Nearly two thousand years have passed since the Son of man taught the way, the truth and the life of mankind. He brought health to the sick, wisdom to the ignorant and happiness to those in misery. He conquered half of humanity and the whole of the civilization of the West. This fact proves the eternal vitality of the Master's words, and their supreme and incomparable value. The content of this book represents only about a third of the complete manuscripts which exist in Aramaic in the Secret Archives of the Vatican and in old Slavonic in the Royal Archives of the Habsburgs (now the property of the Austrian Government). We owe the existence of these two versions to the Nestorian priests who, under pressure of the advancing hordes of Genghis Khan, were forced to flee from the East towards the West, bearing all their ancient scriptures and ikons with them. The ancient Aramaic texts date from the 3rd century after Christ, while the old Slavonic version is a literal translation of the former. Exactly how the texts traveled from Palestine to the interior of Asia into the hands of the Nestorian priests, archeologists are not yet able to reconstruct for us. We have nothing to add to this text. It speaks for itself. The reader who studies the pages that follow with concentration, will feel the eternal vitality and powerful evidence of these profound truths which mankind needs today more urgently than ever before.
