Topical Lexicon
Overview

The noun βλασφημία (Strong’s 988) gathers every form of speech that reviles the character, reputation, or majesty of God and, by extension, defames or slanders fellow image-bearers. Ranging from careless insults to conscious repudiation of divine truth, it appears eighteen times in the Greek New Testament and functions as a moral and theological marker that separates holiness from profanity.

Roots in the Old Covenant

Israel first heard the gravity of blasphemy in Leviticus 24:15-16, where the penalty was death. The prohibition protected the covenant community from minimizing the LORD’s holiness and safeguarded social order, since to curse God was to undermine the entire moral fabric of the nation. This background stands behind every New Testament occurrence.

Patterns of New Testament Usage

1. Gospels: βλασφημία surfaces most often when Jesus’ opponents accuse Him of usurping divine prerogatives (Matthew 9:3; Mark 2:7; Luke 5:21; John 10:33) and when the Sanhedrin condemns Him (Matthew 26:65; Mark 14:64). Jesus, for His part, warns that “every sin and slander can be forgiven, but blasphemy against the Spirit will never be forgiven” (Matthew 12:31).
2. Pauline Corpus: Paul treats it as a sin of the unregenerate mind (Colossians 3:8) and an attitude that must be banished from the church’s common life (Ephesians 4:31). In 1 Timothy 6:4 it exposes doctrinal pride.
3. General Epistles: Jude 1:9 contrasts Michael’s restraint with those who “slander celestial beings,” underscoring how unbridled speech reveals rebellion.
4. Revelation: John’s Apocalypse describes governmental and religious powers that have “blasphemous names” (Revelation 13:1) and “opened its mouth to speak blasphemies against God, to slander His name and His dwelling” (Revelation 13:6). Blasphemy thus becomes a hallmark of end-time opposition to Christ.

Blasphemy Against the Son

The charge leveled against Jesus in the Synoptics shows how messianic claims were evaluated through the lens of Levitical law. By forgiving sins (Mark 2:5-7) and equating Himself with the Father (John 10:33), Jesus forced hearers to choose: either He truly shared divine identity or was guilty of capital offense. The resurrection vindicated His claims, exposing the real blasphemy as refusal to acknowledge Him.

Blasphemy Against the Holy Spirit

Matthew 12:31-32 and Mark 3:28-30 locate the unpardonable sin in attributing the unmistakable work of the Spirit to satanic power. It is not a single rash word but a settled verdict against the light, revealing a heart hardened beyond repentance.

Human-to-Human Slander

While the primary object is often God, the term also covers malicious talk against people. Paul lists it with “anger, rage, malice” (Colossians 3:8), teaching that any speech that destroys another’s good name violates the Creator whose image that person bears.

Eschatological Blasphemy

Revelation portrays a crescendo: political beasts and Babylonian religion spew blasphemy until divine judgment silences them (Revelation 17:3). This anticipates the consummation, when every tongue will confess Jesus as Lord rather than curse His name.

Legal and Cultural Frame

First-century Jewish law treated divine blasphemy as capital, yet Roman jurisprudence generally ignored it unless it threatened public order. This tension explains why Jewish leaders pressed Pilate for Jesus’ execution on blasphemy grounds while couching it as treason (John 19:7-12).

Pastoral and Ministry Implications

• Guard the tongue: “Let no unwholesome talk come out of your mouths” (Ephesians 4:29-31).
• Protect God’s honor: Worship and preaching must present His name with reverence, avoiding flippant or manipulative references.
• Contend for truth: False teaching that denigrates Christ or the gospel is a form of blasphemy requiring corrective discipline (1 Timothy 6:3-5).
• Foster forgiveness: Because most blasphemies can be forgiven, proclaim grace to repentant sinners while warning of the peril of persistent hard-heartedness.

Contemporary Application

In an age where speech is instant and global, believers must weigh every word—digital or spoken—against the glory of God. Upholding His name involves both defending biblical revelation in public discourse and modeling gracious speech in private relationships.
