Question 4 — The Virtue Itself of Faith

We must now consider the virtue itself of faith, and, in the first place, faith itself; second, those who have faith; third, the cause of faith; fourth, its effects.

Under the first head there are eight points of inquiry:

(1) What is faith?

• (2) In what power of the soul does it reside?
• (3) Whether its form is charity?
• (4) Whether living (formata) faith and lifeless (informis) faith are one identically?
• (5) Whether faith is a virtue?
• (6) Whether it is one virtue?
• (7) Of its relation to the other virtues;
• (8) Of its certitude as compared with the certitude of the intellectual virtues.
