d, and
then we have the lie "in religious doctrine," or against man, and
this either with the sole intention of injuring him, and then it is
the second kind of lie, which "profits no one, and injures someone";
or with the intention of injuring one and at the same time profiting
another, and this is the third kind of lie, "which profits one, and
injures another." Of these the first is the most grievous, because
sins against God are always more grievous, as stated above (I-II, Q.
73, A. 3): and the second is more grievous than the third, since the
latter's gravity is diminished by the intention of profiting another.

After these three, which aggravate the sin of lying, we have a
fourth, which has its own measure of gravity without addition or
diminution; and this is the lie which is told "out of mere lust of
lying and deceiving." This proceeds from a habit, wherefore the
Philosopher says (Ethic. iv, 7) that "the liar, when he lies from
habit, delights in lying."

The four kinds that follow lessen the gravity of the sin of lying.
For the fifth kind is the jocose lie, which is told "with a desire to
please": and the remaining three are comprised under the officious
lie, wherein something useful to another person is intended. This
usefulness regards either external things, and then we have the sixth
kind of lie, which "profits someone in saving his money"; or his
body, and this is the seventh kind, which "saves a man from death";
or the morality of his virtue, and this is the eighth kind, which
"saves him from unlawful defilement of his body."

Now it is evident that the greater the good intended, the more is the
sin of lying diminished in gravity. Wherefore a careful consideration
of the matter will show that these various kinds of lies are
enumerated in their order of gravity: since the useful good is better
than the pleasurable good, and life of the body than money, and
virtue than the life of the body.

This suffices for the Replies to the Objections.

THIRD ARTICLE [II-II, Q. 110, Art. 3]

Whether Every Lie Is a Sin?

Objection 1: It seems that not every lie is a sin. For it is evident
that the evangelists did not sin in the writing of the Gospel. Yet
they seem to have told something false: since their accounts of the
words of Christ and of others often differ from one another:
wherefore seemingly one of them must have given an untrue account.
Therefore not every lie is a sin.
