The Nature of Sin: A Biblical, Lexical, and Confessional Analysis
Jack Kettler
Abstract
This paper offers a concise theological examination of the nature of sin according to Scripture and the Reformed confessional tradition. Sin is defined as any want of conformity to or active transgression of the moral law of God, encompassing both sins of commission and sins of omission. The study draws on key biblical texts, the Westminster Shorter Catechism, lexical analysis of the principal New Testament terms for sin, and Charles Hodge’s systematic exposition. It further situates the doctrine of sin in relation to original sin, total depravity, and the Fall, before concluding with the biblical and confessional resolution of human sin in the person and work of Christ.
Keywords: sin, law of God, commission, omission, original sin, total depravity, imputation, Reformed theology
1. Introduction
The doctrine of sin holds a foundational place in Christian theology, especially in the Reformed tradition. A precise understanding of sin is indispensable to a coherent account of the human condition, the necessity of redemption, and the work of Christ. This paper examines the nature of sin by integrating biblical testimony, confessional standards, lexical evidence, and classical systematic theology. The aim is to set forth a clear, historically grounded definition of sin and to show how it is resolved through the satisfaction and imputation accomplished by Jesus Christ.
2. Definition of Sin
“Sin may be defined as any lack of conformity, whether active or passive, to the moral law of God. This deficiency may appear in an act, a thought, or an inward disposition or state
Two complementary aspects are customarily distinguished. A sin of “commission” consists in the deliberate transgression of the revealed will of God—the explicit breaking of divine law. A sin of “omission” consists in the ethical failure to perform that which one is able and obliged to perform—the absence of conformity to what the law requires. In an active sense, the doing of what God forbids constitutes a sin of commission. In a negative sense, the failure to do what God commands constitutes a sin of omission.
Illustrative sins of commission include blasphemy, fornication, adultery, homosexuality, lying, drunkenness, murder, and slander. Illustrative sins of omission include remaining silent in the face of falsehood, withholding the truth, refusing to do good to those who require it when one has the power to assist, leaving necessary duties unfinished until opportunity has passed, and remaining silent in the face of evil.” (Erickson 578).
3. Biblical Foundations
Scripture confirms these definitions:
“Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law” (1 John 3:4).
This text from 1 John addresses the sin of commission.
“Therefore to him that knoweth to do good, and doeth it not, to him it is sin” (James 4:17).
This text from James addresses the sin of omission.
Additional passages establish the universality of sin and the necessity of repentance and union with Christ:
· “I tell you, Nay: but, except ye repent, ye shall all likewise perish” (Luke 13:3).
· “My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous” (1 John 2:1).
· “And the times of this ignorance God winked at; but now commandeth all men everywhere to repent” (Acts 17:30).
· “Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap” (Galatians 6:7).
· “All unrighteousness is sin: and there is a sin not unto death” (1 John 5:17).
· “Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death” (James 1:15).
4. Confessional Definition
The Westminster Shorter Catechism (Question 14) supplies a precise formulation:
Q. What is sin?
A. Sin is any want of conformity unto, or transgression of, the law of God.
The Catechism’s proof texts are 1 John 3:4, James 4:17, and Romans 3:23 (“For all have sinned, and come short of the glory of God”).
5. Lexical Analysis of the New Testament Vocabulary
“W. E. Vine’s “Expository Dictionary of New Testament Words” offers a detailed treatment of the principal terms for sin. The noun “hamartia” (literally “a missing of the mark”) is the most comprehensive term for moral obliquity. It is employed (a) of sin as a principle or source of action (e.g., Rom. 3:9; 5:12, 13, 20; 6:1–2; 7:7–13); (b) of sin as a governing power personified (e.g., Rom. 5:21; 6:12, 14; 7:11, 14, 17, 20, 23, 25; 8:2); (c) as a generic term sometimes inclusive of concrete wrongdoing (e.g., John 8:21, 34, 46; 9:41; 15:22, 24; 1 John 1:7–8; 3:4, 8–9); and (d) of a specific sinful deed (e.g., Matt. 12:31; Acts 7:60; Jas. 1:15; 2:9; 4:17; 5:15, 20; 1 John 5:16).
The related noun “hamartēma” denotes an act of disobedience to divine law (e.g., Mark 3:28; Rom. 3:25; 1 Cor. 6:18). The verb “hamartanō” (“to miss the mark”) is used of sinning against God, Christ, man, one’s own body, or earthly masters (e.g., Matt. 27:4; Luke 15:18, 21; John 5:14; 8:11; Rom. 2:12; 3:23; 5:12; 6:15; 1 Cor. 6:18; 7:28; 1 John 1:10; 2:1; 3:6, 8–9). Christ is uniformly predicated as without sin in every respect (2 Cor. 5:21; 1 John 3:5; John 14:30; John 8:46; Heb. 4:15; 1 Pet. 2:22) (Vine 1045–1047).”
6. The Protestant Doctrine of Sin (Charles Hodge)
“Charles Hodge summarizes the consensus of the Protestant churches at the time of the Reformation. Founding their doctrine upon moral and religious consciousness and upon the Word of God, they defined sin as the transgression of, or want of conformity to, the divine law. Melanchthon, Gerhard, Baier, and Vitringa all employ formulations that identify sin as “anomia”—a discrepancy from, or non-congruence with, the law of God that obliges the sinner to punishment under the order of divine justice.
Hodge extracts five propositions from these definitions: (1) sin is a specific evil, differing from all other forms of evil; (2) sin stands in necessary relation to law, so that where there is no law there can be no sin; (3) the law in view is the law of God, not merely the law of reason, conscience, or expediency; (4) sin consists essentially in the want of conformity of a rational creature to the nature or law of God; and (5) sin includes both guilt and moral pollution.
Consciousness itself discloses that sin is a specific evil known immediately by moral beings. It further discloses that sin is related to law: the word “ought” implies obligation under authority. The law that binds the conscience is that which has been revealed in the constitution of human nature, the Decalogue, the Mosaic institutions, and the whole of Scripture. Sin is neither a mere limitation of being, nor a subjective state without character before God, nor merely something unwise or inexpedient; it possesses a distinct character that includes both guilt and pollution.” (Hodge, Vol. 2, 180–182).
7. Related Doctrinal Categories
· “Original sin” denotes the sinful state and condition into which all human beings are born, comprising both imputed guilt (the guilt of Adam’s first sin reckoned to their account) and inherited corruption (a disposition toward sin).
· “Total depravity” affirms that the inherent corruption of humankind “extends to every part of our nature, to all the faculties and powers of both soul and body; and that there is no spiritual good, that is, good in relation to God, in the sinner at all, but only perversion.”
· The “Fall of man” refers to the disobedience of Adam and Eve in the Garden of Eden, whereby they transgressed the divine prohibition against eating of the tree of the knowledge of good and evil, resulting in God’s curse upon them and all their posterity.
8. The Resolution of Sin in Christ
The Heidelberg Catechism (Question and Answer 56) articulates the believer’s confession concerning the forgiveness of sins:
· Q. What believest thou concerning “the forgiveness of sins”?
· A. That God, for the sake of Christ’s satisfaction, will no more remember my sins, neither my corrupt nature, against which I have to struggle all my life long; but will graciously impute to me the righteousness of Christ, that I may never be condemned before the tribunal of God.
The apostle Paul writes:
“For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him” (2 Corinthians 5:21).
Matthew Poole comments:
“Christ knew no sin, as he was guilty of no sin… but God made him to be sin for us. He was numbered with the transgressors (Isaiah 53:12). Our sins were reckoned to him… He was made a sacrifice for our sins, a sin offering… That we might be made the righteousness of God in him; that so his righteousness might be imputed to us… As Christ was not made sin by any sin inherent in him, so neither are we made righteous by any righteousness inherent in us, but by the righteousness of Christ imputed to us” (Poole 616).
9. Conclusion
Sin is any want of conformity to, or transgression of, the law of God—whether by commission or omission, whether as principle, power, or particular act. Scripture, confessional standards, lexical data, and classical Reformed theology converge upon this definition. The universal guilt and corruption of humanity find their sole remedy in the substitutionary work of Christ, who was made sin for us that we might be made the righteousness of God in him.
