What is sin? What is grace?

Q. What is personal sin?

In contrast to original sin, personal sin represents the sins that we individually commit and for which we are personally responsible.

We all have a general sense of what personal sin is—that it involves doing something wrong, something evil, something we should not do. However, theologians have studied the concept, and the Church has a refined understanding of what sin is.

Put in general terms, sin is “an abuse of the freedom that God gives to created persons so that they are capable of loving him and loving one another” (CCC 387). Stated another way, it is “an offense against reason, truth, and right conscience; it is failure in genuine love for God and neighbor caused by a perverse attachment to certain goods” (CCC 1849).

In other words, we can become so attached to various good things—like pleasure, possessions, or popularity —that we make choices that put these things over the love we should have for God and for our fellow human beings. When we do this, we sin.

All sin involves an unloving choice based on disordered desire, or concupiscence. Originally, this word referred to any intense form of human desire, but in Christian thought it has taken on a special meaning. “St. John distinguishes three kinds of covetousness or concupiscence: lust of the flesh, lust of the eyes, and pride of life” (1 John 2:16)” (CCC 2514).

This triple concupiscence subjugates man “to the pleasures of the senses, covetousness for earthly goods, and self-assertion, contrary to the dictates of reason” (CCC 377).

When we are led by disordered desire into making unloving choices, the resulting sin will be one of two types: mortal or venial.

The first type is known as mortal sin because it produces spiritual death. It destroys the virtue of charity in our hearts, charity being the supernatural love of God that unites us to Him spiritually. By being separated from God in this way, mortal sin puts us in a state of spiritual death.

“For a sin to be mortal, three conditions must together be met: Mortal sin is sin whose object is grave matter and which is also committed with full knowledge and deliberate consent” (CCC 1857).

The first of these conditions means that the sin must involve a matter that is grave in nature. “Grave matter is specified by the Ten Commandments, corresponding to the answer of Jesus to the rich young man: ‘Do not kill, Do not commit adultery, Do not steal, Do not bear false witness, Do not defraud, Honor your father and your mother’ (Mark 10:19)” (CCC 1858).

Some sins automatically involve grave matter. This is the case anytime an innocent human being is killed and any time an act of adultery is committed.

If grave matter is present, there are still two other conditions that need to be fulfilled for a sin to be mortal. “Mortal sin requires full knowledge and complete consent. It presupposes knowledge of the sinful character of the act, of its opposition to God’s law. It also implies a consent sufficiently deliberate to be a personal choice” (CCC 1859).

Various factors can diminish or remove the knowledge and consent needed for a sin to be mortal. “Unintentional ignorance can diminish or even remove the imputability of a grave offense. . . . The promptings of feelings and passions can also diminish the voluntary and free character of the offense, as can external pressures or pathological disorders” (CCC 1860).

When a person commits a sin and one or more of the conditions needed for it to be mortal are not present, the result is a venial sin (CCC 1862). Venial sins offend and wound the virtue of charity, but they do not destroy it, which is why they are not mortal (CCC 1855). They thus do not lead to spiritual death.

When our sins are mortal, however, our souls are in jeopardy, and we are in urgent need of God’s grace.

Q. What is grace?

Looked at one way, grace is the antidote to sin. It is what God provides us to overcome both original and personal sin.

“Grace is favor, the free and undeserved help that God gives us to respond to his call to become children of God, adoptive sons, partakers of the divine nature and of eternal life” (CCC 1996).

We need grace because of the condition of spiritual poverty that we are born into as a result of original sin. In this state of separation from God, wounded human nature will not allow us to seek God and come to him. He must take the initiative by seeking us and giving us the help we need to freely choose him. Thus Jesus tells us, “No one can come to me unless the Father who sent me draws him” (John 6:44).

Fortunately, God wants all men to have this opportunity. He “desires all men to be saved and to come to the knowledge of the truth” (1 Tim. 2:4), and so he offers all men the grace necessary to be saved (CCC 1260).

God did not have to do this. He does it freely, out of his love for all men, and we must freely choose whether or not to respond to his grace and accept his love. “God’s free initiative demands man’s free response, for God has created man in his image by conferring on him, along with freedom, the power to know him and love him. The soul only enters freely into the communion of love. God immediately touches and directly moves the heart of man. He has placed in man a longing for truth and goodness that only he can satisfy” (CCC 2002).

The particular helps that God gives us at certain moments in life—helps to come to him, to do good, or to resist sin—are known as actual graces (CCC 2000). They can take many forms. When someone preaches the gospel and we are moved to respond, that is a grace. When we see someone in need and are moved to help, that is a grace. And when our conscience warns us that something we are about to do is wrong, that also is a grace.

Actual graces appear at particular moments in our lives, but there is another kind of grace, which remains with us over the course of time. This is known as sanctifying grace.

“Sanctifying grace is the gratuitous gift of his life that God makes to us; it is infused by the Holy Spirit into the soul to heal it of sin and to sanctify it. Sanctifying grace makes us ‘pleasing to God’” (CCC 2023-2024).

When a person has sanctifying grace, he is said to be in a state of grace. In this state, he is united with God spiritually and said to be in God’s friendship. If he dies in the state of grace, he will go to heaven (though he may need to be purified first in purgatory).

When we come to God and are saved and justified, God gives us the theological virtues of faith, hope, and charity (CCC 1991). Of these, charity is the most important (1 Cor. 13:13). It is the virtue “by which we love God above all things for his own sake, and our neighbor as ourselves for the love of God” (CCC 1822).

Charity always accompanies sanctifying grace, and when one is eliminated, so is the other.

This is why mortal sin “results in the loss of charity and the privation of sanctifying grace, that is, of the state of grace. If it is not redeemed by repentance and God’s forgiveness, it causes exclusion from Christ’s kingdom and the eternal death of hell” (CCC 1861).

In addition to sanctifying grace, God also gives us additional gifts of grace to help us live the Christian life and be of service to others.

Our salvation is thus entirely a product of God’s grace, from the graces that lead us to turn to him, to the state of grace in which we are saved, to the graces that he gives us to live the Christian life, to help others, and to bring them to him as well.
