al sin is not remitted, venial sin
exists before mortal sin: and so sometimes unbelievers have venial
together with original sin, and without mortal sins.

Obj. 2: Further, venial sin has less in common, and less connection
with mortal sin, than one mortal sin has with another. But an
unbeliever in the state of original sin, can commit one mortal sin
without committing another. Therefore he can also commit a venial sin
without committing a mortal sin.

Obj. 3: Further, it is possible to fix the time at which a child is
first able to commit an actual sin: and when the child comes to that
time, it can stay a short time at least, without committing a mortal
sin, because this happens in the worst criminals. Now it is possible
for the child to sin venially during that space of time, however
short it may be. Therefore venial sin can be in anyone with original
sin alone and without mortal sin.

_On the contrary,_ Man is punished for original sin in the children's
limbo, where there is no pain of sense as we shall state further on
(II-II, Q. 69, A. 6): whereas men are punished in hell for no other
than mortal sin. Therefore there will be no place where a man can be
punished for venial sin with no other than original sin.

_I answer that,_ It is impossible for venial sin to be in anyone with
original sin alone, and without mortal sin. The reason for this is
because before a man comes to the age of discretion, the lack of
years hinders the use of reason and excuses him from mortal sin,
wherefore, much more does it excuse him from venial sin, if he does
anything which is such generically. But when he begins to have the
use of reason, he is not entirely excused from the guilt of venial or
mortal sin. Now the first thing that occurs to a man to think about
then, is to deliberate about himself. And if he then direct himself
to the due end, he will, by means of grace, receive the remission of
original sin: whereas if he does not then direct himself to the due
end, as far as he is capable of discretion at that particular age, he
will sin mortally, through not doing that which is in his power to
do. Accordingly thenceforward there cannot be venial sin in him
without mortal, until afterwards all sin shall have been remitted to
him through grace.

Reply Obj. 1: Venial sin always precedes mortal sin not as a
necessary, but as a contingent disposition, just as work sometimes
disposes to fever, but not as heat disposes to the form of f
