That's true. However, the supposed benefit that's supposed to come from an indulgence relates to Purgatory, and both of these are doctrinal inventions that came from "Sacred Tradition."
And Scripture.
In
Matthew 5:26 and
Luke 12:59 Christ is condemning sin and speaks of liberation only after expiation. “Amen, I say to you, you will not be released until you have paid the last penny.” Now we know that no last penny needs to be paid in Heaven and from Hell there is no liberation at all; hence the reference must apply to a third place.
Matthew 12:32 says, “And whoever speaks a word against the Son of Man will be forgiven; but whoever speaks against the holy Spirit will not be forgiven, either in this age or in the age to come.” Here Jesus speaks of sin against the Holy Spirit. The implication is that some sins can be forgiven in the world to come. We know that in Hell there is no liberation and in Heaven nothing imperfect can enter it as we see in the next part. Sin is not forgiven when a soul reaches its final destination because in heaven there is no need for forgiveness of sin and in hell the choice to go there is already made.
Purgatory is an expression of God's Mercy. Consider this:
Imagine a Christian man, justified by the Lord, loses his temper and yells at his next door neighbors for letting their dog dig a hole in his yard. We can see that the man treated his neighbors rudely, albeit the neighbor’s behavior was also reprehensible. His actions would be considered a light sin (called
venial sins by the Catholic Church). It’s not of the same moral weight as theft or murder, but it’s still a sin.
After shouting at the neighbors, with all the anger and stress in his body the man walks into his house, has a heart attack, and dies having just committed a small sin in the final moments of his life. Remember, this man is Christian and justified by the Lord, yet has committed a sin. Does he go to heaven or does he go to hell? Are all sins created equal? No, all sins are not equal and even justified men of the Lord can make mistakes and sin.
If purgatory didn’t exist, the man would go to hell for his small sin. God’s mercy is so great and our God is a just God that it seems unfathomable that he would condemn a justified man to hell for a small, yet unrepented sin. The man’s soul is dirty. His actions have defiled his soul, but not the point where he has cut himself off from God. Only
mortal sins cut off a person from God’s grace. So, the man, having been justified by the Lord, is destined for heaven, yet his soul is defiled by his sin (Matthew 12:36, 15:18). His soul is in need of cleansing because nothing defiled can enter heaven. This is the purpose of purgatory. Out of mercy and love God sends the man through purgatory on his way to heaven so that his soul can be purified to be able to join God in heaven.
Remember, purgatory is not a second chance for conversion; the man is already justified. If there is no place of intermediate state of purification, the man would be damned to hell! Who would be saved? Those who teach against purgatory teach an unreasonable doctrine.
