resurrection

Christian: The rising of Jesus’ body, which proved that he was divine. The rising of all believers at the end of time.

ACIM:

The rising of the mind, and of the entire Sonship, from the ego’s dream of death to the awareness of eternal life, from insanity to perfectly healed perception. This rising takes place due to the realization of the perfect innocence or holiness that is our true nature. This is followed by the ascension, by God taking the final step and lifting us into Heaven.
The resurrection of Jesus, the reawakening of his own mind (not the revivification of his body), which paved the way for his own return to knowledge (see CE T-3.VII.1:5), for his own final step (see CE C-5.1:1). The resurrection was not proof of Jesus’ divine status, but rather a demonstration of a general truth: that life cannot be destroyed, and indeed is the only reality (see CE T-3.III.8:1-2), that “there is no death” (mentioned eighteen times in the Course; see CE W-163_Heading). His resurrection set in motion the Atonement (see CE T-3.III.1:2). In it was contained the resurrection of the entire Sonship. Thus, by identifying with it we will experience our own resurrection. Although the reappearance of Jesus’ body can be seen as a symbol of the resurrection of his mind, the real resurrection was the disappearance of his body, not the reappearance, for that disappearance represented the removal of the limits that had been placed on the mind.
