Again, there are some who, though mad or imbecile from birth, have, nevertheless, lucid intervals, in which they can make right use of reason. Wherefore, if then they express a desire for Baptism, they can be baptized though they be actually in a state of madness. And in this case the sacrament should be bestowed on them if there be fear of danger otherwise it is better to wait until the time when they are sane, so that they may receive the sacrament more devoutly. But if during the interval of lucidity they manifest no desire to receive Baptism, they should not be baptized while in a state of insanity.
Lastly there are others who, though not altogether sane, yet can use their reason so far as to think about their salvation, and understand the power of the sacrament. And these are to be treated the same as those who are sane, and who are baptized if they be willing, but not against their will.
Reply Obj. 1: Imbeciles who never had, and have not now, the use of reason, are baptized, according to the Church's intention, just as according to the Church's ritual, they believe and repent; as we have stated above of children (A. 9, ad Obj.). But those who have had the use of reason at some time, or have now, are baptized according to their own intention, which they have now, or had when they were sane.
Reply Obj. 2: Madmen and imbeciles lack the use of reason accidentally, i.e. through some impediment in a bodily organ; but not like irrational animals through want of a rational soul. Consequently the comparison does not hold.
Reply Obj. 3: A person should not be baptized while asleep, except he be threatened with the danger of death. In which case he should be baptized, if previously he has manifested a desire to receive Baptism, as we have stated in reference to imbeciles: thus Augustine relates of his friend that "he was baptized while unconscious," because he was in danger of death (Confess. iv). _______________________
QUESTION 69
OF THE EFFECTS OF BAPTISM
(In Ten Articles)
We must now consider the effects of Baptism, concerning which there are ten points of inquiry:
(1) Whether all sins are taken away by Baptism?
(2) Whether man is freed from all punishment by Baptism?
