EIGHTH ARTICLE [III, Q. 84, Art. 8]

Whether Penance Should Last Till the End of Life?

Objection 1: It would seem that Penance should not last till the end

of life. Because Penance is ordained for the blotting out of sin. Now

the penitent receives forgiveness of his sins at once, according to

Ezech. 18:21: "If the wicked do penance for all his sins which he

hath committed . . . he shall live and shall not die." Therefore

there is no need for Penance to be further prolonged.

Obj. 2: Further, Penance belongs to the state of beginners. But man

ought to advance from that state to the state of the proficient, and,

from this, on to the state of the perfect. Therefore man need not do

Penance till the end of his life.

Obj. 3: Further, man is bound to observe the laws of the Church in

this as in the other sacraments. But the duration of repentance is

fixed by the canons, so that, to wit, for such and such a sin one is

bound to do penance for so many years. Therefore it seems that

Penance should not be prolonged till the end of life.

_On the contrary,_ Augustine says in his book, _De Poenitentia_ [*De

vera et falsa Poenitentia, the authorship of which is unknown]: "What

remains for us to do, save to sorrow ever in this life? For when

sorrow ceases, repentance fails; and if repentance fails, what

becomes of pardon?"

_I answer that,_ Penance is twofold, internal and external. Internal

penance is that whereby one grieves for a sin one has committed, and

this penance should last until the end of life. Because man should

always be displeased at having sinned, for if he were to be pleased

thereat, he would for this very reason fall into sin and lose the

fruit of pardon. Now displeasure causes sorrow in one who is

susceptible to sorrow, as man is in this life; but after this life

the saints are not susceptible to sorrow, wherefore they will be

displeased at, without sorrowing for, their past sins, according to

Isa. 65:16. "The former distresses are forgotten."

External penance is that whereby a man shows external signs of

sorrow, confesses his sins verbally to the priest who absolves him,

and makes satisfaction for his sins according to the judgment of the

priest. Such penance need not last until the end of life, but only

for a fixed time according to the measure of the sin.

Reply Obj. 1: True penance not only removes past sins, but also

preserves man from future sins. Consequently, although a man receives

forgiveness of past sins in the first instant of his true penance,

nevertheless he must persevere in his penance, lest he fall again

into sin.

Reply Obj. 2: To do penance both internal and external belongs to the

state of beginners, of those, to wit, who are making a fresh start

from the state of sin. But there is room for internal penance even in

the proficient and the perfect, according to Ps. 83:7: "In his heart

he hath disposed to ascend by steps, in the vale of tears." Wherefore

Paul says (1 Cor. 15:9): "I . . . am not worthy to be called an

apostle because I persecuted the Church of God."

Reply Obj. 3: These durations of time are fixed for penitents as

regards the exercise of external penance.
