Jesus answered them,
Verily, verily, I say unto you, Whosoever commits sin is the servant of sin.

Cyril of Alexandria
AD 444
He lifts out of their innate unlearning these who were carnal and looking only to things corporal, He transfers them to the more spiritual and removes them to a mode of teaching wholly unpractised and unwonted, shewing them their hidden and through long ages unknown bondage; and that they falsely say, To no man have we ever been: in bondage He wisely passes by, neither does He say that to no purpose do they boast of the nobility of their forefather, in order that He may not appear to be inciting to what was not right them who were already prone and much inclined to anger, but advances to this needful matter and one which they needed verily to learn, that he is sin's bondman who doth it, as though He said thus: A compound animal, sirs, is man upon the earth, of soul that is and body, and bondage as to the flesh pertains to the flesh, but that of the soul and which takes place upon the soul, has for its mother, the barbarian, sin. The freedom then of man from bondage after the flesh the authority of the rulers will effect, but that which sets free from sin, is meet to be spoken of God Alone and will belong to none other save He. Therefore He persuades them to think reasonably and to desire real and true freedom, and thus to seek at length not the illustriousness of ancestors which nothing profits them thereto, but rather God Alone authoritative over His own Laws, the transgression whereof creates sin the foster mother of bondage to the soul. But our Lord Jesus Christ seems to be privily as yet and full veiledly convicting them of vainly thinking great things of a man and imagining that the blessed Abraham was altogether free. For His shewing generally that he who doeth sin is the bondman of sin, makes Abraham himself to have been once the bondman of sin and within its toils. For he was justified not as being himself righteous, but when he believed God then called to the freedom of being justified. And not at all as quarrelling with the fame of the righteous man do we say this, but since none among men is without trial of the darts of sin, he too who is reputed great was surely brought under the yoke of sin as it is written, There is none righteous, for all sinned and have come short of the glory of God. But the glory of God besides other things is the being utterly incapable of falling into sin, which has been reserved for Christ Alone, for He Alone has been free among the dead: for He did no sin albeit being among the dead, that is reckoned among men over whom the death of sin once had mastery.
Therefore (for I will sum up the aim of what has been said) the Lord was hinting that the blessed Abraham himself too having been once in bondage to sin, and through faith alone to Christ-ward set free, availed not to pass on to others the spiritual nobility, since neither is he master of the power of freeing others who put away the bondage of sin not by himself nor was himself on himself the bestower of freedom, but received it from Another, Christ Himself Who justifieth.
