Hello, i am a real Christian

[Paul the Human]

Purgatory is a Roman Catholic belief. Are you Roman Catholic? They get the idea from this:

The primary Scriptural passage Catholics point to for evidence of Purgatory is 1 Corinthians 3:15, which says, “If it is burned up, he will suffer loss; he himself will be saved, but only as one escaping through the flames.” The passage (1 Corinthians 3:12-15) is using an illustration of things going through fire as a description of believers’ works being judged. If our works are of good quality “gold, sliver, costly stones,” they will pass through the fire unharmed, and we will be rewarded for them. If our works are of poor quality “wood, hay, and straw,” they will be consumed by the fire, and there will be no reward. The passage does not say that believers pass through the fire, but rather that a believer’s works pass through the fire. 1 Corinthians 3:15 refers to the believer “escaping through the flames,” not “being cleansed by the flames.”

And the Catholic Church recently decided they were mistaken about that.

Other Christians believe:

Purgatory, like many other Catholic dogmas, is based on a misunderstanding of the nature of Christ’s sacrifice. Catholics view the Mass / Eucharist as a re-presentation of Christ’s sacrifice because they fail to understand that Jesus’ once-for-all sacrifice was absolutely and perfectly sufficient (Hebrews 7:27). Catholics view meritorious works as contributing to salvation due to a failure to recognize that Jesus’ sacrificial payment has no need of additional “contribution” (Ephesians 2:8-9). Similarly, Purgatory is understood by Catholics as a place of cleansing in preparation for heaven because they do not recognize that because of Jesus’ sacrifice, we are already cleansed, declared righteous, forgiven, redeemed, reconciled, and sanctified.
