We must now consider the act of faith, and (1) the internal act; (2) the external act.

Under the first head there are ten points of inquiry:

A[1] What is "to believe," which is the internal act of faith?

A[2] In how many ways is it expressed?

A[3] Whether it is necessary for salvation to believe in anything above natural reason?

A[4] Whether it is necessary to believe those things that are attainable by natural reason?

A[5] Whether it is necessary for salvation to believe certain things explicitly?

A[6] Whether all are equally bound to explicit faith?

A[7] Whether explicit faith in Christ is always necessary for salvation?

A[8] Whether it is necessary for salvation to believe in the Trinity explicitly?

A[9] Whether the act of faith is meritorious?

A[10] Whether human reason diminishes the merit of faith?
