What does the term "purgatory" refer to in Catholic belief?

The term "purgatory" in Catholic belief refers to a state of purification for souls who have died in a state of grace but still need to atone for minor sins or the temporal effects of sin before entering heaven. This concept is rooted in the understanding that while these souls are ultimately destined for heaven, they must undergo a process of purification to attain the holiness necessary to be in the presence of God.

Purgatory is seen not as a permanent state but rather a temporary one, where souls are cleansed and made ready for the beatific vision of God. This belief underscores the Catholic emphasis on God's mercy and the importance of purification before attaining eternal life.

In contrast, other choices describe different theological concepts. A reward for good deeds relates to the idea of heaven. Punishment for the wicked aligns more closely with the concept of hell. A place of eternal bliss refers specifically to heaven, which is distinct from the purification process that occurs in purgatory. Each of these alternatives highlights different aspects of Catholic eschatology, but they do not accurately represent the role and significance of purgatory within the belief system.
