Dominum et Vivificantem: On the Holy Spirit in the Life of the Church and the World
38 For in spite of all the witness of creation and of the salvific economy inherent in it, the spirit of darkness is capable of showing God as an enemy of his own creature, and in the first place as an enemy of man, as a source of danger and threat to man. In this way Satan manages to sow in man's soul the seed of opposition to the one who "from the beginning" would be considered as man's enemy-and not as Father. Man is challenged to become the adversary of God! The analysis of sin in its original dimension indicates that, through the influence of the "father of lies," throughout the history of humanity there will be a constant pressure on man to reject God, even to the point of hating him: "Love of self to the point of contempt for God," as St. Augustine puts it. Man will be inclined to see in God primarily a limitation of himself, and not the source of his own freedom and the fullness of good. We see this confirmed in the modern age, when the atheistic ideologies seek to root out religion on the grounds that religion causes the radical "alienation" of man, as if man were dispossessed of his own humanity when, accepting the idea of God, he attributes to God what belongs to man, and exclusively to man! Hence a process of thought and historico-sociological practice in which the rejection of God has reached the point of declaring his "death." An absurdity, both in concept and expression! But the ideology of the "death of God" is more a threat to man, as the Second Vatican Council indicates when it analyzes the question of the "independence of earthly affairs" and writes: "For without the Creator the creature would disappear...when God is forgotten the creature itself grows unintelligible." The ideology of the "death of God" easily demonstrates in its effects that on the "theoretical and practical" levels it is the ideology of the "death of man."
