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. 

Matthew 10, 32-33

Everyone who acknowledges me before others I will acknowledge before my heavenly Father. But whoever denies me before others, I will deny before my heavenly Father.

Second Peter 3, 10-16

the day of the Lord will come like a thief, and then the heavens will pass away with a mighty roar and the elements will be dissolved by fire, and the earth and everything done on it will be found out.

Since everything is to be dissolved in this way, what sort of persons ought (you) to be, conducting yourselves in holiness and devotion, waiting for and hastening the coming of the day of God, because of which the heavens will be dissolved in flames and the elements melted by fire. But according to his promise we await new heavens and a new earth 11 in which righteousness dwells.

Therefore, beloved, since you await these things, be eager to be found without spot or blemish before him, at peace. And consider the patience of our Lord as salvation, as our beloved brother Paul, according to the wisdom given to him, also wrote to you, speaking of these things as he does in all his letters. In them there are some things hard to understand that the ignorant and unstable distort to their own destruction, just as they do the other scriptures.

Luke 16, 27-31

He said, 'Then I beg you, father, send him to my father's house, for I have five brothers, so that he may warn them, lest they too come to this place of torment.' But Abraham replied, 'They have Moses and the prophets. Let them listen to them.' He said, 'Oh no, father Abraham, but if someone from the dead goes to them, they will repent.' Then Abraham said, 'If they will not listen to Moses and the prophets, neither will they be persuaded if someone should rise from the dead.'"
