"Every person is responsible for his deeds. Christians in the Catholic Church, and not just in Poland, pray for forgiveness for sins of thought and deed, including also the sin of failing to offer help, and of indifference toward evil. Not just wicked deeds or words but also passivity and not getting involved in good deeds are sins. Young people should arrange their lives so that they are content with themselves. And they can achieve satisfaction by knowing that they have acted in a just manner."
January 1, 1970
