Being justified freely by his grace through the redemption that is in Christ Jesus: Being justified freely by his grace - So far from being able to attain the glory of God by their obedience, they are all guilty: and, to be saved, must be freely pardoned by God's grace; which is shown to them who believe, through the redemption, απολυτρωσεως, the ransom price, which is in the sacrifice of Christ Jesus. The original is compounded of απο, from, and λυτροω, I redeem, and properly means the price laid down for the redemption of a captive. Comprehendit haec Christi απολυτρωσις, quicquid is docuit, fecit et passus est, eo consilio, ut homines malis liberati, praecipue peccato, malorum fonte immunes, veram felicitatem adipiscerentur. - Rosenmuller. This redemption of Christ comprehends whatsoever he taught, did, or suffered, in order to free men from evil; especially to free them from sin, the source of evils; that they might attain true felicity. And that it here means the liberation purchased by the blood-shedding of Christ, is evident from Ephesians 1:7 : We have Redemption, απολυτρωσιν δια του αιματος αυτου, Through His Blood, the forgiveness of sins, according to the riches of his grace. See also Colossians 1:14, where the same words are found.
Λυτρα according to Suidas, is μισθος, η τα παρεχομενα υπερ ελευθεριας, επι τω λυτρωσασθαι βαρβαρων δουλειας A reward; or the price given to be redeemed from the slavery of the barbarians. Schleusner, under the word απολυτρωσις, says, Negari quidem non potest, hanc vocem proprie notare redemptionem ejus, qui captivus detinetur, sive bello, sive alio captus sit modo, quae fit per pretti solutionem; quo sensu verbum απολυτροω legitur haud raro in Scripp. Graecis. No man certainly can deny that this word properly means the redemption of a captive, (whether he may have been taken in war or in any other way), which is procured by the payment of a price. That the word also means any deliverance, even where no price is paid down, nobody will dispute; but that it means redemption by a price laid down, and the redemption of the soul by the price of the death of Christ, the above scriptures sufficiently prove.
