- Is there a variety of sins?
There are a great many kinds of sins. They can be distinguished according to their object or according to the virtues or commandments which they violate. They can directly concern God, neighbor, or ourselves. They can also be divided into sins of thought, of word, of deed, or of omission.
- How are sins distinguished according to their gravity?
A distinction is made between mortal and venial sin.
- When does one commit a mortal sin?
One commits a mortal sin when there are simultaneously present: grave matter, full knowledge, and deliberate consent. This sin destroys charity in us, deprives us of sanctifying grace, and, if unrepented, leads us to the eternal death of hell. It can be forgiven in the ordinary way by means of the sacraments of Baptism and of Penance or Reconciliation.
- When does one commit a venial sin?
One commits a venial sin, which is essentially different from a mortal sin, when the matter involved is less serious or, even if it is grave, when full knowledge or complete consent are absent. Venial sin does not break the covenant with God but it weakens charity and manifests a disordered affection for created goods. It impedes the progress of a soul in the exercise of the virtues and in the practice of moral good. It merits temporal punishment which purifies.
