What is Blasphemy?

Blasphemy, at its core, refers to showing irreverence, disrespect, or contempt toward God, sacred things, or religious beliefs. It’s not just about spoken words; it can include thoughts, actions, or attitudes that dishonor the divine. The English word “blasphemy” comes from the Greek blasphēmia, meaning “evil-speaking” or “slander.”

In most religious traditions—Judaism, Christianity, and Islam—blasphemy is considered a serious offense because it directly dishonors God. While the exact definitions vary, the common thread is a willful disregard for God’s holiness.

What is Blasphemy in the Bible?

The Bible treats blasphemy as a grave sin.

Old Testament (Hebrew Bible):
In Leviticus 24:16, God commanded that “anyone who blasphemes the name of the Lord is to be put to death.” This reflects the seriousness with which Israel’s law treated irreverence toward God.
New Testament:
Jesus confronted accusations of blasphemy multiple times, particularly when He claimed divine authority (Matthew 9:3; John 10:33). In these cases, religious leaders thought He was dishonoring God by equating Himself with Him—but from the Christian perspective, Jesus was telling the truth.

Blasphemy in the biblical sense often goes beyond casual insults; it’s a conscious act of denying or insulting God’s nature and work.

What is Blasphemy Against the Holy Spirit / Holy Ghost?

One of the most discussed and sometimes misunderstood teachings of Jesus concerns blasphemy against the Holy Spirit.

In Matthew 12:31-32, Jesus says:

“And so I tell you, every kind of sin and slander can be forgiven, but blasphemy against the Spirit will not be forgiven. Anyone who speaks a word against the Son of Man will be forgiven, but anyone who speaks against the Holy Spirit will not be forgiven, either in this age or in the age to come.”

This is echoed in Mark 3:28-30 and Luke 12:10.

Definition in context:
Blasphemy against the Holy Spirit refers to a deliberate, hardened rejection of the Spirit’s work—especially attributing the works of God to Satan. In the Gospels, this statement by Jesus was prompted when the Pharisees claimed that His miracles, done by the power of the Holy Spirit, were actually powered by demons.

What is Considered Blasphemy Against the Holy Spirit?

Theologians generally agree that blasphemy against the Holy Spirit is not a one-time careless remark but a persistent, willful rejection of God’s truth and grace.

It can be understood as:

Attributing God’s work to Satan – as the Pharisees did in Matthew 12.
Deliberately resisting the Holy Spirit’s conviction – refusing to repent even when truth is clear.
Final hardening of the heart – rejecting salvation until death, leaving no room for forgiveness because repentance never happens.

This is why it is called “unforgivable” — not because God’s mercy has limits, but because the person has closed themselves off completely from accepting it.

What is the Blasphemy of the Holy Spirit?

While “blasphemy against” and “blasphemy of” the Holy Spirit are often used interchangeably, both point to the same concept: willfully insulting, rejecting, or misrepresenting the Spirit’s divine work.

Key points:

It’s not accidental—it’s a knowing act.
It’s not ordinary doubt—doubt can be resolved with faith.
It’s not a single angry outburst—but a settled attitude against God’s truth.

Examples of Blasphemy

Biblical Examples:

Pharisees accusing Jesus of casting out demons by Beelzebul (Matthew 12:24).
The stoning of Stephen in Acts 7—Stephen was accused of blasphemy for speaking about Jesus.
Nebuchadnezzar’s arrogance (Daniel 4)—though he later repented, his initial pride dishonored God.

Historical Examples:

Early Roman emperors demanding worship as gods.
Persecutors mocking and killing Christians for their faith.

Modern Examples (in a Christian sense):

Claiming the Bible’s truth is evil or inspired by Satan (when done knowingly).
Mocking Jesus or the Holy Spirit in a deliberate, hostile way.
Rejecting the Spirit’s conviction over a lifetime.

Why Blasphemy Against the Holy Spirit is Unique

Most sins—lying, stealing, even denying Christ in a moment of fear—can be forgiven if a person repents. Peter denied Jesus three times but was restored (John 21:15-17).

Blasphemy against the Holy Spirit is different because it represents a heart that refuses repentance entirely. If someone permanently rejects God’s offer of forgiveness, they leave themselves no path to salvation.

This is why Jesus warns so strongly about it—not to scare those who have doubts, but to alert people to the danger of willfully opposing the Spirit’s work.

Common Misunderstandings

Fear you’ve committed it unintentionally?
If you’re worried about committing this sin, that itself is evidence you haven’t. Those who commit it don’t care about repentance.
Accidental words or jokes?
While careless words about God are wrong, they are forgivable if confessed and turned from.
Mental struggles or intrusive thoughts?
These are not the same as deliberate blasphemy. Temptation itself is not sin; acting on it willfully is.

Conclusion

Blasphemy, in its broadest sense, is disrespect toward God and holy things. In the Bible, blasphemy against the Holy Spirit stands out as the “unforgivable sin” because it reflects a deliberate, final rejection of God’s truth and grace. It’s not about making a mistake or having doubts—it’s about persistently refusing the Spirit’s conviction and calling good “evil.”

The message is sobering, but it’s also filled with hope: anyone who turns to God in repentance can be forgiven. The danger lies not in God’s unwillingness to forgive, but in our unwillingness to accept His forgiveness.
