Certain sins, moreover, constitute by their very object a direct assault on one's neighbour. Such sins in particular are known as social sins. Social sin is every sin committed against the justice due in relations between individuals, between the individual and the community, and also between the community and the individual. Social too is every sin against the rights of the human person, starting with the right to life, including that of life in the womb, and every sin against the physical integrity of the individual; every sin against the freedom of others, especially against the supreme freedom to believe in God and worship him; and every sin against the dignity and honour of one's neighbour. Every sin against the common good and its demands, in the whole broad area of rights and duties of citizens, is also social sin. In the end, social sin is that sin that “refers to the relationships between the various human communities. These relationships are not always in accordance with the plan of God, who intends that there be justice in the world and freedom and peace between individuals, groups and peoples” John Paul II, Apostolic Exhortation Reconciliatio et Paenitentia, 16: AAS — Acta Apostolicae Sedis (official gazette of the Holy See)Volume 77 (1985) at vatican.va — scanned PDF (1985), 216..
