At the beginning of the Christian era, we see three great source of which is, in principle, could develop a tradition of mysticism - a doctrine or speculative system of Greece, of the East and of Christianity, ie, the early apostolic tradition... In fact, all three sources have contributed, however, where Christianity has breathed new energy into transcendentalism, Greek and oriental type of thinking gave rise to the main form in which he was able to speak. By its very nature, Christianity is deeply mystical. If you leave outside our discussion of the identity of the founder of the religion, it is already binding. Paul and the author of the Fourth Gospel, - one of the earliest missionaries to Christianity - are an obvious example of the mystics of the highest rank. Much of the spiritual history of early Christianity is still unknown, but the available evidence, we find many, though scattered indications that the mystic life was perfectly natural for the Church and innate mysticism did not need to look for inspiration outside their faith. Not only is the message of St. Paul and the writings of St. John the Divine, but also the extant earliest liturgical pieces such examples of primitive religious poetry as 'Solomon Odes' and 'Hymn of Jesus', show how congenial a mystical expression suited to the image of the Church thought and how easy it Church could absorb and convert the mystic elements Essene philosophy and Orphic mysteries and the Neo-Platonism.
