Why Do Christians Worship on Sunday?

From creation onward, the people of God worshiped on the seventh day of the week. This was a “creation ordinance” that the Creator Himself established by His example, with the intent that His creatures would follow it. He worked six days and called His image-bearers to work (Gen. 2:15); He rested on the seventh day (Gen. 2:2; Ex. 20:11; 31:17) and called His image-bearers to rest. He signified this with His benediction, setting apart the seventh day as “holy” (Gen. 2:3)....

When Jesus rose from the dead on the first day of the week, things changed. Christ, the second Adam, “finished” (John 19:30) the work that the first Adam failed to do (Rom. 5:12-19). Because of that pivotal event, the church determined that for Christians under the new covenant, the day of worship and celebration of the Lord’s grace in Jesus Christ was to be the first day of the week, Sunday: “From the beginning of the world to the resurrection of Christ, [the Sabbath] was the last day of the week; and, from the resurrection of Christ, was changed into the first day of the week, which, in Scripture, is called the Lord’s day, and is to be continued to the end of the world, as the Christian Sabbath” (WCF, 21:7). On this day, we are reminded of and participate in the glorious reality that we have already entered God’s rest (Matt. 11:28; Heb. 4:10) and that we await the experience of the fullness of this rest in eternity in the new heavens and new earth (Rev. 21-22). We now assemble corporately for worship and enjoy a foretaste of our eternal rest, then go out into the kingdom of this world to work for six days. So why do we worship on Sunday and not Saturday?
