According to The Bible, we cannot differentiate sin as minor or major. A minor sin is also a "Sin".
Missing the Mark
In Christianity it doesn't matter what sin you commit its the same as any other sin for example to lie is just as bad as murder in gods mind.
Sin
Roman Catholic AnswerThat would be mortal sin, as opposed to venial sin, which is less serious.
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.
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.
Joseph Bartlet has written: 'A serious call to such as are at ease in their sins' -- subject(s): Sin, Poetry
Mortal sin
1 Grave matter 2 full knowledge 3 complete consent All three of these conditions must be present for a sin to be mortal. If one or more of these conditions is not present, the sin is venial (less serious).
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.
It can be, there is no way for a third party to answer this question. You need to discuss this with your confessor, he can tell you where it would cross the line into serious sin for you. That being said, the whole discussion is bootless, as you should avoid any sin. Even venial (less serious sin) leads to mortal sin, so even venial sin should *always* be avoided if you love God and want to go to heaven.
