I tend to think that the words of Emeritus Pope Benedict in his book back in 1969 are prophetic..........a grim scenario for some........for others it is a real message of hope for today and the future.  I am writing with a wrist brace, please excuse any typos. The following excerpt is from Cardinal Ratzinger's book (Emeritus Pope Benedict) "Faith and The Future".  Original publication date 1969.  The text is from Catholic Education Resource Centre (CERC).
