We have now to consider things that are preparatory to Baptism: and (1) that which preceded Baptism, viz. Circumcision, (2) those which accompany Baptism, viz. Catechism and Exorcism.
Concerning the first there are four points of inquiry:
(1) Whether circumcision was a preparation for, and a figure of, Baptism?
(2) Its institution;
(3) Its rite;
(4) Its effect.
