Mystic Christianity [EPUB ebook] 

The true story of the life of Jesus of Nazareth has never been unfolded to the world, either in the accepted Gospels or in the Apocrypha, although a few stray hints may be found in some of the commentaries written by the ante-Nicene Fathers. The facts concerning His identity and mission are among the priceless mysteries preserved to this day in the secret vaults beneath the “Houses of the Brethren”.
To a few of the Knights Templars, who were initiated into the arcana of the Druses, Nazarenes, Essenes, Johannites, and other sects still inhabiting the remote and inaccessible fastnesses of the Holy Land, part of the strange story was told. The knowledge of the Templars concerning the early history of Christianity was undoubtedly one of the main reasons for their persecution and final annihilation.
The discrepancies in the writings of the early Church Fathers not only are irreconcilable, but demonstrate beyond question that even during the first five centuries after Christ these learned men had for the basis of their writings little more substantial than folklore and hearsay.
