with the subtlest of all weapons of offence and defence, and with an inexhaustible store of sophistical arguments of the most plausible aspect. The question of the real bearing upon theology of the influence exerted by the teaching of Philo's contemporary, Jesus of Nazareth, is one upon which it is not germane to my present purpose to enter. I take it simply as an unquestionable fact that his immediate disciples, known to their countrymen as "Nazarenes," were regarded as, and considered themselves to be, perfectly orthodox Jews, belonging to the puritanic or pharisaic section of their people, and differing from the rest only in their belief that the Messiah had already come. Christianity, it is said, first became clearly differentiated at Antioch, and it separated itself from orthodox Judaism by denying the obligation of the rite of circumcision and of the food prohibitions, prescribed by the law. Henceforward theology became relatively stationary among the Jews, [34] and the history of its rapid progress in a new course of evolution is the history of the Christian Churches, orthodox and heterodox. The steps in this evolution are obvious. The first is the birth of a new theological scheme arising out of the union of elements derived from Greek philosophy with elements derived from Israelitic theology. In the fourth Gospel, the Logos, raised to a somewhat higher degree of personification than in the Alexandrian theosophy, is identified with Jesus of Nazareth. In the Epistles, especially the later of those attributed to Paul, the Israelitic ideas of the Messiah and of sacrificial atonement coalesce with one another and with the embodiment of the Logos in Jesus, until the apotheosis of the Son of man is almost, or quite, effected. The history of Christian dogma, from Justin to Athanasius, is a record of continual progress in the same direction, until the fair body of religion, revealed in almost naked purity by the prophets, is once more hidden under a new accumulation of dogmas and of ritual practices of which the primitive Nazarene knew nothing; and which he would probably have regarded as blasphemous if he could have been made to understand them.
