0 ENCYCLICAL OF POPE PIUS XI ON ATHEISTIC COMMUNISM TO THE PATRIARCHS, PRIMATES, ARCHBISHOPS, BISHOPS, AND OTHER ORDINARIES IN PEACE AND COMMUNION WITH THE APOSTOLIC SEE. Venerable Brethren, Health and Apostolic Benediction. The promise of a Redeemer brightens the first page of the history of mankind, and the confident hope aroused by this promise softened the keen regret for a paradise which had been lost. It was this hope that accompanied the human race on its weary journey, until in the fullness of time the expected Savior came to begin a new universal civilization, the Christian civilization, far superior even to that which up to this time had been laboriously achieved by certain more privileged nations.
