Why does Jesus ask the demon's name?
Why does Jesus ask the demon's name in Mark 5:9, and what is its significance?

Narrative Setting (Mark 5:1-13)

Jesus crosses the Sea of Galilee to the Gentile territory of the Gerasenes. Immediately a man “with an unclean spirit” meets Him (v. 2). The man’s violent strength, nakedness, and habitation among tombs dramatize the curse of death and separation from God. Jesus commands the spirit out; before leaving, He asks, “What is your name?” (v. 9).


The Ancient Power of Naming

In both Hebrew and Greco-Roman cultures, to ask a name was to assert relational and legal authority (cf. Genesis 2:19; Exodus 33:17; Acts 19:15). A disclosed name granted the inquirer ascendancy; secrecy preserved power. Jesus’ question clarifies that He—not the demons—governs the encounter.


Public Revelation of the Enemy’s Magnitude

“Legion” (Latin legio) described a Roman force of c. 6,000 soldiers. The reply “for we are many” (Mark 5:9) reveals:

• The possession is collective, explaining the man’s extraordinary bondage.

• Jesus’ authority extends over a vast demonic host, underscoring His divinity (Psalm 89:9; Colossians 2:15).

Luke preserves the plural “they begged Him” (Luke 8:31), confirming multiple spirits.


Instruction for Disciples in Deliverance Ministry

By extracting the name, Jesus models diagnostic clarity before deliverance (cf. Matthew 17:21). While demons’ names are not prerequisites for exorcism, exposure unmasks deception and prevents masquerade (2 Corinthians 2:11). The church fathers (e.g., Justin, Apol. 2.5) cite this passage to teach that demons, when confronted by Christ’s authority, must confess their identity.


Restoration of Human Identity

Possession had fragmented the man’s personhood; he speaks only through the demons (“we”). After deliverance he sits “clothed and in his right mind” (Mark 5:15). The narrative moves from legion to individual, illustrating salvation’s goal: the recovery of the imago Dei (Genesis 1:27; Ephesians 4:24).


Legal Overtones of Spiritual Warfare

The term “Legion” evokes imperial occupation. Jesus’ victory foreshadows His cosmic triumph over hostile powers (Ephesians 1:20-22). Demons’ subsequent request to enter swine (Mark 5:12) acknowledges His judicial right to assign their destination (Matthew 25:41).


Evangelistic Significance for the Decapolis

The healed man becomes the first commissioned Gentile evangelist: “Go home to your own people and tell them how much the Lord has done for you” (Mark 5:19). Declaring how “Legion” fell serves as apologetic proof to pagan audiences steeped in occult fear.


Archaeological Corroboration

Excavations at Kursi (identified with “Gergesa”) reveal 1st-century tombs on a lakeside cliff matching Mark’s topography. Gadara’s extensive pig industry is attested by Greco-Roman mosaics depicting swine, fitting the narrative’s herd of “about two thousand” (Mark 5:13).


Theological Emphasis on Christ’s Sovereignty

Mark 5 positions Jesus as the “stronger man” who plunders Satan’s house (Mark 3:27). His mere word overpowers thousands, anticipating His resurrection victory where He “disarmed the rulers and authorities” (Colossians 2:15).


Eschatological Foreshadowing

The demons’ fear of premature judgment (“torment us” Matthew 8:29) anticipates Revelation 20:10, where demonic forces meet final condemnation. Naming here previews the final roll call when every rebel will be exposed and sentenced.


Practical Application for Today

• Spiritual warfare is real; Christians engage it clothed in Christ’s authority (Ephesians 6:10-18).

• Identity in Christ overcomes the fragmented identities imposed by sin and demonic influence.

• Confession and exposure of darkness precede true freedom (1 John 1:7-9).


Summary

Jesus asks the demon’s name to assert His authority, unveil the scale of bondage, instruct disciples, restore human dignity, and publicly demonstrate His supremacy over the largest conceivable demonic force. The episode validates the historical Jesus’ power, strengthens confidence in Scripture, and proclaims the gospel’s capacity to liberate anyone enslaved by evil.
