This view is strengthened by the further teaching of the Fathers that supernatural grace was as indispensable to the angels in their state of probation (in which they were free from concupiscence) and to our first parents in Paradise (gifted as they were with the _donum integritatis_), as it is to fallen man; the only difference being that in the case of the latter, grace has the additional object of curing the infirmities and overcoming the difficulties arising from concupiscence. In regard to the angels St. Augustine says; “And who made this will but He who created them with a good will, that is to say with a chaste love by which they should cleave to Him, in one and the same act creating their nature and endowing it with grace?... We must therefore acknowledge, with the praise due to the Creator, that not only of holy men, but also of the holy angels, it can be said that ‘the love of God is shed abroad in their hearts by the Holy Ghost, who is given unto them.’ ”(281) Equally convincing is the argument that Adam in Paradise was unable to perform any salutary acts without divine grace. “Just as it is in man’s power to die whenever he will,” says St. Augustine, “... but the mere will cannot preserve life in the absence of food and the other means of life; so man in Paradise was able of his mere will, simply by abandoning righteousness, to destroy himself; but to have led a life of righteousness would have been too much for his will, unless it had been sustained by the power of Him who made him.”(282) This is also the teaching of the Second Council of Orange (A. D. 529): “Even if human nature remained in the state of integrity, in which it was constituted, it would in no wise save itself without the help of its Creator. If it was unable, without the grace of God, to keep what it had received, how should it be able without the grace of God to regain what it has lost?”(283) c) The theological argument for the metaphysical necessity of grace is based on the essentially supernatural character of all salutary acts. α) St. Thomas formulates it as follows: “Eternal life is an end transcending the proportion of human nature, ... and therefore man, by nature, can perform no meritorious works proportioned to eternal life, but requires for this purpose a higher power,—the power of grace. Consequently, man cannot merit eternal life without grace. He is, however, able to perform acts productive of some good connatural to man, such as tilling the soil, drinking, eating, acts of friendship, etc.”(284) For the reason here indicated it is as impossible for man to perform salutary acts without grace as it would be to work miracles without that divine assistance which transcends the powers of nature.(285)
