Paul C You ask do I see how it works? NO! Can you explain it so I can understand what your talking about. ED
If you steal an apple from a homeless person even though you know that he has no other food, this can be a mortal sin since this deprives him of his sustenance for life. (If you are also homeless and have no food, then this may not be a mortal sin, but may instead be a venial sin; only God can judge your heart’s motives.) If you steal an apple from your neighbor’s fully-laden backyard tree, this most likely is a venial sin since this loss of one apple does not greatly affect him.
Adam and Eve ate the “fruit” and that caused all of us to “lose eternal life.” This is a “mortal sin” since God warned them that they would surely die (lose eternal life) if they ate it.
Mortal sin causes us to lose eternal life. So Adam and Eve committed the first “mortal” sin since it caused them and us to lose eternal life.
An example of the “degrees” of sin in the Bible:
Matthew 7:2-5 “For with what judgment you judge, you will be judged; and with the measure you use, it will be measured back to you. 3 And why do you look at the
speck in your brother’s eye, but do not consider the
plank in your own eye? 4 Or how can you say to your brother, ‘Let me remove the speck from your eye’; and look, a plank is in your own eye? 5 Hypocrite! First remove the plank from your own eye, and then you will see clearly to remove the speck from your brother’s eye.”
Examples of mortal sin (sins which cause us to lose eternal life) in Scripture:
Galatians 5:19-21 “Now the works of the flesh are evident, which are: adultery, fornication, uncleanness, lewdness, 20 idolatry, sorcery, hatred, contentions, jealousies, outbursts of wrath, selfish ambitions, dissensions,
heresies, 21 envy, murders, drunkenness, revelries, and the like; of which I tell you beforehand, just as I also told you in time past, that **those who practice such things will not inherit the kingdom of God.” **
1 Timothy 5:8 “But if anyone does not provide for his own, and especially for those of his household,
he has denied the faith and is worse than an unbeliever.”

There are many more Scriptural examples of “mortal” sins. Any sin which causes us to lose eternal life is a mortal sin.
Paul warned the Galatians that if they “turned away” from his preaching and instead believed that circumcision of the OT Covenant would save them, then they would lose eternal life. This is an example of “heresy” and so those who believed this
heresy fell from grace and severed themselves from Christ. In order to become justified again, they had to repent and confess. They
lost eternal life when they became
heretics.
Galatians 5:1-7 “For freedom Christ has set us free; stand fast therefore, and do not submit again to a yoke of slavery. 2 Now I, Paul, say to you that** if you receive circumcision, Christ will be of no advantage to you.** 3 I testify again to every man who receives circumcision that he is bound to keep the whole law. 4
You are severed from Christ, you who would be justified by the law; you have fallen away from grace. 5 For through the Spirit, by faith, we wait for the hope of righteousness. 6 For in Christ Jesus neither circumcision nor uncircumcision is of any avail, but faith working through love. 7
You were running well; who hindered you from obeying the truth?”
