(g) Justinian, Digest, I, 5:17.
The edict of Caracalla (Marcus Aurelius Antoninus) conferring Roman citizenship upon all free inhabitants of the Empire has not been preserved. It is known only from a brief extract from the twenty-second book of Ulpian's work on the Prætorian Edict, contained in the Digest of Justinian.
Those who were in the Roman world were made Roman citizens by the constitution of the Emperor Antoninus.
§ 35. Religious Syncretism in the Third Century
In the third century religious syncretism took two leading forms—the Mithraic worship, which spread rapidly throughout the Empire, and the fashionable interest in novel religions fostered by the imperial court. Mithraism was especially prevalent in the army, and at army posts have been found numerous remains of sanctuaries, inscriptions, etc. It was by far the purest of the religions that invaded the Roman Empire, and drew its leading ideas from Persian sources. The fashionable court interest in novel religions seems not to have amounted to much as a positive religious force, which Mithraism certainly was, though on account of it Christianity was protected and even patronized by the ladies of the imperial household. Among the works produced by this interest was the Life of Apollonius of Tyana, written by Philostratus at the command of the Empress Julia Domna. Apollonius was a preacher or teacher of ethics and the Neo-Pythagorean philosophy in the first century, ob. A. D. 97.
Additional source material: Philostratus, Life of Apollonius (the latest English translation, by F. C. Conybeare, with Greek text in the Loeb Classical Library, 1912).
Mithraic Prayer, Albrecht Dietrich, Eine Mithrasliturgie, Leipsic, 1903.
The following prayer is the opening invocation of what appears to be a Mithraic liturgy, and may date from a period earlier than the fourth century. It gives, as is natural, no elaborated statement of Mithraic doctrine, but, as in all prayer, much is implied in the forms used and the spirit of the religion breathed through it. The combination has already begun as is shown by the doctrine of the four elements. It should be added that Professor Cumont does not regard it as a Mithraic liturgy at all, but accounts for the distinct mention of the name Mithras, which is to be found in some parts, to a common tendency of semi-magical incantations to employ as many deities as possible.
First Origin of my origin, first Beginning of my beginning, Spirit of Spirit, first of the spirit in me. Fire which to compose me has been given of God, first of the fire in me. Water of water, first of the water in me. Earthy Substance of earthy substance, first of the earthy substance, the entire body of me, N. N. son of N. N., completely formed by an honorable arm and an immortal right hand in the lightless and illuminated world, in the inanimated and the animated. If it seem good to you to restore me to an immortal generation, who am held by my underlying nature, that after this present need which presses sorely upon me I may behold the immortal Beginning with the immortal Spirit, the immortal Water, the Solid and the Air, that I may be born again, by the thought, that I may be consecrated and the holy Spirit may breathe in me, that I may gaze with astonishment at the holy Fire, that I may look upon abysmal and frightful Water of the sun-rising, and the generative Ether poured around may listen to me. For I will to-day look with immortal eyes, I who was begotten a mortal from a mortal womb, exalted by a mighty working power and incorruptible right hand, I may look with an immortal spirit upon the immortal Eon and the Lord of the fiery crowns, purified by holy consecrations, since a little under me stands the human power of mind, which I shall regain after the present bitter, oppressive, and debt-laden need, I, N. N. the son of N. N., according to God's unchangeable decree, for it is not within my power, born mortal, to mount up with the golden light flashes of the immortal illuminator. Stand still, corruptible human nature, and leave me free after the pitiless and crushing necessity.
