Encyclical Letter Spe Salvi Nº 49, Author: Benedict XVI

Human life is a journey. Towards what destination? How do we find the way? Life is like a voyage on the sea of history, often dark and stormy, a voyage in which we watch for the stars that indicate the route. The true stars of our life are the people who have lived good lives. They are lights of hope. Certainly, Jesus Christ is the true light, the sun that has risen above all the shadows of history. But to reach him we also need lights close by—people who shine with his light and so guide us along our way.

Apostolic Exhortation Reconciliation and Penance Nº 16, Author: John Paul II OF JOHN PAUL II

each individual's sin in some way affects others. This is the other aspect of that solidarity which on the religious level is developed in the profound and magnificent mystery of the communion of saints, thanks to which it has been possible to say that "every soul that rises above itself, raises up the world." (The expression from the French writer Elizabeth Leseur, Journal et Pensees de Chaque Jour, Paris 1918, p. 31.)To this law of ascent there unfortunately corresponds the law of descent. Consequently one can speak of a communion of sin, whereby a soul that lowers itself through sin drags down with itself the church and, in some way, the whole world. In other words, there is no sin, not even the most intimate and secret one, the most strictly individual one, that exclusively concerns the person committing it. With greater or lesser violence, with greater or lesser harm, every sin has repercussions on the entire ecclesial body and the whole human family.
