSTUS (Codex Theodosianus, xvi.1.2)

St. Peter on Creation

St. Peter of Alexandria died ca. 311

The things which pertain to the divinity and humanity of the Second Man from heaven, in what has been written above, according to the blessed apostle, we have explained; and now we have thought it necessary to explain the things which pertain to the first man, who is of earth and earthy, being about, namely, to demonstrate this, that he was created at the same time one and the same, although sometimes he is separately designated as the man external and internal. For if, according to the Word of salvation, He who made what is without, made also that which is within, He certainly, by one operation, and at the same time, made both, on that day, indeed, on which God said, Let us make man in our image, after our likeness; (Gen. 1:26) whence it is manifest that man was not formed by a conjunction of the body with a certain pre-existent type. For if the earth, at the bidding of the Creator, brought forth the other animals endowed with life, much rather did the dust which God took from the earth receive a vital energy from the will and operation of God. (Fragments, 6)
