LOL. No Refunds!
Actually, there are a couple of loopholes. Your mother could have gone to a prince of the Church, a bishop, or somebody higher, and beg forgiveness. It’s a process. Suplication in mind and spirit. Forgiveness could be granted if your father agreed to conversion after the fact and your mom would also have to pay a heavy penance for this very serious transgression. After your father’s conversion, a Catholic marriage could take place and all the children could then be baptised. But there would be a shitload of obligation to pay before this could happen.
As for you, you can begin the process of conversion as an adult practicing free will, get baptized into the Church, which would remove both the original sin of Adam and Eve and the mortal sin placed upon you, aka the “stain”, by your mother’s actions. Once you are a Catholic, your prayers for your mother’s soul will be heard by God.
I’m not sure how this works, because now we are getting into the mysteries and mysticism of the Church. But if all her children convert of their own free will and remain good practicing Catholics all their lives, pray for their mother’s soul, have annual requiem masses said for her, etc, there is a chance she could trade her condo in hell for better real estate in purgatory. Then, maybe in a couple of thousand years, she’ll finally be admitted to the great Catholic country club in the sky.
Basically, the damage she caused by her actions must be undone. If all the children become practicing, card carrying Catholics, the greater sin of producing children outside of the Church is undone.
This is something for a Jesuit to answer. Besides being the teachers of the dogma, they are also the lawyers of the Church. They can explain this stuff and take the case to Rome for reconsideration. Only wealthy people bother with it. Most Catholics don’t take this stuff seriously anymore.
The deal is to live a good life as a good person and everything will be OK. Most the practicing Catholics I know believe this. And I suspect the present Pope, a Jesuit egalitarian, does as well.
I find it all very interesting, but take it no more seriously than I do Greek mythology—as I’m sure you do as well.
