Venial sins committed between your last confession and your earthly death will be payed for through temporal punishment (Purgatory), and then you go to heaven.
I’m snagging up on the idea that we “pay” for our sins in Purgatory or by acts performed on earth. The whole point of the death and resurrection of the Lord is that we are
not up to a quid pro quo system.
I may be nit-picking, but God is not running a demerit system on us. Consider the difference is between the parent who says, “you failed me, now you owe me” versus one who says that “what is broken must be fixed in order to work”. God, in justice, says both. Yes, we failed God and we owe God, more than we can repay. Jesus took care of that part, though. I don’t mean this to imply that God is petty. The cost to be paid is a real cost, though. Our need for salvation is not some sort of juridical technicality that God could have just waived, were God “nicer”. The debt Jesus paid is the real replacement of something really destroyed, replaced by a real sacrifice. We destroyed our own life, the life God gave us. Jesus brought life back to us.
What remains, though, is the fixing. The substance of our life in God is replaced, and that is a substance we had no power to supply ourselves, but the nature of the break remains, which is a break between our will and God’s. That restoration requires acts of our will to be fixed. You could look at it as Purgatory as being the place where our will holds still for fixing by God. In baptism, in confession, we come by our own free will for fixing by God.
Even our venial sins do real damage to our souls, damage that is not fixable except by the cooperation of our souls. We’re not going to make it through Purgatory except by admission that we need to be fixed in order to be made fit for heaven, and to cooperate in that repair. Nevertheless, those who insist that those little dings and nicks we hold to be of so little account when we commit venial sins are absolutely right: the damages do add up. Eternity is the light in which the damage is fully seen and the incompatiblity between God’s life and a broken ability to love is inescapable. The wise get to that damage now, and do not leave it all for Purgatory.
What is “broken” is our unity with God, the love in us. Because of the nature of love, this may only be repaired with our free cooperation. By mortal sin, we break away entirely and willfully from God. We break the connection between our will and God’s will. That is death for us. We have no life, apart from God’s will. If we die in a state where we have chosen to prevent repair, remaining in what is truly a state of death, then the fact that Jesus paid for our failure won’t force life onto us. By our own choice, we’re dead, we stay dead, and we live that unquenchable death forever.
The confession of mortal sins, especially, is how our will comes to God’s will for re-unification, by God’s action. By that re-unification, we return to God’s life. Again, though: the repair action is God’s work–we do not repair ourselves–but because the action is on our will, our will must cooperate and our being must experience the realities of the repair.
OK, now I’m sure I’ve thrown out something here that will read as a “snag” to somebody else…please chime in!
