Here is what the saints say about deathbed confessions:
St. Alphonsus Liguori
“The dying sinner will confess his sins, but, according to St. Augustine, ‘The repentance which is sought from a sick man is infirm.’ And St. Jerome says, that ‘Of a hundred thousand sinners who continue till death in the state of sin, scarcely one shall be saved.’ St. Vincent Ferrer writes, that ‘It is a greater miracle to save such sinners, than to raise the dead to life.’ They shall feel convinced of the evil they have done; they will wish, but shall not be able, to detest it.” Sermon XXXVIII.-On The Death of The Sinner
Now I have no intent whatsoever to indulge in sin and do a deathbed confession to try to loophole my way into heaven…
…but I have committed the sin of presumption many times in my life, and those who seek only a deathbed confession is basically just a very long, prolonged, presumption.
So when I see these quotes, it sounds like there is not much hope for people who commit the sin of presumption. I’m scared and want to know how the sin can be forgiven.
I’ve confessed it in the past and I regret ever presuming God’s mercy, but it sounds like it won’t matter because
‘It is a greater miracle to save such sinners, than to raise the dead to life.’ according to St. Vincent Ferrer.
The unhappy beings will go to confession at the hour of death; they will promise and weep, and ask mercy of God, but without knowing what they do.” Sermon XXXVIII.-On The Death of The Sinner
How would this sinner be damned? for “without knowing what they do”? Doesn’t a mortal sin have to have full knowledge and deliberate consent?
