/summa/TP/TPIII/TP_Q71:
We have now to consider the preparations that accompany Baptism: concerning which there are four points of inquiry:
(1) Whether catechism should precede Baptism?
(2) Whether exorcism should precede Baptism?
(3) Whether what is done in catechizing and exorcizing, effects anything, or is a mere sign?
(4) Whether those who are to be baptized should be catechized or exorcized by priests?
