κύριος

The Greek word _kyrios_ has a broad semantic range, encompassing various shades of meaning from a polite form of address to a declaration of divine sovereignty. At its most basic, it refers to someone who holds power or is in charge, such as a master over servants or a property owner. This usage is common in the Gospels, where individuals address Jesus as “Lord” (e.g., Matt 24:45, Luke 7:6), acknowledging his authority or position, though not necessarily his divinity. The term can also be used for human rulers or even as a title of respect similar to “Sir.”

However, _kyrios_ takes on profound theological significance when applied to God. In the Septuagint, the Greek translation of the Old Testament, _kyrios_ is frequently used to translate the Hebrew divine name YHWH (the LORD). This connection is crucial for understanding the New Testament’s use of _kyrios_ for Jesus. When early Christians confessed Jesus as “Lord,” they were not merely calling him “master” but were ascribing to him divine authority and identity, placing him on par with God. This confession underscored their belief in Jesus’s role as the sovereign ruler and the object of worship, echoing the Old Testament’s portrayal of YHWH.

The theological weight of _kyrios_ is evident in passages that declare Jesus’s resurrection and exaltation, where God has made him both Lord and Christ. This culminates in the cosmic recognition that every knee will bow and every tongue confess that Jesus Christ is Lord, to the glory of God the Father. The use of _kyrios_ in this context highlights Jesus’s ultimate authority, his role in salvation, and his position as the supreme ruler of all creation, demanding worship and obedience from believers. The term thus moves from a common descriptor of human authority to a powerful affirmation of divine lordship.
