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.

A1 Whether circumcision was a preparation for, and a figure of, Baptism?

A2 Its institution;

A3 Its rite;

A4 Its effect.
