Reference: PROPITIANTION
American
The offering which appeases the wrath of one against whom an offence has been committed. Christ is "the propitiation for our sins," Ro 3:25, inasmuch as his sacrifice alone removes the obstacles which prevented the mercy of God from saving sinners, and appeases the just wrath of the law, 1Jo 2:2; 4:10. The same Greek word is used in the Septuagint to denote an "atonement," Nu 5:8; a "sin-offering," Eze 44:27; and the covering of the Ark of the Covenant, Le 16:14; Heb 9:5. See MERCY SEAT.
