But does not the catholic church teach that man with grace can perfectly fullfill the commandments without fault? Does not the church teach perfectionism? Also what is the context of the aquinas quote? Can we perfectly obey the commandments in this life?
Hey Vinny! Thanks for all of the great questions. You can read Aquinas’ entire commentary on Galatians
here. I don’t know Aquinas well enough to read the relevant section and to know how it relates to the rest of his theology because I’ve not read much from him.
Augustine quotes from Galatians 3:10 in
, Bk. 12, 11Against Faustus. You can read his work
On the Spirit and the Letter for a full elaboration of this thought.
Augustine’s thought is that for us to perfectly obey all of the commands of God is a possibility, but also that this will never happen. Rather, “forgetting what lies behind and straining forward to what lies ahead, I press on toward the goal for the prize of the upward call of God in Christ Jesus” (Philippians 3:13-14).
Here are a couple of quotes to illustrate the point about the possibility of perfection without there existing a real-life example of it:
“I should allow the possibility [for a man in this life to be without sin], through the grace of God and the man’s own free will; not doubting that the free will itself is ascribable to God’s grace, in other words, to the gifts of God,— not only as to its existence, but also as to its being good, that is, to its conversion to doing the commandments of God. Thus it is that God’s grace not only shows what ought to be done, but also helps to the possibility of doing what it shows. ‘What indeed have we that we have not received?’( 1 Corinthians 4:7)… I cannot doubt that God has laid no impossible command on man; and that, by God’s aid and help, nothing is impossible, by which is wrought what He commands. In this way may a man, if he pleases, be without sin by the assistance of God. If, however, I am asked the second question which I have suggested—whether there be a sinless man—I believe there is not. For I rather believe the Scripture” (
, Bk. 2, Ch. 6.7-7.8On Merit and the Forgiveness of Sins, and the Baptism of Infants).
“[M]an’s righteousness must be attributed to the operation of God, although not taking place without man’s will; and we therefore cannot deny that his perfection is possible even in this life, because all things are possible with God (cf. Mark 10:27)—both those which He accomplishes of His own sole will, and those which He appoints to be done with the cooperation with Himself of His creature’s will. Accordingly, whatever of such things He does not effect is no doubt without an example in the way of accomplished facts, although with God it possesses both in His power the cause of its possibility, and in His wisdom the reason of its unreality” (
, Ch. 5.7On the Spirit and the Letter).
Here is Augustine and the Council of Trent on the fact that we will continue to sin at least venially in this life:
“He, moreover, who says that any man, after he has received remission of sins, has ever lived in this body, or still is living, so righteously as to have no sin at all, he contradicts the Apostle John, who declares that ‘If we say we have no sin, we deceive ourselves, and the truth is not in us’ (1 John 1:8). Observe, the expression is not
we had, but ‘
we have.’ If, however, anybody contend that the apostle’s statement concerns the sin which dwells in our mortal flesh according to the defect which was caused by the will of the first man when he sinned, and concerning which the Apostle Paul enjoins us ‘not’ to ‘obey it in the lusts thereof’ (Romans 6:12)—so that he does not sin who altogether withholds his consent from this same indwelling sin, and so brings it to no evil work—either in deed, or word, or thought—although the lusting after it may be excited (which in another sense has received the name of sin, inasmuch as consenting to it would amount to sinning), but excited against our will—he certainly is drawing subtle distinctions, and should consider what relation all this bears to the Lord’s Prayer, wherein we say, ‘Forgive us our debts’ (Matthew 6:12). Now, if I judge aright, it would be unnecessary to put up such a prayer as this, if we never in the least degree consented to the lusts of the before-mentioned sin, either in a slip of the tongue, or in a wanton thought” (
, Ch. 21.44On Man’s Perfection in Righteousness).
“[D]uring this mortal life, men, how holy and just soever, at times fall into at least light and daily sins, which are also called venial, not therefore do they cease to be just. For that cry of the just, ‘Forgive us our trespasses,’ is both humble and true” (Council of Trent,
Decree on Justification, Ch. 11).
