For in Jesus Christ neither circumcision avails anything, nor uncircumcision; but faith which works by love.

For in Christ Jesus, &c. In the Church neither Judaism nor Gentilism is of any avail towards the life of holiness and bliss. Judaism is depreciated here by being classed with Gentilism. The only effectual power is faith—not a faith that is barren of works, but that which worketh by love, and manifests itself in works of charity. Such a faith was that of the Magdalene when she bathed Christ"s feet with her tears. But a faith which shows no works of charity Isaiah , as Anselm says, the faith, not of Christians, but of devils. The Protestants who attribute justification to faith alone should remark this. Our brother Campian, the martyr of England, when in prison and disputing with the Lutherans, refuted them by this syllogism: That faith which avails before God to justify Isaiah , as the Apostle testifies, a faith which worketh by love; therefore it is obvious that it is united to charity. But the justifying faith of the Lutherans is not a faith that worketh by love, for it Isaiah , they say, alone, and hence is not accompanied by charity; therefore, the faith which they lay down is not a faith that justifies before God. To say, then, that faith is alone, and that such a faith justifies, is a contradiction. If faith is to justify, it must be accompanied by charity; and when it is so accompanied it is no longer alone.
It should be remarked that faith does not work by means of charity as an efficient cause works by its instrument, but in the way that beat in the form of fire kindles wood. Faith through charity does good works, by performing acts of charity towards God and our neighbour, and by determining, the nature of acts of other virtues. For charity is not an essential but an accidental form, which gives to faith and all good works their life, validity, and merit, in due relation to their ultimate end. It gives to faith and all other virtues (1.) their character of virtue. Where charity Isaiah , vice cannot be; but virtue reigns enthroned as queen by charity, which ennobles also every Acts , so that the man under its sway may be called absolutely virtuous, righteous, and holy. (2.) Charity also gives the acts of virtue their dignity and power of winning merit, for it makes a man the friend and son of God, and so dignifies his works that God promises them eternal rewards. (3.) Charity also determines the relation of the various acts of virtue to their ultimate end, inasmuch as it directs to God the whole Prayer of Manasseh , and all that he does, says, or thinks. So S. Thomas.
The Greek word for worketh denotes internal efficacy, hidden power. Faith informed by charity, having charity as its soul, by its inward and spiritual power, worketh the living works of virtue.
