The Sabbath & the Lord's Day
Saturday or Sunday — and what does the day require? Compare how six traditions keep the fourth commandment.

Review status: initial-release
“Remember the Sabbath day, to keep it holy” is the longest of the Ten Commandments, yet Christians disagree on which day it means and what keeping it requires. All six traditions agree the commandment’s substance — worship of God and rest from labor — endures, and all gather for worship on Sunday, the day of Christ’s resurrection. They differ on whether Sunday is the Sabbath “transferred,” on how strictly the day must be kept, and on what counts as breaking it: from Westminster’s detailed Sabbatarian code to Luther’s insistence that the day itself is a matter of order and the Word is what makes it holy.

All six traditions agree that the fourth commandment’s substance — worship of God and rest from labor — still stands, and all of them gather for worship on Sunday, the day of Christ’s resurrection. From there they part ways. Catholics and Orthodox teach that Sunday fulfills the Sabbath as the Lord’s Day, the weekly feast of the Resurrection — with Mass obligatory for Catholics. The Reformed hold the strictest view: Sunday is the Christian Sabbath, and the whole day is to be kept holy in worship and rest, with only works of necessity and mercy excepted. Lutherans teach that the commandment is about hearing God’s Word, not about a calendar day — the day itself is a matter of order, and no one may bind the conscience with Sabbath regulations. Baptists and Methodists keep the Lord’s Day for worship and rest according to the Christian’s conscience under Christ’s lordship. This page presents each church’s teaching in its own words.

| Orthodox | Sunday is the Lord’s Day and eighth day of resurrection joy; Saturday keeps a festal character, and the day is kept in worship, not legalism. |
| Lutheran | The Third Commandment is about the Word, not the calendar: Christians are not bound to Saturday, and the day itself is a matter of order. |
| Reformed | The Sabbath, changed to the first day, continues as the Christian Sabbath: the whole Lord’s Day kept holy, with necessity and mercy excepted. |
| Baptist | The first day is the Lord’s Day, a Christian institution for worship and devotion, kept according to conscience under Christ’s lordship. |
| Methodist | Sunday is the Lord’s Day of worship, rest, and mercy — a gift to be received with a good conscience, not a new legal code. |
