How are sins distinguished ?
Sins can be distinguished according to their objects, as can every human act. Sins can be distinguished according to the virtues they oppose, by excess or defect, or by commandments they violate. Sins can be classed according to the person they concern, whether they concern God, neighbour or oneself. Sins can be divided into spiritual and carnal sins. Sins can be divided as sins in thought, word, deed or omission.
