From the image of the fish in the early Christian catacombs to the icons of churches, and from the star of Bethlehem to the doctrinal differences between the Eastern and Western Church, centuries of crimes, counter-crimes, visions, miracles, philosophy, theology, and science have passed. This book unravels the thread from the beginning, following the traces of J.C.T.H.Y.S. (Jesus Christ, Son of God, Savior), combining national with Jewish and theological with scientific sources, giving the reader a comprehensive view of the historicity of the events of the life of Jesus Christ, as well as the social, philosophical, and scientific influences that shaped, or in the future will question, the perception of what we call "Christian doctrine". Within the framework of a new scientific understanding of how the dynamic relationship between Positive Sciences and Theology should be formed, this book attempts, through research, to present both the scientific perspective and the theological thought without the "overlaps" that have proven detrimental to understanding the essence of the teaching of J.C.T.H.Y.S.
