The encyclical letter Laudato Si is available here on the Vatican website.
205. Yet all is not lost. Human beings, while capable of the worst, are also capable of rising above themselves, choosing again what is good, and making a new start, despite their mental and social conditioning. We are able to take an honest look at ourselves, to acknowledge our deep dissatisfaction, and to embark on new paths to authentic freedom. No system can completely suppress our openness to what is good, true and beautiful, or our God-given ability to respond to his grace at work deep in our hearts. I appeal to everyone throughout the world not to forget this dignity which is ours. No one has the right to take it from us.
Pope Francis describes the interior joy that comes from the recognition of sin, and the cooperation with God’s grace to transcend the worst of our own impulses. Even those of us discouraged by sin without and within can find hope. It is the Christian way.
