Envy

Envy is sorrow or sadness over another’s good,because that good is regarded as something withheld or taken awayfrom the envious person’s excellence or reputation.

Envy is a sin; it grieves over what charity finds capable of causing joy; it is a spiritual disorder.

Envy in its kind (or genus) is a mortal sin, for it isin conflict with the precept of charity. But in the envious person the sin of envy is mortal only when it is committed with full knowledge and full consent.

Envy is a fruitful source of other sins, and therefore it is listed with the capital sins.
