atoning sacrifice: the God-provided means by which sin is dealt with and the judgment it deserves is turned aside
This word names the atoning sacrifice itself, the provision that deals with sin and sets things right. In the wider Greek world before the New Testament, the family of words it belongs to meant winning back the favor of an angry god or ruler with a gift. The Greek Old Testament reshaped it: there God takes the initiative, and the word can even name God's own forgiveness. Both times it appears in the New Testament, in the same short letter, it describes not a ritual but a person: Jesus himself is the atoning sacrifice for our sins.
The phrase John uses, "the atoning sacrifice for our sins," deliberately echoes the sacrifice-for-sin language of the Old Testament law, where an offering was brought to cleanse guilt and restore a broken relationship. So the word points less to a feeling in God that has to be soothed and more to a concrete thing God supplies. Two close relatives fill out the picture: the verb ἱλάσκομαι, "to make atonement," and the noun ἱλαστήριον, the "mercy seat," the place in the tabernacle where atonement was made. Behind all of them stands the Hebrew verb כפר, "to make atonement."
The key to reading it rightly is the direction of the action. In this letter it is God who sends the Son as the atoning sacrifice, and he does it out of love; the sacrifice is not something people offer up to buy off a hostile God. Because sin does provoke real judgment, the act genuinely turns that judgment aside, but the whole movement begins in God's love rather than in human effort to appease him.
Disputed
What ἱλασμός denotes in 1 John: the turning aside of the divine judgment sin deserves (propitiation), the removal or cancellation of sin itself (expiation), or a fuller atoning-sacrifice sense that holds both dimensions together, with God as the source rather than the object of the action.
- majorityAn atoning sacrifice that holds both dimensions together: sin is removed and the judgment it provokes is averted, with God himself the source of the act. The old propitiation/expiation binary is a false choice.; Colin G. Kruse, The Letters of John (Pillar New Testament Commentary), 73-80; Stephen S. Smalley, 1, 2, 3 John (Word Biblical Commentary 51), 35-40; Jay Sklar, Sin, Impurity, Sacrifice, Atonement (Hebrew Bible Monographs 2, 2005)
- minorityExpiation: the cancellation and removal of sin, with the wrath-averting dimension excluded, since 1 John contains no wrath vocabulary and grounds the sending of the Son in divine love.; C.

- minorityPropitiation: the turning aside of God's wrath is central and cannot be removed from the word group, which never lost its propitiatory force in the first century.; Leon Morris, The Apostolic Preaching of the Cross (3rd ed. 1965), 144-213; Roger Nicole, "C. H. Dodd and the Doctrine of Propitiation," Westminster Theological Journal 17.2 (1955): 117-157; Robert W. Yarbrough, 1-3 John (Baker Exegetical Commentary)
- minoritySimple forgiveness or pardon, neither propitiation nor expiation, appealing to the Greek Old Testament of Psalm 129:4 and Daniel 9:9 where the word plainly means divine pardon.; Judith M. Lieu, I, II, & III John (New Testament Library, 2008)
