Zealous disciple of Martinez de Pasqually, J.P. Willermoz was expected to confirm the vision of his Master which presents Christ as a prophet who came for the first time in the created universe to organize the original chaos. And then, through several messengers such as Enoch, Noah, Seth, Jesus...he returned several times in the created world to work on the elevation of the mankind's consciousness in order to obtain its reintegration, which is not the case in this book. Without rejecting the position of the Council of Nicaea, J.P. Willermoz proposes in "the Man-God" an original understanding of the nature and mission of Jesus-Christ, known by the Martinists and their masters under the names of the Second Adam or the Grand Architect of the Universe.
