We must now consider the virtue itself of faith. We shall consider first faith itself, secondly those who have faith, thirdly the cause of faith, and lastly the effects of faith. Eight questions are asked concerning faith itself, i. What faith is.2. In which power of the soul it inheres.3. Whether its form is charity.4. Whether formed and unformed faith are numerically the same.5. Whether faith is a virtue.6. Whether it is a single virtue.7. How faith is related to the other virtues.8. How the certainty of faith compares with the certainty of the intellectual virtues.
