When was the New Testament, the founding text of Christianity, written? Who wrote it? Under what circumstances and with what objective? At first sight, the question should not be debated since it has been affirmed for more than 2000 years that it is the Evangelists and the Apostles who would have written the founding texts of this new religion, in a concern to transmit the extent of their knowledge on the person of Jesus, his teaching, and his fate. But did these famous authors of the New Testament really exist ? Who were they ? Did they really know Christ ? Where did they live ? What language did they speak ? To try to answer all these questions, the greatest specialists in the study of the holy text, historians, epigraphists, archaeologists, will be called upon to solve the mystery and find the trace of the real authors of the New Testament.
