One of the hallmarks of Satan's workings is to assail the very atonement in which Christ died for sinners.
Heresy:
A “slain Christ has no meaning.”
A Course in Miracles, Text, p. 425
“The journey to the cross should be the last ‘useless journey.’”
A Course in Miracles, p. 52
“The Atonement is the final lesson he [man] need learn, for it teaches him that, never having sinned, he has no need of salvation.”
A Course in Miracles, p. 237
"The full awareness of the Atonement, then, is the recognition that the separation never occurred."
A Course in Miracles, Text, p. 98
“Do not make the pathetic error of ‘clinging to the old rugged cross’. The only message of the crucifixion is that you can overcome the cross. Until then you are free to crucify yourself as often as you choose. This is not the Gospel I intended to offer you.”
A Course in Miracles, Text, p. 52

Ephesians 1:7

who gave Himself for our sins, that He might deliver us from this present evil age..."
Galatians 1:3-4
* * "Anyone who has rejected Moses' law dies without mercy on the testimony of two or three witnesses. Of how much worse punishment, do you suppose, will he be thought worthy who has trampled the Son of God underfoot, counted the blood of the covenant by which he was sanctified a common thing, and insulted the Spirit of grace?" * *
Hebrews 10:28-29
