[¶0] OF UNBELIEF IN GENERAL (TWELVE ARTICLES)

[¶1] 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.

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

[¶3] Under the first head there are twelve points of inquiry:

[¶4] (1) Whether unbelief is a sin?

[¶5] (2) What is its subject?

[¶6] (3) Whether it is the greatest of sins?

[¶7] (4) Whether every action of unbelievers is a sin?

[¶8] (5) Of the species of unbelief;

[¶9] (6) Of their comparison, one with another;

[¶10] (7) Whether we ought to dispute about faith with unbelievers?

[¶11] (8) Whether they ought to be compelled to the faith?

[¶12] (9) Whether we ought to have communications with them?

[¶13] (10) Whether unbelievers can have authority over Christians?

[¶14] (11) Whether the rites of unbelievers should be tolerated?

[¶15] (12) Whether the children of unbelievers are to be baptized against their parents' will?
