Thus not one sin remains upon us for which we ourselves would have to pay.
But this is not all. The bonds of slavery are removed from a ransomed slave, and he receives freedom to act for himself. We were in the bonds of slavery to sin.
Having ransomed us, the Savior breaks these bonds, "that we should no longer serve sin" (Rom 6:6). We receive freedom to act for ourselves as our nature, created according to the image of God, requires.
We no longer act according to the impulse of sin, the intruding tyrant. This is full redemption, or deliverance.
"He did not redeem us from one iniquity and not another, but from every iniquity. Let us therefore honor our redemption," by being ashamed to darken it with any sin (Blessed Theophylact).
"And to purify for Himself a chosen people." "Purify," καθαριση, is like clearing debts by payment.
Or, if applied to the state of redeemed slaves, who are received unkempt, filthy, wounded, and in rags, "purify" means to wash away every sinful impurity.
It means to heal every wound of the passions and to clothe them in the beautiful garments of the virtues.
"A chosen people," λαον περιουσιον. Περιουσιος means excellent, distinguished, set apart from others, and having nothing in common with them. See St. Chrysostom and Blessed Theophylact.
Or it means one's own, turned into one's own possession by force of redemption and appointed to works according to one's spirit.
"It is taken metaphorically from servants who attend to the property, περι την ουσιαν, and possession of their master" (Blessed Theophylact).
Thus the Savior gave Himself to ransom us, to purify us from every impurity and wound, and to make us excellent. Then He appoints us to works according to His own Spirit.
How does He do this? "By the laver of divine baptism and the doing of His divine and purifying commandments" (Blessed Theophylact).
"Christ Jesus, our great God and Savior, having redeemed us by His blood, made us for Himself a special Christian people. This people can be special only when it is zealous for good works" (Blessed Jerome).
"Zealous for good works" means "ardently striving after virtue, showing zeal for all good works, and displaying fervent imitation of the Savior Himself" (Blessed Theophylact).
"He does not simply require works, but that we be zealots, that is, doing good works with great zeal and proper diligence.
To deliver those burdened by many evils and heal those incurably sick was the work of His love for mankind. What follows is the work of both us and Him" (St. Chrysostom).
