The Catholic Church defines sin as an offense against reason, truth, and right conscience. Mortal sins are those that turn people away from God and destroy charity. They are considered more serious than venial sins, which weaken charity but do not deprive sinners of their friendship with God. Mortal sins require full knowledge and complete consent, meaning one must be fully aware of the sinful nature of their actions and consent to them deliberately. While doubt in the form of temptation is not considered a sin, voluntary doubt, or the deliberate refusal to accept revealed truths, is considered a mortal sin. However, it is important to note that feelings of fear and anxiety do not indicate the commission of a mortal sin, and seeking constant reassurance about one's actions can impede spiritual growth.

What You'll Learn

Doubt is a sin when it leads to unbelief
Doubt is a natural part of belief, and it is not inherently sinful. However, doubt can become sinful when it leads to unbelief, which is a rejection of God's existence and the Catholic Church's teachings. This is a complex topic within Catholic theology, and it is important to distinguish between involuntary and voluntary doubt.
Involuntary doubt refers to hesitation in believing, difficulty in overcoming obstacles connected with faith, or anxiety about the faith's obscurity. This type of doubt is usually not considered a sin, but if it is cultivated and not confronted, it can lead to spiritual blindness and may even become a mortal sin. On the other hand, voluntary doubt, which is the deliberate refusal to accept the truths revealed by God and proposed by the Catholic Church, is considered a mortal sin.
The Catechism of the Catholic Church defines atheism or the willful rejection of God's existence as "a sin against the virtue of religion" (CCC 2125, Rom. 1:18). Mother Teresa, like many saints, experienced severe temptations to doubt but persevered by standing firm in her faith and entrusting herself to God.
When facing doubts, Catholics have a choice: to march forward in faith and seek answers or to turn away from their beliefs. It is only when an individual chooses unbelief that doubt becomes sinful. This choice often comes down to one's willpower and commitment to their faith.
Additionally, it is important to understand the distinction between mortal and venial sins. A mortal sin is one that "destroys in us the charity without which eternal beatitude is impossible" (CCC 1874). It cuts us off from God forever unless redeemed by repentance and forgiveness. To be considered a mortal sin, three conditions must be met: grave matter, full knowledge, and deliberate consent (CCC 1861, 1862). Venial sins, on the other hand, do not meet all three conditions and do not deprive the sinner of sanctifying grace, friendship with God, or eternal happiness (CCC 1863). While they do weaken charity and impede spiritual progress, they do not have the same eternal consequences as mortal sins.

Mortal sins are not always against the Ten Commandments
While the Catholic Church has a clear definition of what constitutes a mortal sin, not all mortal sins are explicitly laid out in the Ten Commandments. The Commandments are a set of "first principles" that outline the moral law, but they are not exhaustive in their listing of serious sins.
The Catechism of the Catholic Church (CCC) defines a mortal sin as one that "destroys in us the charity without which eternal beatitude is impossible. Unrepented, it brings eternal death." In other words, a mortal sin cuts one off from God forever unless redeemed by repentance and God's forgiveness.
For a sin to be considered mortal, three conditions must be met: it must involve "grave matter," there must be "full consent of the will," and there must be "sufficient knowledge of the sinful character of the act." Grave matter refers to the seriousness of the sin, and the Catechism points out that one must consider who is wronged, as violence against parents, for example, is considered graver than violence against a stranger.
While some mortal sins, such as murder, are also explicit violations of the Ten Commandments, not all mortal sins are listed therein. For instance, missing Mass on Sundays and holy days is considered a mortal sin, as indicated in Church law (canon law). This law states that "on Sundays and other holy days of obligation, the faithful are obliged to participate in the Mass." Thus, willfully missing Mass without a "grave cause" is considered a serious or mortal sin.
Additionally, doubt and atheism are addressed in Catholic doctrine. Atheism, or the willful rejection of God's existence, is considered a sin against the virtue of religion. However, doubt in itself is not a sin, especially when it occurs in the form of a temptation. In fact, contemplating the mysteries of Christianity through doubt can be seen as a way to strengthen and clarify one's beliefs.
In conclusion, while the Ten Commandments provide a foundation for moral law in the Catholic Church, they do not encompass all possible mortal sins. The determination of a mortal sin hinges on the gravity of the matter, the consent of the will, and the knowledge of the sinner, with the ultimate consequence of severing one's relationship with God unless repentance is sought.

Mortal sins require full knowledge and consent
Mortal sins are those that "destroy in us the charity without which eternal beatitude is impossible", as the Catechism of the Catholic Church (CCC) puts it. Unrepented, they bring about "eternal death", cutting us off from God forever. However, not every evil action is mortally sinful.
For a sin to be considered mortal, three conditions must be met: grave matter, full knowledge, and deliberate consent. Grave matter refers to the seriousness of the sin. Full knowledge means that the sinner is aware of the gravity of their actions and understands that they are sinning. Deliberate consent implies that the sinner gives their full consent to the act, despite any misgivings, regrets, or mixed feelings they may have. It is important to note that the degree of knowledge and consent required is that needed for a fully human act.
In the context of questioning Catholic truth, doubt itself is not a sin. Both believers and unbelievers experience doubt, and it is only when the believer chooses unbelief that doubt becomes sinful. Involuntary doubt, such as hesitation in believing or difficulty in overcoming obstacles connected with faith, is typically considered a venial sin or no sin at all. However, if left unaddressed, involuntary doubt can cultivate and lead to serious spiritual blindness, becoming a mortal sin. On the other hand, voluntary doubt, or the deliberate refusal to accept revealed truths, is considered a mortal sin.
When determining whether a specific act of questioning Catholic truth constitutes a mortal sin, it is essential to seek guidance from a trusted confessor or spiritual director. They can help discern the presence of mortal sin by evaluating the action against sacred Scripture, canon law, and consistent Church teachings. Additionally, they can assist in determining the level of knowledge and consent involved in the act.
It is worth noting that seeking constant reassurance about one's moral life can be detrimental to spiritual growth. Individuals with scrupulosity should remind themselves that their feelings of fear and anxiety do not indicate the commission of a mortal sin. Instead, they should strive to trust their inner wisdom and make decisions with confidence, as this is considered natural and pleasing to God.

Mortal sins are against faith
Questioning Catholic truths can be considered a mortal sin in certain contexts. Mortal sins are defined as those that "contain injustice" and are directly opposed to the Ten Commandments, placing something else above God or turning individuals away from Him.
The Catechism of the Catholic Church identifies several sins against faith, including heresy, apostasy, and schism. Heresy refers to the obstinate denial of truths that must be believed with divine and Catholic faith after baptism. Apostasy is the total repudiation of the Catholic Faith, and schism is the refusal to acknowledge the primacy of the Roman Pontiff, leading to a schism within the Church.
Additionally, voluntary doubt, which involves deliberately disregarding or refusing to accept what God has revealed and what the Catholic Church proposes for belief, is considered a mortal sin. Involuntary doubt, on the other hand, refers to hesitation or difficulty in believing and is usually not a sin, but if left unaddressed, it can develop into a mortal sin.
It is important to note that mortal sins require "full knowledge" and "deliberate consent." As such, doubt in the form of temptation or involuntary doubt is not considered a sin. Doubt can even be seen as an opportunity to strengthen one's faith and deepen their understanding of Christianity.
When facing doubts or difficulties, individuals must choose whether to persevere in their faith and seek answers or to turn away from it. It is only when an individual chooses unbelief that doubt becomes sinful.

Doubt can be involuntary or voluntary
The Catechism of the Catholic Church defines atheism as a sin against the virtue of religion, as God has revealed Himself in nature. Nevertheless, doubt in the form of temptation is not considered a sin. In fact, it can be beneficial, as it encourages further contemplation of Christianity's mysteries, potentially strengthening religious conviction.
Mortal sins are those that "'contain injustice' and turn us away from God. They are serious, and they violate the supernatural love required to please God. They are not merely actions that are morally wrong but those that are also sinful and deadly, cutting us off from God forever unless redeemed by repentance and forgiveness. To be considered a mortal sin, an action must meet three criteria: grave matter, full knowledge, and deliberate consent.
Determining whether a sin is mortal can be complex, and it is not always a straightforward process. It is important to seek guidance from a trusted confessor or spiritual director rather than repeatedly seeking reassurance, which can fuel anxiety and impede spiritual growth.
