I’m not too sure what any of this has to do with what I’ve posted, but I will make a few comments on what you’ve said.
I highly doubt Fr. Pacwa does this, since it would violate the seal of confession. Making someone do something that outs him as having committed a sin as a condition for absolution is most definitely direct violation of the seal, and the priest would be excommunicated for that. It would be just like requiring a murderer to turn himself in to the police as a condition for absolution. A confessor may strongly encourage either of the above, but it cannot be required as a condition for absolution.
Again, you’re mostly just telling me what you kind of remember that Fr. Pacwa said, but if he said that, it’s a little presumptuous of the motives of his brother priests (without a source, I can’t actually be sure that he said this). There are good reasons to give easy penances. Penance isn’t like the punishment for a crime (hence there aren’t really sentencing guidelines). It’s more like medicine for a wounded soul. I have heard the old story many times of the priest who gave light penances to notorious sinners or to those who had been away from confession for a long time because he himself was fasting on behalf of the penitent. But I think that regardless, it’s a little presumptuous to say a priest is being “vastly negligent in his vocation and duties” to give light penances. Did Fr. Pacwa say that, or did you?
I don’t usually pray for this, it just happens. It is most likely some kind of grace from the Holy Spirit. It might also just be the sheer volume of fire–most people confess the same dozen or so things, and they all run together. It truly isn’t very exciting to remember any of it. Hearing confessions is actually kind of boring on that end of it. I say that, and it shocks people, but it’s true–hearing sins isn’t exciting. Hearing people seek the mercy of God, and then pronouncing his forgiveness over them, that’s the exciting part.
This isn’t really that big of a deal, or not nearly so big a deal as people would imagine that it is. Again, I hardly remember any of it. It’s not like I lie awake at night obsessing over the awful things people have done and feeling tempted toward doing them–I truly don’t remember any of it, or the vast majority of it anyway.
