In due sequence we must consider the vices that are opposed to religion. First we shall consider those which agree with religion in giving worship to God; secondly, we shall treat of those vices which are manifestly contrary to religion, through showing contempt of those things that pertain to the worship of God. The former come under the head of superstition, the latter under that of irreligion. Accordingly we must consider in the first place, superstition and its parts, and afterwards irreligion and its parts.

Under the first head there are two points of inquiry:

A1 Whether superstition is a vice opposed to religion?

A2 Whether it has several parts or species?
