What Does Kyrios Mean in the Bible?

Written By Anthony Delgado

The Greek word Kyrios (“Lord”) sits at the center of New Testament language about God, Jesus, and Christian faith. It is more than a polite religious title. Kyrios carries the weight of authority, ownership, and worship. Understanding what Kyrios means in the Bible helps clarify who God is, who Jesus is, and what it means to confess, “Jesus is Lord.”

In everyday Greek, Kyrios described a man of superior status who had authority and could dispose of persons or things under his control. In religious contexts, Kyrios became a way of addressing gods with respect, and in time it functioned almost like a divine name. That background makes the biblical use of Kyrios both powerful and intentionally provocative.

Kyrios in Greek Culture: “Lord” as Power and Devotion

Before looking at the Bible, it helps to see how Kyrios functioned in the wider world.

In Greek and Greco-Roman life, Kyrios could describe:

  • A household master, who had authority over servants and property (cf. Jesus’ parables about “the master of the house,” Matthew 10:25; Luke 12:36).

  • A social superior, similar to “sir,” but with a real sense of control and responsibility.

  • A deity, especially in Hellenistic and Roman-era piety, where gods and goddesses were called kyrios or kyria (“lord” or “lady”), expressing personal devotion and dependence.

Kyrios was also used for kings and, eventually, for the Roman emperor. In some contexts, to call Caesar “Lord” was an acknowledgment of his supreme authority in the political order (cf. the contrast implied in Revelation 13 and Revelation 17:14; 19:16).

This cultural environment forms the backdrop for the Christian confession that Jesus is Kyrios, a claim that has both theological and political weight.

Kyrios in the Septuagint: The Lord Who Bears the Divine Name

The Septuagint (LXX), the ancient Greek translation of the Old Testament, is the bridge between Greek usage and New Testament theology. In the LXX, Kyrios is the primary way of rendering the divine name.

Key features of Kyrios in the LXX:

  • Kyrios replaces the divine name Yahweh.

    • Instead of writing or pronouncing the tetragrammaton (YHWH), the Greek text uses Kyrios.

    • This preserves the Jewish practice of saying “Adonai” (“Lord”) when reading the divine name.

  • Kyrios sometimes translates other “Lord” titles:

    • ʾAdon, ʾAdonai, ʾAdoni (“Lord, my Lord”) can all appear as Kyrios.

  • “Lord GOD” and the double-‘Lord’ problem:

    • When the Hebrew says “Adonai Yahweh,” translators faced the problem of “Lord LORD.”

    • To avoid this, English Bibles often render it “Lord GOD,” capitalizing GOD to indicate that Yahweh lies behind it (e.g., Ezekiel 39:25; Amos 7:1–2).

    • In Greek, both elements are still expressed with Kyrios, but the underlying Hebrew distinction remains important for theology.

Biblically, Kyrios speaks of God’s:

  • Universal rule: “The Lord of all the earth” (Joshua 3:11; Micah 4:13).

  • Heaven-and-earth sovereignty: “Lord of heaven and earth” (Psalm 115:15; echoed in Matthew 11:25; Acts 17:24).

  • Exclusive worship: “For great is the Lord, and greatly to be praised; he is to be feared above all gods” (Psalm 96:4–5).

In the Old Testament, then, Kyrios is not a vague spiritual label. It is the way the Greek Bible speaks of the covenant God of Israel—the one Creator and ruler of all things (Genesis 1:1; Isaiah 44:24; Jeremiah 10:10–12).

Kyrios and Jesus: How the New Testament Confesses “Jesus is Lord”

When the New Testament calls Jesus “Kyrios”, it pulls all that Old Testament weight into the identity of the crucified and risen Messiah. This is not a minor upgrade from “Teacher” to “Master”; it is a claim about divine status and saving authority.

1. Kyrios as respectful address during Jesus’ ministry

In the Gospels, many people address Jesus as Kyrios:

  • Disciples crying out in danger: “Lord, save us! We are perishing!” (Matthew 8:25).

  • Blind men seeking mercy: “Lord, let our eyes be opened” (Matthew 20:30–34).

  • A centurion who trusts his authority: “Lord, I am not worthy to have you come under my roof” (Matthew 8:8).

Sometimes Kyrios functions like “sir,” but in contexts of miraculous power, forgiveness, and salvation, the title begins to stretch toward worship (Luke 5:8; John 9:38).

2. Kyrios as resurrection confession

After the resurrection, Kyrios becomes the central confession of the church:

  • “God has made him both Lord and Christ, this Jesus whom you crucified” (Acts 2:36).

  • “If you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved” (Romans 10:9).

  • “No one can say ‘Jesus is Lord’ except in the Holy Spirit” (1 Corinthians 12:3).

When Thomas sees the risen Jesus, he exclaims, “My Lord and my God!” (John 20:28). Kyrios is no longer just respectful; it is the language of worship and recognition that Jesus shares in the divine identity.

3. One Kyrios versus many “lords”

In a world filled with “lords” and “gods,” the New Testament insists on a single ultimate Lord:

  • “For although there may be so-called gods in heaven or on earth—as indeed there are many ‘gods’ and many ‘lords’—yet for us there is one God, the Father… and one Lord, Jesus Christ” (1 Corinthians 8:5–6).

  • “One Lord, one faith, one baptism” (Ephesians 4:5).

Here the confession “one Lord, Jesus Christ” adapts the monotheistic language of Israel (“The Lord our God, the Lord is one,” Deuteronomy 6:4) to the risen Christ, without abandoning the Father. The Father remains God; the Son is confessed as Kyrios, sharing in God’s rule and receiving the worship that belongs to the Lord of Israel.

4. Kyrios and the day of the Lord

Old Testament “day of the Lord” language (Joel 2:31; Amos 5:18) is now tied to Christ’s return:

  • “The day of our Lord Jesus Christ” (1 Corinthians 1:8).

  • “The day of the Lord will come like a thief” (2 Peter 3:10).

  • “Come, Lord Jesus!” (Revelation 22:20).

Jesus as Kyrios is not only Lord now; he is the one before whom every knee will bow and every tongue confess “that Jesus Christ is Lord, to the glory of God the Father” (Philippians 2:10–11; echoing Isaiah 45:23).

Kyrios, Allegiance, and the Christian Life

Because Kyrios means “Lord,” the title shapes Christian discipleship in concrete ways.

1. Kyrios means total allegiance

Confessing Jesus as Kyrios involves:

  • Obedience: “Why do you call me ‘Lord, Lord,’ and not do what I tell you?” (Luke 6:46).

  • Exclusive loyalty: “You cannot serve God and money” (Matthew 6:24).

  • Whole-life submission: “Whether we live or whether we die, we are the Lord’s” (Romans 14:8).

Kyrios language is covenantal: believers belong to the Lord who bought them with his blood (1 Corinthians 6:19–20; Revelation 5:9–10).

2. Kyrios means comfort and assurance

Because Jesus is Kyrios:

  • Nothing can separate believers from his love (Romans 8:38–39).

  • He rules over rulers and powers (Ephesians 1:20–23; Colossians 2:15).

  • He is “Lord of lords and King of kings” (Revelation 17:14; 19:16).

The same title that confronts worldly claims to ultimate authority also anchors Christian hope. The Lord who reigns is the Lord who laid down his life and rose again.

3. Kyrios and mission

If Jesus is Kyrios, then:

  • The church announces “peace through Jesus Christ (he is Lord of all)” (Acts 10:36).

  • Every nation lies within the scope of his authority: “All authority in heaven and on earth has been given to me” (Matthew 28:18–20).

The Christian proclamation is not merely that Jesus is a wise teacher or spiritual option, but that Jesus is Kyrios—the risen Lord who calls all people to repentance and faith (Acts 17:30–31).
