"Only the mind AND body need atonement."
So long as the effects of sin remain, there is evidence which proves and teaches that your brother DID COMMIT A SIN, and therefore is NOT exonerated. Only by healing your body and removing the consequences of attack can he be innocent. Your healed body teaches him HIS innocence AND heals HIS body, and thus he is healed along with you. Miracles heal your body AND your brother's body.
Healthy mind, healthy body. Sick mind, sick body. There are no exceptions.
If your brother attacks you, you MUST heal your body and demonstrate HE DID NOT SIN, and is therefore innocent.
**THIS IS REAL FORGIVENESS**
Here are excerpts from the section of A Course in Miracles titled "The Fear of Healing."
"For accusation is a bar to love, and damaged bodies ARE accusers."
"Who has been injured BY his brother, and could love and trust him still? He HAS attacked, and will attack again. Protect him not, because your damaged body shows that you must be protected FROM him."
"He may be PITIED for his guilt, but NOT exonerated."
"The unhealed CANNOT pardon. For they are the witnesses that pardon is unfair. They would retain the CONSEQUENCES of the guilt they overlook. Yet no-one CAN forgive a sin which he believes is real. And what has consequences MUST be real, because what it has DONE is there to see."
"forgiveness does not first ESTABLISH sin, and THEN forgive it. Who can say and MEAN, "My brother, you have injured me, and yet, because I am the BETTER of the two, I pardon you my hurt."
"To witness sin and yet forgive it is a paradox which reason cannot see."
"you grant your brother mercy, but retain the proof he is not REALLY innocent. The sick remain accusers."
"For no-one in whom true forgiveness reigns CAN suffer. He holds not the proof of sin before his brother's eyes. And thus he MUST have overlooked it, and removed it from his own."
"Who forgives IS healed. And 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."
"Forgiveness is not real UNLESS it brings a healing to your brother AND yourself. YOU must attest his sins had no effect on YOU, to demonstrate they were not real. How else COULD he be guiltless? And how COULD his innocence be justified UNLESS his sins have no effect to WARRANT guilt?"
"Sins are beyond forgiveness just BECAUSE they would entail effects which CANNOT be undone and overlooked entirely. In their UNDOING lies the proof that they were merely errors."
"LET yourself be healed, that you may be forgiving, offering salvation to your brother AND yourself. A broken body shows the mind has NOT been healed. A miracle of healing proves that separation is WITHOUT effect."
"What you would prove to him you will believe. The power of witness COMES from your belief. And everything you say or do or think but testifies to what you teach to him."
"Your body can be means to teach that it has never suffered pain because of him. And in its healing can it offer him mute testimony to his innocence. It is THIS testimony that can speak with power greater than a thousand tongues. For here is his forgiveness PROVED to him."
"So does your healing show your mind is healed, and has forgiven what he did NOT do. And so is HE convinced his innocence was never lost, and healed along with you."
"Thus does the miracle undo all things the world attests can never BE undone. And hopelessness and death MUST disappear before the ancient clarion call of life. This call has power FAR beyond the weak and miserable cry of death and guilt."
"And this you learn when you but wish to show your brother that you had no hurt of him. He thinks your blood is on his hands, and so he stands condemned. But it is given you to SHOW him, by your healing, that his guilt is but the fabric of a senseless dream."
"How just are miracles! For they bestow an equal gift of full deliverance from guilt upon your brother AND yourself. YOUR healing saves HIM pain, as well as you. And YOU are healed BECAUSE you wished him well."
"And love would prove ALL suffering is but a vain imagining, a foolish wish, with NO effects. Your health is a result of your desire to see your brother with no blood upon his hands, nor guilt upon his heart made heavy with the proof of sin."
"The Holy Spirit knows YOUR healing is the witness UNTO his, and CANNOT be apart from him at all. As long as he consents to suffer, YOU will be unhealed."
"But you can show him his suffering is purposeless and wholly without cause. Show him YOUR healing, and he will consent no more to suffer. For his innocence HAS BEEN established in your sight AND his. And laughter will REPLACE your sighs BECAUSE God's Son remembered that he IS God's Son."
-- See also this passage from "The Picture of Crucifixion" which precedes "the fear of healing"...
"Now in the hands made gentle by His touch, the Holy Spirit lays a picture of a DIFFERENT you. It is a picture of a body still, for what you REALLY are can not be seen nor pictured. But THIS one has NOT been used for purpose of attack, and therefore never suffered pain at all. IT witnesses to the eternal truth that you can not BE hurt, and points BEYOND itself to both YOUR innocence and HIS.
Show THIS unto your brother, who will see that every scar is healed, and every tear is wiped away in laughter and in love. And he will look on his forgiveness there, and with healed eyes will look BEYOND it, to the innocence that he beholds in you. Here is the proof that he has NEVER sinned; that NOTHING that his madness bid him do was ever done, or ever had effects of any kind. That NO reproach he laid upon his heart was EVER justified, and NO attack can touch him with the poisoned sting of fear. Attest his innocence and NOT his guilt. YOUR healing is his comfort and HIS health. BECAUSE it proves illusions were not true."
"Now is the body healed by miracles."
"The mind must be stronger than the body. Every miracle demonstrates this."
