In due sequence we must consider the contrary vices: first, unbelief, which is contrary to faith; secondly, blasphemy, which is opposed to confession of faith; thirdly, ignorance and dulness of mind, which are contrary to knowledge and understanding.

As to the first, we must consider (1) unbelief in general; (2) heresy; (3) apostasy from the faith.

Under the first head there are twelve points of inquiry:

A[1] Whether unbelief is a sin?

A[2] What is its subject?

A[3] Whether it is the greatest of sins?

A[4] Whether every action of unbelievers is a sin?

A[5] Of the species of unbelief;

A[6] Of their comparison, one with another;

A[7] Whether we ought to dispute about faith with unbelievers?

A[8] Whether they ought to be compelled to the faith?

A[9] Whether we ought to have communications with them?

A[10] Whether unbelievers can have authority over Christians?

A[11] Whether the rites of unbelievers should be tolerated?

A[12] Whether the children of unbelievers are to be baptized against their parents'will?
