But if someone’s work is burned up, that one will suffer loss; the person will be saved, but only as through fire (1 Corinthians 3:15).
Fire burns up everything that is perishable. That which isn't burned up by fire is the vessel in the kiln, that which is imperishable. The pure word of God. So the vessel comes out as gold. The verse is talking about the difference between the works of man, and the works of faith. It's not talking about a question of being saved. It already said that the person in Christ will be saved. It's the works that are in question.
At any rate, the burning occurs while in heaven at the Bema Seat of Christ, it doesn't happen in purgatory. Neither is the person sent from heaven to purgatory to do his laps before going to the showers.
And whoever speaks a word against the Son of Man will be forgiven; but whoever speaks against the holy Spirit will not be forgiven, either in this age or in the age to come (Matthew 13:32).
This is speaking of blasphemy of the Holy Spirit.. it's speaking of a fully spiritual adult in faith Christian who renounces Christ out of unrepentant pride or some other unredeemable reason. For this, they would at death be in with those at the white throne judgement, their destiny sealed for hell. Such a thing is very very rare among the Christians who truely love God with all their heart. Therefore, this scripture is not qualifiable for the average Christian.
Some will be saved only "through fire," and others will be forgiven "in the age to come."
It does not state that 'they' will be forgiven in the age to come. It says that they will not be forgiven, not even in the age to come.
These are good scriptural supports for purgatory.
The use of scriptures to support unbiblical theology is in violation of the text being used. Those verses do not indicate that they address purgatory.
What is called purgatory, is actually the area called Abraham's Bosom. Which doesn't exist anymore since it was taken up to heaven, along with all the Jewish saints when Jesus rose from the dead. After that, hell was enlarged, they moved in and occupied that emptied out area.
What is purgatory?
All who die in God's grace and friendship, but still imperfectly purified, are indeed assured of their eternal salvation; but after death they undergo purification, so as to achieve the holiness necessary to enter the joy of heaven (
CCC 1030).
Since they are assured of their eternal salvation while alive, then it's of no gain to them to undergo some sort of self effort of 'purification' before going to heaven.
What for?
The blood of Jesus to purify completely isn't somehow sufficient? One must do works of their own to achieve what Jesus blood supposedly did not?
That kind of theology is man's work based. It is a clear opposition to the scripture that says we are saved by faith not by works lest anyman should boast. Salvation is by grace, it is the unmeritable gift of God.
Purgatory is not according to Biblical text in the gospels, nor can such teachings be found in the epistles which were written to Christians.
