Christ, as the Creator of the seventh-day Sabbath, is rightly claiming to be the owner of that day, as reflected in the Greek word *kurios*, which means Lord, master, or owner, signifying possession and authority over property. In Mark 2:28 and Luke 6:5, He declares Himself as Lord of the Sabbath, affirming His authority over it. Nowhere in the New Testament does He relinquish ownership of the Sabbath or trade it for another day, maintaining His position as its master and creator.

In addressing Sapphira, Peter uses the term "Lord" from the Greek *kurios*, meaning master or lord, in Acts 5:9 when he asks, "How is it that you have agreed together to test the Spirit of the Lord?" In this context, the Holy Spirit is depicted as the possession of God, indicating that Ananias and Sapphira attempted to deceive God, who is present through His Spirit. Peter's use of *kurios* underscores the authority and mastery of God over His Spirit, emphasizing that their sin was ultimately against Him.

The term *kurios* (G2962) is significant in understanding the inspired usage of divine names and titles in the New Testament. The Scriptures were originally written in the Greek language, inspired by the living Word of God, Jesus Christ, through the Holy Spirit. By this inspiration, the names and titles of Jesus and of God were written in Greek, not Hebrew. Furthermore, many New Testament passages quote or cite the Old Testament, and wherever those passages contained the names or titles of God, the Holy Spirit inspired them to be recorded in Greek within the New Testament. This demonstrates that the use of Greek terms like *kurios* for divine names and titles is consistent with divine inspiration, affirming their sacredness in the language in which they were written.

The English word "church" descends from an Old English word "cirice," related to an Old High German word "kirihha." Both originate from the Late Greek "kuriakon," derived from the Greek "kuriakos," the possessive form of "kurios," meaning "lord." Thus, "kuriakos" translates to "lord's," indicating possession or belonging to the lord. It can refer to anything that belongs to the Lord. In the New Testament, the apostles used "kuriakos" only twice, in I Corinthians 11:20 as "Lord's supper" and in Revelation 1:10 as "Lord's day," with neither instance referencing the concept of church. Instead, the apostles predominantly used the term "ekklesia" to convey a different, more specific meaning related to assembly and calling, distinct from the possessive connotation of "kurios."
