Sin

Definition of sin

Catechism [CCC 1871]:

Sin is an utterance, a deed, or a desire contrary to the eternal law (St. Augustine, Faust 22: PL 42, 418). It is an offense against God. It rises up against God in a disobedience contrary to the obedience of Christ.

sin is an offense against God
sin is disobedience to God
sin is "knowing it is wrong and doing it anyway"

Etymology

from OE synn for "moral wrongdoing, injury, mischief, enmity, feud, guilt, crime, offense against God, misdeed"

from PIE *snt-ya-, forming *es-ont- for "becoming"
- in Germanic language groups, took on meaning of "it is true". as in "the sin is real"

Sin as separation from God

Jesus taught (Mt. 12:30)

Whoever is not with me is against me, and whoever does not gather with me scatters.

"scatter" means separated from God
- the word "devil" comes from , which means "to scatter"
therefore sin is separation from God
and eternal separation from God is hell.

Slavery to sin

From CCC 1739:

By refusing God's plan of love, [man who freely sinned] deceived himself and became a slave to sin.

Forgiveness of sin

CCC 431:

"Because sin is always an offences against God, only he can forgive it"

The Sacrament of Reconciliation repairs our offences against God.

Avoidance of sin

Jesus tells us very specifically how to avoid sin.

The "occasion of sin"

In the Beatitudes, Jesus advises that we avoid sin by distancing ourselves from it. In what seems harsh advice, in Mt 5:29-30, he says,

"If your right eye causes you to sin, tear it out and throw it away. It is better for you to lose one of your members than to have your whole body thrown into Gehenna. “And if your right hand causes you to sin, cut it off and throw it away. It is better for you to lose one of your members than to have your whole body go into Gehenna.”

Prayer

In the Garden of Gethsemane, Jesus tells the sleeping Peter, John and James, Mk 14:38:

"Watch and pray that you may not undergo the test. The spirit is willing but the flesh is weak."

If your right eye causes you to sin, tear it out and throw it away. It is better for you to lose one of your members than to have your whole body thrown into Gehenna.

“And if your right hand causes you to sin, cut it off and throw it away. It is better for you to lose one of your members than to have your whole body go into Gehenna.” (Mt 5:29-30)

o = Avoiding the “occasion of sin” (its place, opportunity, temptation)

Origin of sin in man

For from the heart come evil thoughts, murder, adultery, unchastity, theft, false witness, blasphemy. (Mt 15:19)

Three-fold sins

lust of the flesh
- disordered desire, especially sexual, but also for things
- indulgence, in self, in a substance, in wants
lust of the eyes
- wanting what is not yours
pride of life
- putting oneself or worldly things above God
- idolatry

The three-fold sins are recurring markers for the sins of men and nations across the Old Testament and in the History of Salvation.

Classifications and types of sin

St. Paul on sins or "works of the flesh":

Now the works of the flesh are obvious: immorality, impurity, licentiousness, idolatry, sorcery, hatreds, rivalry, jealousy, outbursts of fury, acts of selfishness, dissensions, factions (Gal 5:19-20)

From CCC 1853:

Sins can be distinguished according to their objects, as can every human act; or according to the virtues they oppose, by excess or defect; or according to the commandments they violate. They can also be classed according to whether they concern God, neighbor, or oneself; they can be divided into spiritual and carnal sins, or again as sins in thought, word, deed, or omission. The root of sin is in the heart of man, in his free will, according to the teaching of the Lord: "For out of the heart come evil thoughts, murder, adultery, fornication, theft, false witness, slander. These are what defile a man." But in the heart also resides charity, the source of the good and pure works, which sin wounds.

which we can organize as

Venial sin

"venial" is from Latin venia for "forgiveness" or venialis for "pardonable"

"venal" means "susceptible" or "motivated by bribery"
"venial sin" is sin that does not destroy the divine life (CCC 1855)
i.e., not "grave matter"
- or if in grave matter, not in full knowledge or consent of the sin
venial sin causes us to deviate from God's will and weakens our own spiritual health
the crucial difference between venial and mortal sin is that mortal sin may not be pardoned through prayer
- see 1 Jn 5:15-18

And if we know that he hears us in regard to whatever we ask, we know that what we have asked him for is ours.
If anyone sees his brother sinning, if the sin is not deadly, he should pray to God and he will give him life. This is only for those whose sin is not deadly. There is such a thing as deadly sin, about which I do not say that you should pray.
All wrongdoing is sin, but there is sin that is not deadly.
We know that no one begotten by God sins; but the one begotten by God he protects, and the evil one cannot touch him.

proliferation of sin

the danger of venial sin, while not mortal, it tends to lead to worser sins

per CCC 1865:

Sin creates a proclivity to sin; it engenders vice by repetition of the same acts. This results in perverse inclinations which cloud conscience and corrupt the concrete judgment of good and evil. Thus sin tends to reproduce itself and reinforce itself, but it cannot destroy the moral sense at its root.

we can think of venial sin as a "gateway" to mortal sin
- ex.:
  - ongoing resentment and anger can lead to hate, which violates Jesus' direct command to "love your neighbor as yourself" (Mk 12:31)
  - casual and habitual cursing can lead to denigration of God and thus violation of the Second Commandment to "keep holy God's name"

vice

vice is habitual sin or habits that lead to sin
per CCC 1866: "Vices can be classified according to the virtues they oppose"
"the vices" are "pride, avarice, envy, wrath, lust, gluttony, and sloth or acedia" (CCC 1866)
- pride = elevated sense of "self"; making oneself more important than God
- avarice = disordered desire for more of something than is necessary of sufficient; i.e., wanting more
- envy = disordered desire for what another has, is or owns, especially with jealousy
- wrath = anger
- lust = desire, especially but not only physical desire
- gluttony = over-indulgence, especially in eating and drinking, but also for experiences and behaviors
- sloth = desire to not do something that should be done; may also regard belief, attitude, or outlook
  - acedia = "a form of depression due to lax ascetical practice, decreasing vigilance, carelessness of heart" (CCC 2733)
    - i,e. not just weak faith, but deliberately or carelessly weak or weakened ("lax") faith and prayer
    - sometimes called "going through motions" as in doing something lackadaisically or without focus

temptation

Mortal sin

capital sin

"capital sin" or "capital vice" (CCC 1866)
also called the "Seven Deadly Sins"
- pride, covetousness, lust, anger, gluttony, envy, and sloth
"capital" because these are the "head" of other sins (i.e., lead to them)
"deadly" because they lead to death and damnation

mortal sin

"mortal" because it separates us from God
1 Jn 5:16:

If anyone sees his brother sinning, if the sin is not deadly, he should pray to God and he will give him life. This is only for those whose sin is not deadly. There is such a thing as deadly sin, about which I do not say that you should pray.

mortal sin may only be removed through the Sacrament of Reconciliation

the "Unforgiveable sin"

From Mt 12:30

Therefore, I say to you, every sin and blasphemy will be forgiven people, but blasphemy against the Spirit will not be forgiven.

per USCCB Bible footnote Mt 12:31: "Blasphemy against the Spirit: the sin of attributing to Satan (Mt 12:24) what is the work of the Spirit of God (Mt 12:28).

Mt 12:31:

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.
