Reply Obj. 1: Understanding is the fruit of faith, taken as a virtue. But we are not taking faith in this sense here, but for a kind of certitude of faith, to which man attains by the gift of understanding.
Reply Obj. 2: Faith cannot altogether precede understanding, for it would be impossible to assent by believing what is proposed to be believed, without understanding it in some way. However, the perfection of understanding follows the virtue of faith: which perfection of understanding is itself followed by a kind of certainty of faith.
Reply Obj. 3: The fruit of practical knowledge cannot consist in that very knowledge, since knowledge of that kind is known not for its own sake, but for the sake of something else. On the other hand, speculative knowledge has its fruit in its very self, which fruit is the certitude about the thing known. Hence the gift of counsel, which belongs only to practical knowledge, has no corresponding fruit of its own: while the gifts of wisdom, understanding and knowledge, which can belongs also to speculative knowledge, have but one corresponding fruit, which is certainly denoted by the name of faith. The reason why there are several fruits pertaining to the appetitive faculty, is because, as already stated, the character of end, which the word fruit implies, pertains to the appetitive rather than to the intellective part. _______________________
