In 1John 5., The Bible shows that there is a 'serious sin', and calls it 'a sin unto death':
16. If any man see his brother sin a sin [which is] not unto death, he shall ask, and he shall give him life for them that sin not unto death. There is a sin unto death: I do not say that he shall pray for it.
Jesus describes this type of sin in Mark 3, thus:
.
29. But he that shall blaspheme against the Holy Ghost hath never
forgiveness, but is in danger of eternal damnation:
30. Because they said, He hath an unclean spirit.
17. All unrighteousness is sin: and there is a sin not unto death.
Answer:
With all due respect... there is no such thing as a "trivial" or "lighthearted" sin.
Men like to marginalize "sin" and make it "not so bad" a thing, or a little less "serious" by making some of their sins, like lies, into "little white" ones. Or into a "fib." A "fib" is a "cuter" and less serious sin than a "lie" with men.
God, however, defines sin for us, so that there's no mistake: "...Sin is the transgression of the law." (I John 3:4)
Sin is lawlessness... anarchy... disobedience.
And: "...the wages of sin is DEATH..." (Rom.6:23).
And no matter what anyone says... "death is serious stuff."
Man has trampled God's Commandments under foot from the beginning... and is the reason why Jesus Christ had to come in the flesh to die for His creation; to pay the penalty [DEATH] for our sins.
And Jesus didn't willingly stumble to His death on the tree, lightheartedly. He would have been perfectly happy if His Father had suggested some other way:
"...O My Father, if it be possible, let this cup pass from Me: nevertheless not as I will, but as thou wilt." (Matt.26:39)
But, the fact that God had to die for His creation reveals the "seriousness" of ALL SIN -- of all transgressions against God's laws; better known as "disobedience."
Nor is God done with man's "disobedience" [sin] against Him. He is still quite serious about it:
"...for because of these things cometh the wrath of God upon the children of disobedience." (Eph.5:6)
The "seriousness" of our sins with God was magnified and made more serious than ever when Jesus Christ trudged to Golgotha and poured out His Divine blood into the earth for the sake of it. Sin was made even more deadly for those who fail to take Jesus' sacrifice for them "seriously."
Disobedient man's faithless disregard of Jesus' all-important act of God's offer of Salvation renders it "futile, worthless" and "empty of significance."
God has given men the opportunity to have their [very serious] sins blotted out through belief and faith in Jesus' selfless... tragic... act of Love -- and to have their names written in the "Book of Life."
And for all who stand outside of God's Love in continued "disobedience" and unabated sins... the consequences of any and all sin is still quite serious.
"...This is the SECOND DEATH. And whosoever was not found written in the Book of Life was cast into the Lake of Fire." (Rev.20:14-15)
Sin and death are the enemies of man... and they still live on and thrive in the world. Nor is God done with man's sins yet. He still has to get rid of both sin... as well as its "penalty."
The removal of the enemy, sin, has already been accomplish... for any who place their faith and trust in Jesus' shed blood.
But, contrary to popular belief in the world... Jesus Christ is ALIVE today. And He's coming back to earth in WRATH... to take care of the rest of God's and man's enemies [some of whom are disobedient men]:
"Then cometh the end... The last enemy that shall be destroyed is DEATH." (I Cor.15:24-26)
There are no "trivial" sins with God. He's still working to rid the world of it, altogether.
Sin is typically understood as actions or thoughts that violate moral or ethical standards, particularly those set by religious or legal authorities. It is often seen as harmful to oneself, others, or the natural order, and is considered to be contrary to divine or moral law. Each culture and belief system may have its own specific definitions of what constitutes sin.
There are two types of sin. Venial sin is a non-serious sin, when the sinner does not know it is wrong. Mortal sin is a serious sin, when the sinner is aware of what they are doing.
Mortal sin
Cloning of humans is definitely a serious (mortal) sin.
Sin importancia.
Yes, and no. The Catholic Church considers alcoholism as in drinking to excessive over a period of time a serious sin. Alcoholism, the condition where the body has become acclimated to a large consumption of alcohol would no longer be considered a serious sin, in and of itself, but the drinking that got you to that point would be considered a serious sin. To be considered a serious sin, free will must be involved, and a free decision. When you get to the point where there is little free will involved and little to no decision then you are looking at other sins perhaps, but no longer the original serious sin of just drinking to excess. Which is not to say that no sin is involved.
According to the Bible, we cannot differentiate sin as minor or major. A minor sin is also a "Sin".
The serious sin is ...ShiRk...(polytheism and/or henotheism)This means that the most serious sin is worshiping Idols as God partners or worshiping more than one God or believing that God has a partner, son, companion, or father.
Mortal sin. a example of a mortal sin could be murder, suicide, and more. Any sin that involves serious matter, knowledge, and consent of the will is mortal; then there is a venial sin. it is a less serious sin. You should still go to confession for either one of them though it is not strictly necessary for the remission of venial sin.
if you are truly repentant :)
Roman Catholic AnswerThat would be mortal sin, as opposed to venial sin, which is less serious.
Each religion has its own hierarchy of the seriousness of various sins, but betrayal is high on the list for all of them. "MOST" serious? Most religions rate blasphemy as a more serious sin than betrayal, although you could consider blasphemy as a betrayal of God, not just of man.
