Topical Lexicon
Occurrences in the New Testament

Kuriakos appears only twice, each time setting apart something that is uniquely “of the Lord.” In Revelation 1:10 John writes, “I was in the Spirit on the Lord’s Day,” and in 1 Corinthians 11:20 Paul refers to believers gathering to eat “the Lord’s Supper.” Both contexts emphasize exclusive ownership by the risen Christ over time (a day) and over a covenant meal (the supper).

The Lord’s Day (Revelation 1:10)

“I was in the Spirit on the Lord’s Day, and I heard behind me a loud voice like a trumpet” (Revelation 1:10).

1. Christ-Centered Time. By calling the first day “Lord’s,” the text testifies that the resurrection forever stamped Sunday as belonging to Christ. It is not merely the first of seven equal days; it is the memorial of the new creation (John 20:1; 2 Corinthians 5:17).
2. Worship and Revelation. John’s visionary encounter comes while he is in communion with God on this day, suggesting an established practice of corporate worship and spiritual expectancy (Acts 20:7; Hebrews 10:25).
3. Continuity and Fulfillment. The Sabbath principle of dedicating time to God (Exodus 20:8–11) finds its fulfillment in celebrating Christ’s finished work and ongoing reign (Hebrews 4:9–10).

The Lord’s Supper (1 Corinthians 11:20)

“So then, when you come together, it is not the Lord’s Supper you eat” (1 Corinthians 11:20).

1. Covenant Meal. Instituted by Jesus on the night He was betrayed (Luke 22:19–20), the supper proclaims His death “until He comes” (1 Corinthians 11:26). By calling it “Lord’s,” Paul underscores divine ownership over both the elements and the fellowship.
2. Call to Unity and Holiness. The Corinthian abuses reveal that self-centered feasting turns the ordinance into something other than the Lord’s; discerning His body requires mutual care and self-examination (1 Corinthians 11:27–29).
3. Eschatological Anticipation. The meal looks forward to the marriage supper of the Lamb (Revelation 19:9), linking present remembrance with future glory.

Theological Themes

• Christ’s Sovereign Ownership – Whether a day or a meal, what is kuriakos is never at human disposal; it is consecrated to Christ’s rule (Romans 14:8–9).
• Resurrection and New Creation – Both usages flow from the resurrection: the first day memorializes it; the supper proclaims the death that leads to resurrection life (1 Peter 1:3).
• Covenant Community – Kuriakos marks corporate identity. Believers gather as one body (1 Corinthians 10:16–17) under one Lord (Ephesians 4:5).
• Eschatological Hope – The adjective pushes worshipers to look ahead: the Lord’s Day previews the eternal Day (2 Peter 3:10–13), and the Lord’s Supper previews the eternal banquet.

Historical Development in Church Practice

Early writers testify that the first Christians met on “the Lord’s Day” (Ignatius, Magnesians 9; Didache 14). Justin Martyr describes the church assembling “on the day called Sunday” for Scripture, prayer, and the Eucharist (Apology I, 67). The Latin translation dies dominica and later English “Sunday” carried the same reference to Christ. Constantine’s 321 decree, though civil in nature, reflects an already established Christian practice.

Similarly, the Lord’s Supper quickly became the central act of Lord’s Day worship. While liturgical expressions varied, the unchanging core remained remembrance of Christ’s sacrifice, thanksgiving, and anticipation of His return.

Ministry Applications Today

1. Guard the Day. Setting apart Sunday for worship, rest, and service answers the biblical call to honor what is “the Lord’s.”
2. Guard the Table. Faithful proclamation of the gospel, self-examination, and reconciliation preserve the supper’s sanctity.
3. Cultivate Expectation. John’s vision and Paul’s teaching invite believers to meet with Christ in Spirit-filled corporate gatherings.
4. Live Under Lordship. Recognizing time and table as His nurtures a lifestyle in which every sphere is joyfully surrendered to the risen Lord.

Related Biblical Parallels

Exodus 31:13 – Sabbaths “a sign…that you may know that I am the LORD who sanctifies you.”

Matthew 12:8 – “The Son of Man is Lord of the Sabbath.”

Acts 2:42 – “They devoted themselves…to breaking of bread and to prayer.”

Colossians 1:18 – “So that in everything He might have the supremacy.”

Kuriakos therefore serves as a concise, Spirit-inspired reminder that Christ’s lordship claims both the rhythm of worship and the centerpiece of remembrance, anchoring the church’s life between resurrection morning and the marriage supper yet to come.
