What is define propitiation?

Propitiation is a theological concept that refers to the act of appeasing or satisfying the wrath of God, which is believed to be caused by human sin and disobedience. It involves offering a sacrifice or making an atonement for one's sins in order to achieve reconciliation with God. Propitiation is often associated with the sacrificial system of the Old Testament, where animals were offered as a symbol of confession and repentance. In Christian theology, Jesus Christ is often referred to as the ultimate propitiation, as his sacrifice on the cross is believed to have atoned for the sins of humanity and satisfied the wrath of God. The idea of propitiation is central to many Christian beliefs and practices, such as the sacrament of confession and the celebration of the Eucharist.
