Actually, Albion, he is correct.
Biblical proof for purgatory
2 Maccabees 12: 38-45 (RSVCE)
Then Judas assembled his army and went to the city of Adul′lam. As the seventh day was coming on, they purified themselves according to the custom, and they kept the sabbath there.
39 On the next day, as by that time it had become necessary, Judas and his men went to take up the bodies of the fallen and to bring them back to lie with their kinsmen in the sepulchres of their fathers. 40 Then under the tunic of every one of the dead they found sacred tokens of the idols of Jam′nia, which the law forbids the Jews to wear. And it became clear to all that this was why these men had fallen. 41 So they all blessed the ways of the Lord, the righteous Judge, who reveals the things that are hidden; 42 and they turned to prayer, beseeching that the sin which had been committed might be wholly blotted out. And the noble Judas exhorted the people to keep themselves free from sin, for they had seen with their own eyes what had happened because of the sin of those who had fallen. 43 He also took up a collection, man by man, to the amount of two thousand drachmas of silver, and sent it to Jerusalem to provide for a sin offering. In doing this he acted very well and honorably, taking account of the resurrection. 44 For if he were not expecting that those who had fallen would rise again, it would have been superfluous and foolish to pray for the dead. 45 But if he was looking to the splendid reward that is laid up for those who fall asleep in godliness, it was a holy and pious thought. Therefore he made atonement for the dead, that they might be delivered from their sin.
In the NT
Matthew 5:24-26 (parable for purgatory. We are pure in heaven, and there is no salvation in hell, so where is this prison that we go to pay our "coins" aka sins?)
Matthew 12:31-32 (if we are pure in heaven, where can sins be forgiven in this age to come?)
Matthew 18:23-35 (same parable, God will send us to jail to repay our debt, but we are pure in heaven, so where is this jail?)
1 Corinthians 3:10-15 (what is this fire to test our works? And even if our works burn up we will suffer but we will still be saved. We do not suffer in heaven, and our works cannot be judged until after our death.)
Hebrews 12:22-24 (who are the just men MADE perfect? Obviously they were not perfect when they died, but were MADE perfect. Where?)
Philippians 2:9-11 (where is this under the earth? Not hell, as that is the devils domain, and it is obviously a seperate place to both earth and heaven, so what is this place under the earth that all knees shall bow before Jesus?)
These clearly point to a place, outside of heaven and earth, where we will go to be to repay our sins, and we shall still bow to Jesus as Lord. This rules out hell, so where else could this be but Purgatory?
