It is to be found everywhere and among everyone; it can be both violent and astute. In these last centuries, it has attempted to disintegrate the intellectual, moral, and social unity in the mysterious organism of Christ. It has sought nature without grace, reason without faith, freedom without authority, and, at times, authority without freedom. It is an “enemy” that has become more and more apparent with an absence of scruples that still surprises: Christ yes; the Church no! Afterwards: God yes; Christ no! Finally the impious shout: God is dead and, even, God never existed! And behold now the attempt to build the structure of the world on foundations which we do not hesitate to indicate as the main causes of the threat that hangs over humanity: economy without God, law without God, politics without God.
