Live 4 The LORD

The Catholic Church distinguishes between mortal and venial sins, indicating that not all sins are equal in God's eyes [^2] [^9].

Here's a breakdown:

1.  **Mortal Sin**

2.  **Venial Sin**

3.  **Distinction**

#### Mortal Sin

Mortal sin is a grave offense against God that destroys charity in the heart of a person [^1] [^3] [^15]. It turns a person away from God, who is their ultimate end and beatitude, by preferring an inferior good to Him [^1] [^15]. For a sin to be mortal, three conditions must be met simultaneously: grave matter, full knowledge, and deliberate consent [^4] [^12]. This type of sin deprives the sinner of sanctifying grace and can lead to eternal death if unrepented [^4] [^7] [^12]. Mortal sins include acts such as blasphemy, perjury, homicide, and adultery because they are, by their nature, incompatible with charity [^5] [^13].

#### Venial Sin

Venial sin is a less serious offense against God [^2] [^6]. It weakens charity and manifests a disordered affection for created goods but does not break the covenant with God [^2] [^8] [^21]. A venial sin is committed when the matter involved is not serious, or when full knowledge or complete consent are absent, even if the matter is grave [^2]. Unlike mortal sin, venial sin does not deprive the sinner of sanctifying grace, friendship with God, or eternal happiness [^8] [^9] [^21].

#### Distinction

The essential difference between mortal and venial sin lies in whether the sin destroys charity in the heart [^1] [^3] [^15]. Mortal sin destroys charity and turns a person away from God [^1] [^3] [^15], while venial sin weakens charity without causing complete separation from God [^8] [^21]. Mortal sin necessitates a new initiative of God's mercy and conversion of heart, typically through the Sacrament of Reconciliation [^5]. Venial sin, while not breaking the covenant with God, still impedes the soul's progress in virtue and merits temporal punishment [^2] [^8] [^21]. The regular confession of venial sins is recommended to help form one's conscience and fight against evil tendencies [^26].
