The resurrection of Jesus inaugurated one of the most remarkable changes in human religious observance – Sunday became the day of the week for Christian worship. Up to that point in history, Sunday was just another day in the week, a day for work, commerce, and , if you were wealthy enough, pleasure. But Christians made Sunday “the Lord’s Day,” determined to celebrate the Messiah’s resurrection and humanities’ salvation. And this happens first in the Jewish context – something even more astonishing given its commitments to Sabbath and the seventh day of the week.
Naming Sunday “the Lord’s Day” connects it with the “day of the Lord”, an expression found frequently in the Old Testament. The “day of the Lord” marked Yahweh’s incursion into history for salvation or judgment. The resurrection of Jesus Messiah and his ascension demonstrated God’s new action to re-create his people. Sunday, the day of Jesus’ resurrection, is a constant reminder of God’s gracious intervention in Christ, a celebration of our new hope in Christ, and an affirmation of our expectation the Christ will return for the final “Day of the Lord.”
When Christians gathered on Sunday, they made a statement about their identity and the nature of their Messianic community. Jesus is Lord, our Lord! We are his people, his church! We are the demonstration plot of God’s Kingdom rule – chosen race, priestly kingdom, holy nation, God’s special people!
But Sunday also marks a fundamental change in the way Christians understand their lives. By making their affirmations about Jesus and their relationship to him on the “first day of the week,” Christians declare that this is the foundation for all of the ensuing days of the week. Sunday sets the stage for the entire week to become the opportunity to worship God and exalt Jesus in all that they do – in the household, in the marketplace, in the civic community. Sunday is not the end of the week, it is the beginning.
Further, by celebrating on this day, Christians declare that God’s Sabbath rest now envelopes their whole lives. Every day is Sabbath because salvation is secure in Christ, God’s Spirit is resident within, and their whole lives become a continual sacrifice to God. All of life is worship. Jesus offered “rest for our souls” and as the author of Hebrews explains, we have entered into our rest in Christ (Hebrew 4).
When believers understand this significant shift created by the resurrection of Jesus, it sets life within an entirely new frame of reference. Monday to Saturday become the setting for our “ministries,” i.e. the opportunity to be Kingdom agents for God in the workplace, our families and our communities. Sunday’s equip us and remind us of our fundamental allegiance to God and the great Kingdom project He has invited us to participate in.
