Chapter XI: QUESTION 114 MERIT
After considering justification, which is the effect of operative A grace, we must treat of merit, which is the effect of (sanctifying) cooperative grace.1 Merit is related to sanctifying grace in the same way as operation follows being. (Cf. above Ia IIae, q. III, a. 2 c.)
There are two parts to this question.
What merit is, how divided, and what conditions it demands (a. 1-4); that is, whether man can merit anything from God, whether without grace he can merit eternal life, whether he can merit it de condigno, whether sanctifying grace is the principle of merit, principally by means of charity.
2. What is included under merit (a. 5-10); that is, whether man can merit the first grace for himself, or for another, whether he can merit reconversion for himself after a fall, whether he can merit an increase of grace for himself, final perseverance, and temporal goods.
