Question… If our mortal sins are forgiven and we are essentially just purging our venial sins, 1) why does it matter if you are St. Francis or a murderer who ends up going to purgatory? 2) If it does matter, would this conclude that purgatory is place of justice and ultimately ties to works? 3) If this is case, would this compromise God’s saving grace and imply that our sins aren’t fully forgiven? Why or why not? I understand this is likely a common fundamentalist question; I assure you, I am seeking the Catholic faith and would love to here an answer, or better yet, if my question is self-refuting within itself. Thank you!
Purgatory isn’t about “forgiveness” per se in the sense of guilt, i.e. eternal consequences attached to a sin. It is about the temporal consequences of a sin, which demand both a sense of justice in recompense and causes damage to the soul committing the sin.
Take for example, the letter to the Hebrews:
*Hebrews 12:7-10 It is for discipline that you have to endure.
God is treating you as sons; for what son is there whom his father does not discipline? If you are left without discipline, in which all have participated, then you are illegitimate children and not sons. Besides this, we have had earthly fathers to discipline us and we respected them. Shall we not much more be subject to the Father of spirits and live? For they disciplined us for a short time at their pleasure, but
he disciplines us for our good, that we may share his holiness.*Here you have an example of God, for the sake of holiness, effects discipline to people who are already His children. Now why would that be the case if all that was needed was to “forgive” a sin in the sense of not demanding the eternal punishment associated with it?
Purgatory is about holiness, purity, purification. That is vital to remember. The reason, even after forgiveness of sins, God still seeks to purify the soul, is because He desires the soul to be eternally united with Him. And since no blemish is compatible with God (e.g. Rev. 21:27), God sees that reconciliation includes the purification of the soul even if that soul is bound for heaven.
