Scripture, on the other hand, affirms that it is Jesus Christ Himself who atones for sin and not our suffering in addition to what He has done on our behalf. His work on the cross has ensured that we obtain redemption and the forgiveness of sin:
"he entered once for all into the holy places, not by means of the blood of goats and calves but by means of his own blood, thus securing an eternal redemption." (Hebrews 9:12)
Scripture does not bring together our pain and suffering with the shed blood of Christ in the manner of making atonement:
"So Jesus also suffered outside the gate in order to sanctify the people through his own blood." (Hebrews 13:12)
"But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin." (1 John 1:7)
"And they sang a new song, saying, “Worthy are You to take the book and to break its seals; for You were slain, and purchased for God with Your blood men from every tribe and tongue and people and nation." (Revelation 5:9)
Christ's one offering put away sin and thus any other atoning work is rendered unnecessary:
"for then he would have had to suffer repeatedly since the foundation of the world. But as it is, he has appeared once for all at the end of the ages to put away sin by the sacrifice of himself. And just as it is appointed for man to die once, and after that comes judgment, so Christ, having been offered once to bear the sins of many, will appear a second time, not to deal with sin but to save those who are eagerly waiting for him." (Hebrews 9:26-28)
Roman Catholic apologists sometimes appeal to texts such as 2 Corinthians 1:5-7, Colossians 1:24, and Galatians 2:20 in order to substantiate the idea that our suffering can cancel out punishment for sins committed by ourselves and for other people when offered together with the sacrifice of Christ.
Regarding the text from 2 Corinthians, hardship for preaching the gospel resulted in it being shared and exemplified to the Christians dwelling at Corinth. Suffering can produce comfort and hope in God which can be shared with other people. In addition, the term "salvation" encompasses both the instance of "justification" and the ongoing process of "sanctification."
Regarding the text from Colossians, one commentator explains, "That which is behind of the sufferings of Christ — That which remains to be suffered by his members. These are termed the sufferings of Christ, 1. Because the suffering of any member is the suffering of the whole; and of the head especially, which supplies strength, spirits, sense, and motion to all 2. Because they are for his sake, for the testimony of his truth. And these also are necessary for the church; not to reconcile it to God, or satisfy for sin, (for that Christ did perfectly,) but for example to others, perfecting of the saints, and increasing their reward."
