Jesus von Nazaret
The quest for the historical Jesus began with the work of Hermann Samuel Reimarus in the 18th century. Two books, both called "The Life of Jesus" were written by David Strauss, published in German in 1835–36, and Ernest Renan, published in French in 1863. The "Historical Jesus" is conceptually different than the "Christ of Faith". The former is physical, while the latter metaphysical. The "Historical Jesus" is based on historical evidence. Every time a new scroll is unearthed or new Gospel fragment is found, the "Historical Jesus" is modified. And because so much has been lost, we can never know him completely.
