Gospel Teachings on Cutting Off Body Parts for Sin

Jesus' teaching on cutting off body parts that cause one to sin is found in Matthew 5:29-30, where he says, "If your right eye causes you to stumble, gouge it out and throw it away... And if your right hand causes you to sin, cut it off and throw it away" ^[2]. This radical instruction has been interpreted in various ways throughout Christian history.

The biblical context for this teaching is Jesus' Sermon on the Mount, where he emphasizes the importance of inner righteousness and warns against the consequences of sin. The imagery of cutting off body parts is likely hyperbolic, emphasizing the need for drastic action to avoid sin. This interpretation is supported by the fact that Jesus also teaches that it is not what enters the body that defiles a person, but what comes out of the heart (Matthew 15:1-20).

The early Church Fathers understood this teaching as a call to spiritual discipline and mortification. For example, Origen and Clement of Alexandria interpreted it as a metaphor for renouncing sinful desires and behaviors ^[8]. John Chrysostom, an Eastern Orthodox Father, saw it as a call to crucify the "body of sin" (Romans 6:6), emphasizing the need to put to death sinful tendencies ^[10].

In the Reformed tradition, this teaching has been understood as a call to rigorous self-discipline and repentance. Charles Hodge, a 19th-century Reformed theologian, saw it as a manifestation of the law's demand for holiness, emphasizing that true repentance involves a willingness to sacrifice even the most precious things to avoid sin ^[6]. Matthew Henry, a Nonconformist/Puritan commentator, interpreted it as a call to "arm yourselves with the same mind and resolution as Christ" and to mortify sin in one's life ^[11].

The Catholic tradition, as represented by Thomas Aquinas, has also grappled with the literal and figurative implications of this teaching. Aquinas argued that while it is not lawful to literally maim oneself, it is lawful to sacrifice a part for the sake of the whole, just as a decayed member may be amputated to save the body ^[9].

In Jewish tradition, the concept of "cutting off" has a different connotation, often referring to the punishment or consequence of sin. For example, in the Babylonian Talmud, "cutting off" is discussed in the context of ritual purity and the consequences of sin ^[5]. Ramban (Nachmanides), a medieval Jewish commentator, interpreted the phrase "cut off" in Leviticus 18:29 as referring to the spiritual excision of the soul from the community ^[7].

The biblical teaching on cutting off body parts for sin is closely tied to the broader themes of sin, repentance, and redemption. In 1 Peter 2:24, the apostle Peter writes that Christ "bore our sins in his body on the tree, so that we might die to sin and live to righteousness" ^[3]. This understanding of Christ's sacrifice as a substitutionary atonement for sin is a central aspect of Christian theology.

The practice of cutting or mutilating one's body was also a feature of some ancient pagan and idolatrous practices, which the Israelites were forbidden to imitate (Leviticus 19:28; 21:5; Deuteronomy 14:1) ^{[1, 4]}. The biblical prohibition on such practices highlights the importance of distinguishing Israelite worship and practice from that of surrounding cultures.

Easton's Bible Dictionary “Easton's Bible Dictionary: Cutting — The flesh in various ways was an idolatrous practice, a part of idol-worship (Deut. 14:1; 1 Kings 18:28). The Israelites were commanded not to imitate this practice (Lev. 19:28; 21:5; Deut. 14:1). The tearing of the flesh from grief and anguish of spirit in mourning for the dead was regarded as a mark of affection (Jer. 16:6; 41:5; 48:37). Allusions are made in Revelation (13:16; 17:5; 19:20) to the practice of printing marks on the body, to indicate allegiance to a deity. We find also references to it, through in a different direction, by Paul (Gal. 6; 7) ”

Babylonian Talmud (Jewish (Rabbinic)) “Babylonian Talmud, Zevachim 97b.2: One might have thought that if the sin offering touched part of a piece of something that absorbed flavor from the sin offering, the entire piece should become disqualified. To counter this, the verse states: “Whatever shall touch its flesh shall be sacred” (Leviticus 6:20), to teach that only the section that touches the sin offering is disqualified. How so? What can be done with an item when a section of it is disqualified? One slices off the section of the piece that absorbed the disqualified matter. Additionally, the verse states: “Whatever shall touch it”
CCEL (Reformed (Old Princeton)) “Charles Hodge, Systematic Theology, Vol. 2, section 103: the law. The victim bore the sin of the offerer, and died in his stead. An expiation was thereby effected by the suffering of a vicarious punishment. This also determines the nature of the work of Christ. If He was an offering for sin, if He saves us from the penalty of the law of God, in the same way in which the sin offering saved the Israelite from the penalty of the law of Moses, then He bore the guilt of our sins and endured the penalty in our stead. We may not approve of this method of salvation. The idea of the innocent bearing th”

Now in the matters of excision mentioned in the Torah there are three different expressions. One is that which states, that man shall be cut off; 446 Ibid. , Verses 4 and 9.

Hence a member of the human body is to be disposed of according as it is expedient for the body.
