The Atonement for Sin in Scripture and Theology
Atonement denotes the reconciliation between God and humanity accomplished through sacrifice, removing the barrier of sin and restoring covenant relationship. The English term itself means "at-one-ment," signifying the state of being reconciled [2]. In the Old Testament, atonement was effected through the sacrificial system prescribed in the Mosaic law, where priests offered blood sacrifices to cover sin and purify both people and sacred spaces [1, 7]. The Day of Atonement ritual in Leviticus 16 stands as the central expression of this theology: the high priest made atonement for the sanctuary, the altar, and the entire assembly of Israel [1], addressing both the uncleanness and transgressions of the people [7].
The sacrificial system distinguished between sins committed unwittingly and those done willfully, with specific offerings prescribed for each category [4, 5]. Sin offerings were required not only for individual transgressions but also for ritual impurity, childbirth, and the consecration of priests [6]. The blood of these offerings was applied to the altar and, on the Day of Atonement, carried into the Holy of Holies and sprinkled on the mercy seat [6]. This mercy seat—the cover of the Ark of the Covenant—became emblematic of the atonement ceremony itself [9].
In the New Testament, Christ's death is presented as the fulfillment and replacement of the Old Testament sacrificial system. Paul describes Jesus as the hilastērion, the atonement cover, whom God put forward as the final provision for sin [9]. This sacrifice was voluntary [3], effected by Christ alone [3], and foreordained before the foundation of the world [3]. The atonement exhibits both God's justice and mercy: justice in that sin's penalty is fully addressed, and mercy in that God himself provides the means of reconciliation [3]. Forgiveness of sin, as a constituent part of justification, removes the sinner's liability to eternal wrath on account of Christ's work [8].
The New Testament uses "reconciliation" where the King James Version once rendered "atonement" (Romans 5:11) [2], emphasizing the relational restoration achieved through Christ's death. This reconciliation is offered freely to all in the gospel [8], grounded not in human merit but in the grace and love of God [3].

In the Old Testament it is of frequent occurrence. The meaning of the word is simply at-one-ment, i.e., the state of being at one or being reconciled, so that atonement is reconciliation. Thus it is used to denote the effect which flows from the death of Christ. But the word is also used to denote that by which this reconciliation is brought about, viz., the death of Christ itself; and when so used it”

- Easton's Bible Dictionary “Easton's Bible Dictionary: Forgiveness of sin — One of the constituent parts of justification. In pardoning sin, God absolves the sinner from the condemnation of the law, and that on account of the work of Christ, i.e., he removes the guilt of sin, or the sinner's actual liability to eternal wrath on account of it. All sins are forgiven freely (Acts 5:31; 13:38; 1 John 1:6-9). The sinner is by this act of grace for ever freed from the guilt and penalty of his sins. This is the peculiar prerogative of God (Ps. 130:4; Mark 2:5). It is offered to all in the gospel. (See [219]JUSTIFICATION.)”

The atonement cover was prominent in the Day of Atonement ritual (Lev 16) and came to stand for the atonement ceremony itself.
