My little children, these things write I unto you, that you sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:
Read Chapter 2
Augustine of Hippo
AD 430
And lest haply he should seem to have given impunity for sins, in that he said, He is faithful and just to cleanse us from all iniquity; and men henceforth should say to themselves, Let us sin, let us do securely what we will, Christ purges us, is faithful and just, purges us from all iniquity: He takes from you an evil security, and puts in an useful fear. To your own hurt you would be secure; you must be solicitous. For He is faithful and just to forgive us our sins, provided you always displease yourself, and be changing until you be perfected.
My little children, these things write I unto you, that ye sin not. At the end of the last chapter it was said that all who were grown up had sinned, either mortally as heathens, or venially as Christians. But he now exhorts them one by one to be most watchful against the sins they committed as heathens, and to abstain as far as they could from venial sins. For though it be impossible to avoid them collectively, yet it is possible to avoid them one by one, especially such as are committed not by surprise, but with previous consideration, and deliberately.
But if any man sin, we have an Advocate. This anticipates the objection, what then will he do, who through human weakness has fallen into some unusual and shameful sin? He answers, he should not despair, or be cast down, because we have Christ as our advocate with our most loving Father, Christ who by presenting His death and sufferings which He underwent for us, will easily obtain our pardon, if we are truly penitent, for God is mos...
Sed dicet aliquis, says St. Augustine on this place, ergo sancti non petunt pro nobis. Ergo episcopi et præpositi non petunt pro populo; sed attendite scripturas Ver. 5. Perfecta est, teteleiotai. This must only be understood of charity so perfected as to be true charity, but not a perfect degree of charity.
That you may not sin, or not lose the grace of God by any considerable sin.
But if any man sin, we have an advocate with the Father, Jesus Christ, the eternal Son of the Father, who being made man to redeem us from sin, is our great Advocate, our chief Mediator, and only Redeemer, by whose merits and grace we have been reconciled, after we had lost and forfeited the grace and favour of God by our offences. He is the only propitiation for the sins of the whole world; for, as St. Paul says, (Hebrews x. 14.) Christ, for one oblation on the cross, hath perfected for ever them that are sanctified. All remission of sins, all sanctification, is derived from the merits and satisfaction of our Redeemer, Jesus Christ; not but that the Angels and saints in heaven, and virtuous persons upon earth, when they pray to God for us, may be called advocates, mediators, and intercessors (though not redeemers) in a different sense, and in an inferior manner, without any injury, but on the contrary with an...
Wherefore we have need of the dew of God, that we be not consumed by fire, nor be rendered unfruitful, and that where we have an accuser there we may have also an Advocate,
All the more fully: "Little children, these things have I written to you, lest ye sin; and if ye shall have sinned, an Advocate we have with God the Father, Jesus Christ the righteous; and, He is the propitiation for our sins."
