All writers agree with Firmicus that the pagans worshiped the _elementa_.[14] Under this term were included not only the four simple substances which by their opposition and blending caused all phenomena of the visible world,[15] but also the stars and in general the elements of all celestial and earthly bodies.[16]
We therefore may in a certain sense speak of the return of paganism to nature worship; but must this transformation be regarded as a retrogression toward a barbarous past, as a relapse to the level of primitive animism? If so, we should be deceived by appearances. Religions do not fall back into infancy as they grow old. The pagans of the fourth century no longer naively considered their gods as capricious genii, as the disordered powers of a confused natural philosophy; they conceived them as cosmic energies whose providential action was regulated in a harmonious system. Faith was no longer instinctive and impulsive, for erudition and reflection had reconstructed the entire theology. In a certain sense it might be said that theology had passed from the fictitious to the metaphysical state, according to the formula of Comte. It was intimately connected with the knowledge of the day, which was cherished by its last votaries with love and pride, as faithful heirs of the ancient wisdom of the Orient and Greece.[17] In many instances it was nothing but a religious form of the cosmology of the { 207} period. This constituted both its strength and its weakness. The rigorous principles of astrology determined its conception of heaven and earth.
The universe was an organism animated by a God, unique, eternal and almighty. Sometimes this God was identified with the destiny that ruled all things, with infinite time that regulated all visible phenomena, and he was worshiped in each subdivision of that endless duration, especially in the months and the seasons.[18] Sometimes, however, he was compared with a king; he was thought of as a sovereign governing an empire, and the various gods then were the princes and dignitaries interceding with the rulers on behalf of his subjects whom they led in some manner into his presence. This heavenly court had its messengers or "angels" conveying to men the will of the master and reporting again the vows and petitions of his subjects. It was an aristocratic monarchy in heaven as on earth.[19] A more philosophic conception made the divinity an infinite power impregnating all nature with its overflowing forces. "There is only one God, sole and supreme," wrote Maximus of Madaura about 390, "without beginning or parentage, whose energies, diffused through the world, we invoke under various names, because we are ignorant of his real name. By successively addressing our supplications to his different members we intend to honor him in his entirety. Through the mediation of the subordinate gods the common father both of themselves and of all men is honored in a thousand different ways by mortals who are thus in accord in spite of their discord."[20]
