Recognizing Mortal Sin: A Guide To Understanding Your Actions

how to know if a sin is mortal

In Christian theology, a mortal sin is a gravely sinful act that can lead to damnation if a person does not repent before death. It is also referred to as a deadly, grave, or serious sin. According to the Catechism of the Catholic Church, a mortal sin is committed when three conditions are met: the sin must be of grave matter, it must be committed with full knowledge, and it must be done with deliberate consent. This means that mortal sins are committed intentionally, with an understanding of the sinful action and its gravity, and cannot be done accidentally. While various sins are considered grave matters, such as sacrilege, blasphemy, perjury, murder, sexual relations outside of marriage, and adultery, the Church does not provide an exhaustive list, as the evaluation of sin depends on context and circumstances.

Grave matter

The Catechism of the Catholic Church defines grave matter as "a sin whose object is grave matter". Grave matter is specified by the Ten Commandments, which include "Do not kill, Do not commit adultery, Do not steal, Do not bear false witness, Do not defraud, Honour your father and mother". The Catechism is explicit about the grave nature of particular sins, including sacrilege, blasphemy, perjury, deliberately avoiding Mass on Sundays and holy days of obligation, murder, hatred of a neighbour "when one deliberately desires him grave harm", prostitution, sexual relations outside marriage, and adulation that "makes one an accomplice in another's vices or grave sins".

The gravity of sins varies: for example, murder is considered graver than theft. The Catechism also states that "one must also take into account who is wronged: violence against parents is in itself graver than violence against a stranger".

In addition to the sins listed in the Catechism, St. Paul gives a list of grave sins in his letters to the Galatians and the Corinthians. These include adultery, fornication, idolatry, witchcraft, hatred, emulations, wrath, strife, seditions, heresies, envy, murders, drunkenness, and revellings.

The Church also identifies the following as grave matter:

  • Sins of anger, blasphemy, envy, hatred, malice, neglect of Sunday obligation, sins against faith (such as incredulity against God or heresy), sins against hope (such as obstinate despair in the hope for salvation), and sins against love (such as indifference towards charity, ingratitude, and hatred of God)
  • The four "sins that cry to heaven for vengeance": the voluntary murder, the sin of impurity against nature (sodomy and homosexual relations), taking advantage of the poor, and defrauding the working man of his wages
  • The seven capital sins or vices: pride, avarice, envy, wrath, lust, gluttony, and sloth (acedia)
  • Idolatry, divination, magic and sorcery, sacrilege, atheism, blasphemy, perjury and false oaths, deliberate failure of the Sunday obligation, abortion, euthanasia, suicide, scandal, drug abuse, gluttony, alcohol abuse, terrorism, extreme anger, hatred, extortion, adultery, divorce, fornication, pornography, prostitution, rape, homosexual acts, incest, masturbation, theft, cheating, defrauding a worker of his wages, unfair wagers, taking advantage of the poor, false witness and perjury, adulation, lying, lust, avarice, envy, voluntary doubt of faith, incredulity, heresy, apostasy, schism, despair in hope, presumption, indifference, ingratitude, lukewarmness, acedia (spiritual sloth), and hatred of God.

While this is a lengthy list, it is not exhaustive, and the right question to ask when evaluating the gravity of a sin is: "Is this the kind of behaviour that places something else above God or turns me away from God?"

Full knowledge

To be considered a mortal sin, full knowledge of the sin is required. This means that the sinner must have full knowledge of the sinful action and the gravity of the offence. The Catechism of the Catholic Church states that "mortal sin requires full knowledge and complete consent". It also presupposes knowledge of the sinful character of the act and its opposition to God's laws.

The Catechism further explains that "mortal sin is committed when a person knowingly and willingly, for whatever reason, chooses something gravely disordered". This means that the sinner must understand the seriousness of their actions and the potential consequences. They must be aware that their actions are in direct contradiction to God's laws and the divine law.

It is important to note that "unintentional ignorance can diminish or even remove the imputability of a grave offense". In other words, if a person does not fully understand the sinful nature of their actions due to a lack of knowledge or awareness, the seriousness of the sin may be reduced. However, the Catechism also states that "no one is deemed to be ignorant of the principles of the moral law, which are written in the conscience of every man". Therefore, while ignorance may be a mitigating factor, it does not completely absolve the sinner of responsibility.

In summary, full knowledge is a crucial component of a mortal sin. It requires the sinner to have a deep understanding of the sinful nature of their actions, the gravity of the offense, and the potential consequences. This knowledge must be accompanied by deliberate consent, indicating a personal choice to commit the sin despite the sinner's awareness.

The Catechism further explains that "the sinner's will is set upon something that, of its nature, involves a disorder, but is not opposed to the love of God and neighbour". For example, "thoughtless chatter or immoderate laughter" are considered venial sins rather than mortal sins because they do not directly contradict the love of God or neighbour.

In order for a sin to be considered mortal, it must be committed with full knowledge and consent, as well as involving grave matter. These three conditions must be met together for a sin to be classified as mortal.

Mortal sin vs venial sin

In Christian theology, a mortal sin is a gravely sinful act that can lead to damnation if a person does not repent before death. It is also referred to as a deadly, grave, or serious sin. A sin is considered "mortal" when it leads to a separation of that person from God's saving grace. On the other hand, a venial sin is a less serious sin that does not cut us off from Christ but weakens the grace in the soul and damages our relationship with God.

For a sin to be mortal, three conditions must be met:

  • It must be of grave matter: The sin must be a serious violation of God's law or the Ten Commandments, such as murder, adultery, theft, or bearing false witness.
  • It must be committed with full knowledge: The person committing the sin must be aware of the sinful nature of their actions and the gravity of the offense.
  • It must be committed with deliberate consent: The person must freely choose to commit the sin, indicating a rejection of God's law and love.

Venial sins, on the other hand, are those that do not meet all three of these criteria. They can be committed without full knowledge or deliberate consent, or they may involve less serious matters. While venial sins do not cut us off from God, they can weaken our relationship with God and make us more susceptible to committing mortal sins if left unaddressed.

It is important to note that the Church teaches that not every evil action rises to the level of a mortal sin, and the evaluation of a sin's seriousness depends on multiple factors. Additionally, the Church emphasizes the importance of confession and repentance for both types of sins, as God's mercy and forgiveness are always available to those who seek it.

Repentance and forgiveness

However, repentance and forgiveness can redeem mortal sins. Repentance is the primary requisite for forgiveness and absolution. The Catechism of the Catholic Church states that "mortal sin is redeemed by repentance and God's forgiveness" (CCC 1861). This process of repentance and absolution is facilitated through the Sacrament of Penance, also known as the Sacrament of Reconciliation.

The Sacrament of Penance involves confession, which is encouraged by the Church, especially for mortal sins. During confession, the penitent confesses their sins to a priest, expresses contrition or sorrow for their sins, and receives absolution. The priest, acting in the person of Christ, then grants forgiveness and may assign a penance, such as prayer or an act of charity, to aid in the penitent's reconciliation with God.

The effectiveness of absolution depends on the penitent's sincere sorrow for their sins and their firm resolution to sin no more. This is known as perfect contrition. While confession is typically required for the forgiveness of mortal sins, perfect contrition, coupled with the intention to confess as soon as possible, can restore a person's relationship with God and God's grace.

In addition to repentance and absolution, forgiveness for mortal sins may also be attained through God's infinite mercy. The Catechism of the Catholic Church states, "we can judge that an act is in itself a grave offence, we must entrust judgment of persons to the justice and mercy of God" (CCC 1861). This reflects the belief that, ultimately, God is the just and merciful judge of all persons, and that "there are no limits to the mercy of God" (CCC 1861).

Therefore, through sincere repentance, the Sacrament of Penance, and God's infinite mercy, forgiveness for mortal sins is attainable.
