No ... Purgatory misrepresents the reward system. Protestantism that I know represents rewards that given or taken away as works burnt.
Here's the long version ..
Many use the doctrine of purgatory to explain away what is easily rightly divided in the Word in recognition of the difference between the millenium and eternity. Like the prophets of old who couldn't see the church age in the valley when viewing eternity, so too with these 2 trains of thoughts, they can't see the valley of the millenium when viewing eternity. The prophets of old had an excuse.
1 Peter 1:12
It was revealed to them that they were serving not themselves but you, in regard to the things that have now been announced to you through those who brought you good news by the Holy Spirit sent from heaven—things into which angels long to look!
AND this is definately Not confined to any specific denominations even tho they don't term it as purgatory.
Neither of these schools recognize the reward of the kingdom; even moreso, they do not see the suffering of the loss of the kingdom reward. Both consider all the negative points in verses refering to the rewards as referring to perdition.
School A , believing in eternal salvation regards all the negative points of reward scripture as applying to the perdition of false believers; while
school B, believing that a saved person will perish if he falls, regards these points as applying to the perdition of believers who have fallen.
But the complete revelation of the Bible shows that these negative points refer to the suffering of the loss of the kingdom reward. God's salvation is eternal; once we obtain it, we will never lose it John 10:28-29. But we may suffer the loss of the kingdom reward, even though we still will be saved 1 Corinthians 3:8, 1 Corinthians 3:14-15.
Hebrews 6
school A refers to those who have fallen away yet have repented in baptism, tasted of the heavenly (note John the baptist had the ministry of baptism of repentance) (not to be repeated) while Hebrews 10
school B refers to those who never believed but treated His sacrifice as a common thing and insulted the Holy Spirit. STOP your both right! But what your wrong on is the lack of discernment toward rewards~!
Hebrews 12:28
Therefore receiving an unshakable kingdom, let us have grace, through which we may serve God well-pleasingly with piety and fear;
The Hebrew believers had received the kingdom, but they risked losing the reward in the manifestation of the kingdom if they shrank back from the grace of God, from God's new covenant way.
The kingdom in its reality is an exercise and a discipline to us Matthew 5:3, 10, 20; Matthew 7:21 in the church today whereas the kingdom in its manifestation will be a reward and an enjoyment to us Matthew 16:27; Matthew 25:21, 23 in the millennial kingdom in the coming age.
If we take the Spirit's exercise and God's discipline in the reality of the kingdom today, we will receive the Lord's reward and enter into the enjoyment of the coming Sabbath rest Hebrews 4:9 in the manifestation of the kingdom in the coming age.
Otherwise, we will miss the coming kingdom, we will not be rewarded with the manifestation of the kingdom at the Lord's coming back, we will have no right to enter into the glory of the kingdom to participate in Christ's reign in the millennial kingdom, and we will lose our birthright and therefore will be unable to inherit the earth in the coming age, to be the royal priests serving God and Christ in His manifested glory, and to be Christ's co-kings ruling all the nations with His divine authority Revelation 20:4, 6.
To miss the coming kingdom and to forfeit our birthright does not mean that we will perish. It means that we will lose the reward but not our salvation. We will suffer loss but still will be saved, yet so as through fire 1 Corinthians 3:14-15.
This is the basic concept on which all five warnings in Hebrews are given and with which they are all pervaded. All the negative points of these warnings are related to the suffering of the loss of the reward in the coming kingdom, whereas all the positive points are related to the reward and enjoyment of the kingdom. All seven epistles in Revelation 2 and 3 conclude with this same concept — the reward of the kingdom or the loss of it.
