In the past, it was possible to destroy a village, a town, a region, even a country. Now it is the whole planet that has come under threat. This fact should compel everyone to face a basic moral consideration; from now on, it is only through a conscious choice and then deliberate policy that humanity will survive.
Pope John Paul IITake heed all of you who have at heart mankind's future! Take heed men and women of good will! May the temptation to seek revenge give way to the courage to forgive; may the culture of life and love render vain the logic of death; may trust once more give breath to the lives of peoples.
Pope John Paul II
