I have read that purgatory, while sometimes referred to as punishment, is intended to purge not only venial sins, but sinful attachments. As I understand it, baptism remits all temporal punishment, so if a person was baptized and happened to die immediately afterward, not having sinned, the person would go directly to heaven. But if that person still had sinful attachments, would they not still need purification? How does that work? This is the only aspect of the doctrine I really struggle with.
The spiritual life can be compared to a large block of rough marble and a stone artist.
When the artist begins, he uses his rough heavy chisels to take off large pieces. Then next he uses his light weight chisels to remove smaller pieces of marble. And finally, he uses his fine chisels to carve out the fingers, facial features, and other small details.
In the spiritual life the big pieces are mortal sins, medium pieces are venial sins, and the fine pieces are attachments and faults.
Jesus said “Be perfect as your Heavenly Father is perfect.” That is a tough word, perfect. Perfection is the goal in this life or the next.
So all of the bad stuff keeping us from attaching ourselves in perfect union with God has to go. That is what heaven is, perfect attachment and union with God.
Sometimes we don’t even recognize the attachments we have because we are blind to them. For example, someone could be blind to the fact that they talk too much and do not let others share in the conversation. They monopolize it. Yet don’t see this as a bit of uncharity to others because they see this as just being normal to them. They are blinded to their fault. In fact I believe some see this as a virtue in themselves. Everything should be in moderation. This is where prayer is important to ask God to open our eyes to the faults we don’t see.
Then too a person struggling with mortal sin is less likely to see venial sins, or if struggling with venial sins less likely to be looking for faults. But once sin is more or less under control, then God will show them their faults and imperfections and attachments. But they may choose or not choose to correct these. Then they may go forward or slide backward.
So in purgatory if we are still attached, that means there can be no perfect union with God until these are taken care of. So we may have more baggage or less baggage when entering purgatory.
So we should love God with all our heart, all our soul, and all our mind.
