Biblical references for Purgatory

Paul tells us that, when we are judged, each man’s work will be tried. And what happens if a righteous man’s work fails the test? "He will suffer loss, though he himself will be saved, but only as through fire" (1 Cor 3:15). Now this loss, this penalty, can’t refer to consignment to hell, since no one is saved there; and heaven can’t be meant, since there is no suffering ("fire") there. The Catholic doctrine of purgatory alone explains this passage.

"nothing unclean shall enter [heaven]" (Rev. 21:27). Anyone who has not been completely freed of sin and its effects is, to some extent, "unclean." Through repentance he may have gained the grace needed to be worthy of heaven, which is to say, he has been forgiven and his soul is spiritually alive. It is entirely correct to say that Christ accomplished all of our salvation for us on the cross. But that does not settle the question of how this redemption is applied to us. Scripture reveals that it is applied to us over the course of time through, among other things, the process of sanctification through which the Christian is made holy. Sanctification involves suffering (Rom. 5:3–5), and purgatory is the final stage of sanctification that some of us need to undergo before we enter heaven. Purgatory is the final phase of Christ’s applying to us the purifying redemption that he accomplished for us by his death on the cross.

The Fundamentalist resistance to the biblical doctrine of purgatory presumes there is a contradiction between Christ’s redeeming us on the cross and the process by which we are sanctified. There isn’t. And a Fundamentalist cannot say that suffering in the final stage of sanctification conflicts with the sufficiency of Christ’s atonement without saying that suffering in the early stages of sanctification also presents a similar conflict. The Fundamentalist has it backward: Our suffering in sanctification does not take away from the cross. Rather, the cross produces our sanctification, which results in our suffering, because "for the moment all discipline seems painful rather than pleasant; later it yields the peaceful fruit of righteousness" (Heb. 12:11).

Purgatory makes sense because there is a requirement that a soul not just be declared to be clean, but actually be clean, before a man may enter into eternal life. After all, if a guilty soul is merely "covered," if its sinful state still exists but is officially ignored, then it is still a guilty soul. It is still unclean.

Catholic theology takes seriously the notion that "nothing unclean shall enter heaven." From this it is inferred that a less than cleansed soul, even if "covered," remains a dirty soul and isn’t fit for heaven. It needs to be cleansed or "purged" of its remaining imperfections. The cleansing occurs in purgatory. Indeed, the necessity of the purging is taught in other passages of Scripture, such as 2 Thessalonians 2:13, which declares that God chose us "to be saved through sanctification by the Spirit." Sanctification is thus not an option, something that may or may not happen before one gets into heaven. It is an absolute requirement, as Hebrews 12:14 states that we must strive "for the holiness without which no one will see the Lord."
