Jesus really existed? This simple question if may ask any person who has an ounce of common sense and that belong to any religion except mine. In fact, if Jesus was a historical figure or a myth if you can ask a jew, a Mohammedan, a Buddhist one, and even a Shinto animist Togo or a follower of the goddess Kahli but to me, that I am a Christian, is not allowed. In fact, everything that we Christians know about Jesus we have been taught by our Church. In Italy, with rare exceptions, the matter has been dealt with only by scholars of proven faith according to the canons of the Pontifical Commission for Biblical Studies, and the Propaganda Fides that are part of the ecclesiastical hierarchy and the Congregation of the Holy Office. But I believe the time is ripe for groped a synthesis of all this controversial subject with the aid of new technologies and the latest findings. In order not to confuse us, we will use the razor of William of Ockham, the pragmatic philosopher who used it to figure out what topics would and could discuss: anything that you could cut with a razor was worthy of analysis, all the rest was left to Metaphysics."
