The Loss of the Sense of Sin
18. Over the course of generations, the Christian mind has gained from the Gospel as it is read in the ecclesial community a fine sensitivity and an acute perception of the seeds of death contained in sin, as well as a sensitivity and an acuteness of perception for identifying them in the thousand guises under which sin shows itself. This is what is commonly called the sense of sin.
This sense is rooted in man's moral conscience and is as it were its thermometer. It is linked to the sense of God, since it derives from man's conscious relationship with God as his Creator, Lord and Father. Hence, just as it is impossible to eradicate completely the sense of God or to silence the conscience completely, so the sense of sin is never completely eliminated.
Why has this happened in our time. A glance at certain aspects of contemporary culture can help us to understand the progressive weakening of the sense of sin, precisely because of the crisis of conscience and crisis of the sense of God already mentioned.
"Secularism" is by nature and definition a movement of ideas and behavior which advocates a humanism totally without God, completely centered upon the cult of action and production and caught up in the heady enthusiasm of consumerism and pleasure seeking, unconcerned with the danger of "losing one's soul." This secularism cannot but undermine the sense of sin. At the very most, sin will be reduced to what offends man. But it is precisely here that we are faced with the bitter experience which I already alluded to in my first encyclical namely, that man can build a world without God, but this world will end by turning against him."(101) In fact, God is the origin and the supreme end of man, and man carries in himself a divine seed.(102) Hence it is the reality of God that reveals and illustrates the mystery of man. It is therefore vain to hope that there will take root a sense of sin against man and against human values, if there is no sense of offense against God, namely the true sense of sin.
