” … But the internal heresies of the Church were not the only ill effects which the misguided zeal of the fathers, in forcing upon Plato the doctrine of the Trinity, brought about.
Though it is possible, that by pointing out some crude similarity of doctrine, they might have obtajned some converts by rendering Christianity less unpalatable to the philosophical world of that day, yet the weapon was skilfully turned against them, and with unerring effect, when the Pagans took upon them to assert that nothing new had been revealed in Christianity; since, by the confessions of its very advocates, the system was previously contained in the writings of Plato.
In the third century, Ammonius Saccas, universally acknowledged to have been a man of consummate ability, taught that every sect, Christian, Heretic or Pagan, had received the truth, and retained it in their varied legends. He undertook, therefore, to unfold it from them all, and to reconcile every creed.
And from his exertions sprung the celebrated Eclectic school of the later Platonists. Plotinus, Amelius, Olympius, Porphyrius, Jamblichus, Syrianus, and Proclus, were among the celebrated professors who succeeded Ammonius in the Platonic chair, and revived and kept alive the spirit of Paganism, with a bitter enmity to the Gospel, for near three hundred years.
The Platonic schools were at length closed by the edict of Justinian; and seven wise men, the last lights of Platonism, Diogenes, Hermias, Eulalius, Priscianus, Damascius, Isidorus and Simplicius retired indignantly from the persecutions of Justinian, to realize the shadowy dreams of the republic of Plato, under the Persian despotism of Chosroes.16
From the writings of these philosophers is collected the bulk of the Oracles of Zoroaster. A few of them were first published by Ludovicus Tiletanus at Paris, with the commentaries of Pletho, to which were subsequently added those of Psellus. Chief part of them, however, were collected by Franciscus Patricius, and published with the Hermetic books at the end of his Nova Philosophia.
To the labours of Mr. Taylor we are indebted for the addition of about fifty more, and for the references to the works from whence all were extracted. I have arranged them according to the subjects, which are said to be occultly discussed in the Parmenides of Plato, viz.: Cause or God, the Ideal Intelligible or Intellectual world, Particular Souls, and the Material world.
And I have placed under a separate head the Magical and Philosophical precepts and directions. There can be no question but that many of these Oracles are spurious; all those, for instance, which relate to the Intelligible and Intellectual orders, which were confessedly obtained in answers given by dæmons, raised for that purpose by the Theurgists;17 who, as well as all the later Platonists, made pretensions to magic, not only in its refinements, which they were pleased to designate Theurgy, but also in that debased form which we should call common witchcraft.
Nevertheless, several of the Oracles seem to be derived from more authentic sources, and, like the spurious Hermetic books which have come down to us, probably contain much of the pure Sabiasm of Persia, and the doctrines of the Oriental philosophy.”
