The book was written out of the need of a priestly heart, spontaneously, in the face of threats from the global ideologies of the modern world, which are and should be a serious challenge for both the Church and every Catholic. The evil of these ideologies comes from their system of values and thinking, alternative to Christianity, which turns the entire moral and legal order of the world upside down and, as a consequence, can lead to a cultural catastrophe of our civilization. Their common denominator is building a world without God in order to sit on His throne a man who is secularized and liberated from all moral and spiritual limitations. The history of Western civilization knows numerous attempts at this dethronement of God and the secular liberation of mankind. However, never before have similar ideologies taken on a global scale in order to be able to threaten the entire human civilization. And these dangers are dealt with in this book, giving Catholics a basic understanding of them.
