Do not make the mistake of thinking that you can ever be outside your brother's sin.
you cannot stand outside your brother's condition and judge it cleanly. Judgment itself implicates you in what you're judging.
He will hear plainly that the calls to war he heard before are really calls to peace. ²He will perceive that where he gave attack is but another altar where he can, with equal ease and far more happiness, bestow forgiveness. ³And he will reinterpret all temptation as just another chance to bring him joy. ⁴How can a misperception be a sin? ⁵Let all your brother’s errors be to you nothing except a chance for you to see the workings of the Helper given you to see the world He made instead of yours. - [CE T-25.III.7]
To witness sin and yet forgive it is a paradox which reason cannot see. ²For it maintains what has been done to you deserves no pardon, and by giving it, you grant your brother mercy but retain the proof he is not really innocent. ³The sick remain accusers. ⁴They cannot forgive their brothers and themselves as well, for no one in whom true forgiveness reigns can suffer. ⁵He holds not the proof of sin before his brother’s eyes, and thus he must have overlooked it and removed it from his own. ⁶Forgiveness cannot be for one and not the other. ⁷Who forgives is healed. ⁸And in his healing lies the proof that he has truly pardoned, and retains no trace of condemnation that he still would hold against himself or any living thing. - [CE T-27.II.3]
While you believe that your reality or your brother’s is bounded by a body, you will believe in sin. ²While you believe that bodies can unite, you will find guilt attractive and believe that sin is precious. ³For the belief that bodies limit the mind leads to a perception of the world in which the proof of separation seems to be everywhere. ⁴And God and His creation seem to be split apart and overthrown. ⁵For sin would prove what God created holy could not prevail against it, nor remain itself before its power. - [CE T-19.III.10]
Long ago we said consider not the means by which salvation is attained or how to reach it, but do consider, and consider well, whether it be your wish that you might see your brother sinless. ²To specialness the answer must be no. ³A sinless brother is its enemy, while sin, if it were possible, would be its friend. ⁴Your brother’s “sins” would justify itself and give it meaning that the truth denies. ⁵All that is real proclaims his sinlessness. ⁶All that is false proclaims his sins as real. ⁷If he is sinful, then is your reality not real, but just a dream of specialness which lasts an instant, crumbling into dust. - [CE T-24.IV.5]
