Sacred Scripture teaches the human family what the experience of the ages confirms: that while human progress is a great advantage to man, it brings with it a strong temptation. For when the order of values is jumbled and bad is mixed with the good, individuals and groups pay heed solely to their own interests, and not to those of others. Thus it happens that the world ceases to be a place of true brotherhood. In our own day, the magnified power of humanity threatens to destroy the race itself…
Hence if anyone wants to know how this unhappy situation can be overcome, Christians will tell him that all human activity…must be purified and perfected by the power of Christ's cross and resurrection. For redeemed by Christ and made a new creature in the Holy Spirit, man is able to love the things themselves created by God, and ought to do so. He can receive them from God… Thus He entered the world's history as a perfect man, taking that history up into Himself and summarizing it.(11) He Himself revealed to us that "God is love" (1 John 4:8) and at the same time taught us that the new command of love was the basic law of human perfection and hence of to worlds transformation. To those, therefore, who believe in divine love, He gives assurance that the way of love lies open to men and that the effort to establish a universal brotherhood is not a hopeless one. He cautions them at the same time that this charity is not something to be reserved for important matters, but must be pursued chiefly in the ordinary circumstances of life. Undergoing death itself for all of us sinners,(12) He taught us by example that we too must shoulder that cross which the world and the flesh inflict upon those who search after peace and justice.
