If we allow or participate in the sin of another, we
share that sin and its consequences.
As the Catechism of the Catholic Church (CCC) teaches,
1868 Sin is a personal act. Moreover, we have a responsibility for the sins committed by others when we cooperate in them:
—by participating directly and voluntarily in them;
—by ordering, advising, praising, or approving them;
—by not disclosing or not hindering them when we have an obligation to do so;
—by protecting evil-doers (no. 1868, original emphasis).
2284 Scandal is an attitude or behavior which leads another to do evil. The person who gives scandal becomes his neighbor’s tempter. He damages virtue and integrity; he may even draw his brother into spiritual death. Scandal is a grave offense if by deed or omission another is deliberately led into a grave offense.
2287 Anyone who uses the power at his disposal in such a way that it leads others to do wrong becomes guilty of scandal and responsible for the evil that he has directly or indirectly encouraged. ‘Temptations to sin are sure to come; but woe to him by whom they come!’ (Lk. 17:1)
Fornication and
adultery are
mortal sins. Those who persist in these sins endanger their salvation. They violate the :bible1:
Sixth Commandment (CCC, nos. 2331-2400). Living together before marriage is fornication
(CCC, no. 2353). Subsequent marriage of the couple does not blot out the sins they already committed, nor does the wedding itself necessarily change their attitudes or habits toward chastity and purity.
Divorce and remarriage is an act of adultery, regardless of whether the “spouses” are Catholic or not (cf. Mark 10:10-12; CCC, no. 2384). For a Catholic who marries outside the Church, the Church does not recognize the marriage, and the union is considered adulterous
(Code of Canon Law, canon 1108). [1] No one should promote fornication or
adultery.
