The heavy subject of atonement is nothing to make light of. But reconciling to the Being of Light requires nothing less.
The word “atonement” means reparation for a wrong or injury. It derives from a word that denotes “unity” or “reconciliation,” especially between God and man. Its earliest form came from a now obsolete verb “to one” which meant to unite. Atonement was the combination of the word parts of at+ one + -ment.
