The Divine Name: LORD in Capital Letters
When Bible readers encounter "LORD" in small capitals in most English translations, they are seeing a representation of God's personal covenant name, the four Hebrew letters YHWH (often rendered Yahweh). This name was revealed to Moses at the burning bush when God said, "I AM WHO I AM" (Exodus 3:14), connecting the name to the Hebrew verb of being. It signifies God's self-existence, eternal nature, and faithfulness to His promises.
This name appears over 6,800 times in the Hebrew Old Testament, making it by far the most frequent designation for God in Scripture. It is the name associated with God's covenant relationship with Israel: "I am the LORD your God, who brought you out of Egypt, out of the land of slavery" (Exodus 20:2). Every time a reader encounters "LORD" in capitals, the text is using this deeply personal, covenant name.
Adonai: Lord as Master and Sovereign
The Hebrew title Adonai, meaning "my Lord" or "my Master," represents a different aspect of God's character. While YHWH emphasizes God's personal, covenant identity, Adonai emphasizes His authority, sovereignty, and right to command. This title appears frequently in the prophets, often in the combination "Lord GOD" (Adonai YHWH), which brings together both the sovereign authority and the covenant faithfulness of God (Isaiah 61:1; Ezekiel 2:4).
Adonai has a fascinating history in Jewish practice. Out of reverence for the divine name YHWH, Jewish readers began substituting Adonai whenever they encountered the four sacred letters in the text. This practice, rooted in an interpretation of Leviticus 24:16 that warned against misusing God's name, became universal in Jewish worship and reading. As a result, the two titles became intertwined in tradition, even though they carry distinct meanings.
Lord in the New Testament: Kurios
The Greek word Kurios, meaning "lord" or "master," is the most important title applied to Jesus in the New Testament. It is also the word the Greek translation of the Old Testament (the Septuagint) used to render both YHWH and Adonai. This creates a powerful theological connection: when the New Testament calls Jesus "Lord," it uses the same word that stands for the divine name in the Greek Old Testament.
The confession "Jesus is Lord" became the earliest and most fundamental Christian creed (Romans 10:9; 1 Corinthians 12:3). Paul declares that God exalted Jesus and gave Him "the name that is above every name, that at the name of Jesus every knee should bow" and "every tongue acknowledge that Jesus Christ is Lord" (Philippians 2:9-11). This passage deliberately echoes Isaiah 45:23, where YHWH declares that every knee will bow to Him — applying the language of the one true God to Jesus.
The apostles repeatedly apply Old Testament YHWH texts to Jesus. Joel 2:32, "Everyone who calls on the name of the LORD will be saved," is cited by Peter at Pentecost with reference to Jesus (Acts 2:21, 36). Thomas' confession, "My Lord and my God" (John 20:28), represents the fullest expression of this identification.
Other Uses of "Lord" in Scripture
Beyond its theological uses, "lord" appears in Scripture as a term of respect and authority in human relationships. Sarah called Abraham "lord" (Genesis 18:12; 1 Peter 3:6). Servants addressed their masters as "lord." The title could refer to kings, rulers, and other figures of authority. The Aramaic word for lord appears in the book of Daniel, used both for God (Daniel 2:47; 5:23) and for human authorities (Daniel 4:24).
Another Greek word, meaning "master" or "despot," is used more rarely and appears only of God and the exalted Christ in the New Testament (Luke 2:29; Acts 4:24; 2 Peter 2:1; Revelation 6:10). This term emphasizes absolute ownership and authority.
Reading "Lord" with Understanding
For modern Bible readers, paying attention to how "Lord" is printed in their translation reveals important theological content. "LORD" (all capitals) signals the covenant name YHWH. "Lord" (standard capitalization) typically represents Adonai or Kurios as a title of authority. "lord" (lowercase) may refer to human masters or authorities.
This is more than a typographical convention. It preserves the distinction between God's personal name — His identity as the eternal, self-existent, covenant-keeping God — and His title as sovereign master of all creation. Both dimensions are essential for understanding who God is and how He relates to His people. The New Testament's application of both dimensions to Jesus Christ represents one of the most profound theological claims in all of Scripture: that in Jesus, the covenant God of Israel has come in person.
Biblical Context
The title Lord appears throughout the entire Bible. YHWH dominates the Old Testament from its revelation at the burning bush (Exodus 3:14) through the prophets. Adonai appears frequently in prophetic literature. In the New Testament, Kurios is applied to Jesus from the earliest confessions (Romans 10:9) through the final vision of Revelation (Revelation 22:20-21). The interplay between these terms spans both testaments and is central to biblical theology.
Theological Significance
The title Lord reveals God's identity as both personally present in covenant relationship (YHWH) and sovereignly authoritative over all creation (Adonai). The New Testament's application of Lord to Jesus Christ is the foundation of Christian Christology, claiming that Jesus shares the identity and authority of Israel's God. The confession 'Jesus is Lord' is the earliest Christian creed and carries implications for every area of life and worship.
Historical Background
The practice of substituting Adonai for YHWH in Jewish reading developed during the Second Temple period, likely out of reverence for the divine name. The Greek Septuagint translated both YHWH and Adonai as Kurios, which became the bridge term that allowed New Testament authors to apply Old Testament YHWH texts to Jesus. The Gallio inscription and other Roman-era evidence shows that calling Jesus 'Lord' in the first-century context implicitly challenged the claim of Caesar to that title, giving the confession a political as well as theological dimension.
