Whether man can merit everlasting life without grace?
Objections
❌ Objection 1 : It would seem that man can merit everlasting life without grace. For Our Lord says (Mt. 19:17): "If thou wilt enter into life, keep the commandments"; from which it would seem that to enter into everlasting life rests with man's will. But what rests with our will, we can do of ourselves. Hence it seems that man can merit everlasting life of himself.
❌ Objection 2 : Further, eternal life is the wage of reward bestowed by God on men, according to Mt. 5:12: "Your reward is very great in heaven." But wage or reward is meted by God to everyone according to his works, according to Ps. 61:12: "Thou wilt render to every man according to his works." Hence, since man is master of his works, it seems that it is within his power to reach everlasting life.
❌ Objection 3 : Further, everlasting life is the last end of human life. Now every natural thing by its natural endowments can attain its end. Much more, therefore, may man attain to life everlasting by his natural endowments, without grace.
