Hypocrisy
Sinfulness of Hypocrisy
Sinfulness of Hypocrisy.—(a) Hypocrisy in its strictest sense is the simulation of one who wishes to seem but not to be virtuous. This sin is mortal, since it cares nothing for virtue, and its external pretense is but a mockery. It is this hypocrisy that is so scathingly denounced in Scripture.
(b) Hypocrisy in a less strict sense is the simulation of one who is in mortal sin, but wishes for some reason to appear virtuous or to lead a double life. The sin is mortal or venial according to the motive; for example, to act the hypocrite in order to seduce another is a mortal sin, though, if the motive is only vanity, the sin is venial. It should be noted that it is not hypocrisy for a just cause to conceal one’s sin by dissimulation; indeed, Isaias severely blames those who scandalize others by flaunting their wickedness before the public (Is, iii. 9).
(c) Hypocrisy in the widest sense assumes the appearance of a high degree of sanctity above that requisite for salvation, as when a person of ordinary goodness tries to gain the reputation of miracle-worker, or to pass as one better than others in faith, zeal, humility, etc. This sin is not mortal in itself, but it may become mortal on account of some motive, some means, or some other circumstance. There is no hypocrisy at all, however, in showing oneself for the virtue one really has; on the contrary, he lies, who being good pretends that he is not good, or who being free of a vice pretends that he is guilty of it.
