It is not necessary here to repeat how Mary was afterwards declared to be the mother of God; how the consubstantiality of the Father and the "word" was established; as also the proceeding of the "_pneuma_," the divine organ of the divine _Logos_; as also the two natures and two wills resulting from the hypostasis; and lastly, the superior manducation--the soul nourished as well as the body, with the flesh and blood of the God-man, adored and eaten in the form of bread, present to the eyes, sensible to the taste, and yet annihilated. All mysteries have been sublime. In the second century devils began to be cast out in the name of Jesus; before they were cast out in the name of Jehovah or Ihaho; for St. Matthew relates that the enemies of Jesus having said that He cast out devils in the name of the prince of devils, He answered, "If I cast out devils by Beelzebub, by whom do your sons cast them out?" It is not known at what time the Jews recognized Beelzebub, who was a strange god, as the prince of devils; but it is known, for Josephus tells us, that there were at Jerusalem exorcists appointed to cast out devils from the bodies of the possessed; that is, of such as were attacked by singular maladies, which were then in a great part of the world attributed to the malific genii. These demons were then cast out by the true pronunciation of Jehovah, which is now lost, and by other ceremonies now forgotten. This exorcism by Jehovah or by the other names of God, was still in use in the first ages of the church. Origen, disputing against Celsus, says to him: "If, when invoking God, or swearing by Him, you call Him 'the God of Abraham, Isaac, and Jacob,' you will by those words do things, the nature and force of which are such that the evil spirits submit to those who pronounce them; but if you call him by another name, as 'God of the roaring sea,' etc., no effect will be produced. The name of 'Israel,' rendered in Greek, will work nothing; but pronounce it in Hebrew with the other words required, and you will effect the conjuration." The same Origen has these remarkable words: "There are names which are powerful from their own nature. Such are those used by the sages of Egypt, the Magi of Persia, and the Brahmins of India. What is called 'magic,' is not a vain and chimerical art, as the Stoics and Epicureans pretend. The names '_Sabaoth_' and '_Adonai_' were not made for created beings, but belong to a mysterious theology which has reference to the Creator; hence the virtue of these names when they are arranged and pronounced according to rule." Origen, when speaking thus, is not giving his private opinion; he is but repeating the universal opinion.
