TICLE [II-II, Q. 33, Art. 5]

Whether a Sinner Ought to Reprove a Wrongdoer?

Objection 1: It would seem that a sinner ought to reprove a
wrongdoer. For no man is excused from obeying a precept by having
committed a sin. But fraternal correction is a matter of precept, as
stated above (A. 2). Therefore it seems that a man ought not to
forbear from such like correction for the reason that he has
committed a sin.

Obj. 2: Further, spiritual almsdeeds are of more account than
corporal almsdeeds. Now one who is in sin ought not to abstain from
administering corporal alms. Much less therefore ought he, on account
of a previous sin, to refrain from correcting wrongdoers.

Obj. 3: Further, it is written (1 John 1:8): "If we say that we have
no sin, we deceive ourselves." Therefore if, on account of a sin, a
man is hindered from reproving his brother, there will be none to
reprove the wrongdoer. But the latter proposition is unreasonable:
therefore the former is also.

_On the contrary,_ Isidore says (De Summo Bono iii, 32): "He that is
subject to vice should not correct the vices of others." Again it is
written (Rom. 2:1): "Wherein thou judgest another, thou condemnest
thyself. For thou dost the same things which thou judgest."

_I answer that,_ As stated above (A. 3, ad 2), to correct a wrongdoer
belongs to a man, in so far as his reason is gifted with right
judgment. Now sin, as stated above (I-II, Q. 85, AA. 1, 2), does not
destroy the good of nature so as to deprive the sinner's reason of
all right judgment, and in this respect he may be competent to find
fault with others for committing sin. Nevertheless a previous sin
proves somewhat of a hindrance to this correction, for three reasons.
First because this previous sin renders a man unworthy to rebuke
another; and especially is he unworthy to correct another for a
lesser sin, if he himself has committed a greater. Hence Jerome says
on the words, "Why seest thou the mote?" etc. (Matt. 7:3): "He is
speaking of those who, while they are themselves guilty of mortal
sin, have no patience with the lesser sins of their brethren."

Secondly, such like correction becomes unseemly, on account of the
scandal which ensues therefrom, if the corrector's sin be well known,
because it would seem that he corrects, not out of charity, but more
for the sake of ostentation. Hence the words of Matt. 7:4, "How
sayest thou to thy brother?" etc. are expounded by Chrysostom [*Hom.
