When these aspects are one in the man being saved, faith has primacy and comes first, as the cause. Works follow as its consequence.
Why, then, does one Apostle speak chiefly about the importance of works, James, while the other speaks about the importance of faith, Paul?
Because the disciples of one Apostle, those of James, were directing their attention ever more toward one side, faith in Jesus, while neglecting the other, works. The disciples of the other Apostle, those of Paul, were being drawn by false teachers in the opposite direction.
They were being drawn toward the works of the Old Testament law, and away from the first side, faith in Jesus. Therefore each Apostle wished to explain to his disciples the importance of precisely that side of the matter which they neglected, or at least left without due attention.
To the Judaizing Christians of the dispersion, who carelessly dreamed of being saved by exalted Christian privileges alone, which they proudly claimed for themselves, the holy Apostle James had special reason to explain the importance of moral works.
He also had reason to explain the need for such labors of self-purification from sinful defilement as each one could undertake.
But to Christians converted from paganism, upon whom some wished to impose Jewish ritual and law, the Apostle of the Gentiles, Saint Paul, had a special reason. He had to explain the preeminent and decisive significance of faith in Jesus in justification.
He set it before the works of the Jewish ritual law, which in Christianity had become unnecessary. He also set it before works of the moral law in general, of which man has too few for justification.
Apart from the concepts and disposition of their disciples, the holy Apostles James and Paul held entirely the same view of faith and works.
For if the holy Apostle James lowers faith before works, he means only that faith which even the demons have and tremble, that is, a merely abstract and intellectual faith, cold and superficial (Jas 2:19). This is certainly not Paul’s faith.
Conversely, if the holy Apostle Paul exalts faith before works, he does not mean the faith which the Apostle James lowers. He means faith working through love (Gal 5:6), that is, faith accompanied by works of Christian love.
This is precisely the very thing for which the holy Apostle James contends.
For what works does the holy Apostle James consider necessary for salvation? They are "to visit orphans and widows in their affliction, and to keep oneself unstained from the world" (Jas 1:27).
They are also works like the deeds of Abraham and Rahab (Jas 2:21-25). That is, they are works of mercy toward neighbors and unquestioning obedience to God.
And what works does the holy Apostle Paul declare indifferent and unnecessary for salvation? They are the works of the Old Testament ritual law. "For in Christ Jesus neither circumcision nor uncircumcision avails anything" (Gal 5:6).
As for the moral duties of active piety, the strongest passages on their importance and necessity are found precisely in the Apostle Paul, for example Rom 6:1, 2, 7, 11, 18.
If the holy Apostle Paul nevertheless ascribes decisive force and significance in justification to faith and not to works, it is not because he denies their necessity for justification.
On the contrary, it is because even the most pious man does not possess as many righteous works as would be needed for his justification. Rather, we are all sinners by our fallen nature.
All our moral deficiencies are supplied only by the merits of Christ. When they are imputed and appropriated to us through faith, they also give value to our own good works.
