Did Constantine change the Sabbath? Did Constantine make the Sabbath Sunday instead of Saturday?

from the old testament

• In Genesis 2:2–3, God rested on the seventh day and blessed it. The Sabbath was rooted in creation itself—not in Roman law, political decree, or later church history.
• In Exodus 20:8–11, the Fourth Commandment clearly identifies the Sabbath as the seventh day, tied to God’s creation rest. It was part of the covenant given to Israel, not a flexible civil custom that could be altered by an emperor.
• The Old Testament consistently treats God’s law as unalterable (see Deuteronomy 4:2). The Sabbath command came from God Himself. No king of Israel had authority to redefine it—let alone a Roman emperor centuries later.

from the new testament

• Believers had long been gathering on the first day of the week before Constatine’s decree. Acts 20:7 records Christians gathering “together to break bread” “on the first day of the week.”
• Paul also instructed the Corinthians, “On the first day of every week, each of you is to put something aside and store it up, as he may prosper, so that there will be no collecting when I come” (1 Corinthians 16:2). That comment assumes that it was normal for believers to meet on that day of the week.
• The church was never bound by the Sabbath, which was a day specifically given to Israel. Paul wrote that “one person esteems one day as better than another, while another esteems all days alike” (Romans 14:5).
• Paul also advised believers in Colossae, “Therefore let no one pass judgment on you in questions of food and drink, or with regard to a festival or a new moon or a Sabbath. These are a shadow of the things to come, but the substance belongs to Christ” (Colossians 2:16–17). Christians were not required to observe particular days as holy in the manner Israel once did. Because the Sabbath command belonged to Israel’s covenantal life, the church was free to gather on any day, and the first day naturally grew out of the centrality of the resurrection in the Christian life.

implications for today

Depending on what it is, we might want the credit or want to avoid the blame. Constantine either gets credit for his decree requiring rest on Sunday or blame from those who believe Christians today should observe Old Testament sabbatarian law.

But crediting or blaming Constantine misses the point: Christians today are no longer bound by Old Testament civil and ceremonial laws. Christ is our Sabbath-day rest (Hebrews 4:1-11). The pattern we follow is that of the early church, who gathered on Sundays to remember that Christ rose on that day. Those who would like to take a regular Sabbath do so not because we are required but because it is a helpful rhythm for them to remember that we can rest when we trust that God is in control and sovereign over all. We must all remember this, but having a Sabbath is helpful in reminding us regularly.

Believers should not judge one another about the day we meet (Romans 14:5; Colossians 2:16-17). When we gather is not as important as that we gather (Hebrews 10:25). But Sunday is the pattern, and in most societies, Sunday is when most people do not work, so more people can meet on that day.

God has given us a body of believers to encourage each other and bear each other’s burdens (Galatians 6:2). May we focus on His mercy and love in doing that and not argue about the “proper” days to meet.
