According to Catherine’s teaching, a remarkable transformation occurs within the soul when it stands before God. The soul appears to be united and in total agreement with the holy will of God. There is no questioning to the length of time or the pain that they endure in Purgatory. There is no jealousy when another soul is released to heaven because one does not want to leave until all has been cleansed. When a soul is repentant at the hour of death, the guilt due to their sin is immediately forgiven, but the “rust” of sin is left, from which they will be cleansed by the pain of the fire. The pain that the soul experiences in Purgatory is similar to the pain of hell, but because the soul realizes the grievousness of sin and the great offense it is towards God, it would throw itself into Purgatory for as long as necessary.
