The Lord’s Day

International Sunday School Lesson February 15, 2026

Today’s lesson is for February 15, 2026. The scripture for today is Exodus 20:8-11, Romans 14:4-6, and Revelation 1:10. The title of today’s lesson is, “The Lord’s Day.” We’re covering a controversial subject in today’s lesson. What day do we go to church? Can we work on that day? Can we cook on that day? Is there a difference between the Sabbath and the Lord’s Day? Should we fall-out with folks if they disagree with us about church day?

Commanded Careful Rest

The Jewish community has always observed the Sabbath. That’s the 7th day of the week. That’s Saturday as we ALL learned in kindergarten.

Exodus 20:8–11 (ESV) ““Remember the Sabbath day, to keep it holy. Six days you shall labor, and do all your work, but the seventh day is a Sabbath to the Lord your God. On it you shall not do any work, you, or your son, or your daughter, your male servant, or your female servant, or your livestock, or the sojourner who is within your gates. For in six days the Lord made heaven and earth, the sea, and all that is in them, and rested on the seventh day. Therefore the Lord blessed the Sabbath day and made it holy.”

The Jews had clear instructions to keep the Sabbath after their deliverance from Egypt. It was a sign of the covenant between God and them. God told Moses in Exodus 31:13 ““You are to speak to the people of Israel and say, ‘Above all you shall keep my Sabbaths, for this is a sign between me and you throughout your generations, that you may know that I, the Lord, sanctify you.” The Jewish race has a special covenant with God. The Sabbath observance signifies that relationship and their deliverance as stated in Deuteronomy 5:15 “You shall remember that you were a slave in the land of Egypt, and the Lord your God brought you out from there with a mighty hand and an outstretched arm. Therefore the Lord your God commanded you to keep the Sabbath day.” . The Sabbath is the only one of the ten commandments that is not repeated in the New Testament.

Conviction-Filled Freedom

Now we come to the big question of how do we behave with others that think differently about which day is church day.

Romans 14:4–6 (ESV) “Who are you to pass judgment on the servant of another? It is before his own master that he stands or falls. And he will be upheld, for the Lord is able to make him stand. One person esteems one day as better than another, while another esteems all days alike. Each one should be fully convinced in his own mind. The one who observes the day, observes it in honor of the Lord. The one who eats, eats in honor of the Lord, since he gives thanks to God, while the one who abstains, abstains in honor of the Lord and gives thanks to God.”

The clear instructions given from God through Paul is to not sweat the little things. Some things should be left to the individual. Now, I’m not talking about clear things like stealing and fornication. The day you go to church is really a matter of preference. Don’t sweat the little things. Before we leave the subject though, let me refute some incorrect historical information. Sunday worship was NOT started by Constantine in 321 A.D. The Lord’s Day worship, Sunday, was practiced way before Constantine. Ignatius who lived from 30-107 A.D. wrote about Sunday worship, Justin Martyr born in 110 A.D. wrote about Sunday worship, Tertullian born 145 A.D. wrote about Sunday worship, The Teachings of the Apostles, written in 105 A.D. contains a discussion of Sunday worship, Irenaeus argued against keeping Jewish sabbaths in 178 A.D., Clement of Alexandria argued against keeping the sabbath in 174 A.D., Origin around 200 A.D. argued to keep Sunday instead of the sabbath, and the list goes on. The only thing I would vigorously contradict someone about is if they try to say keeping Sunday as the Lord’s day was introduced by Constantine to include pagan worship to apostate Christianity. It is just historically incorrect and gives rise to some odd beliefs about sections of the body of Christ.

Christ’s Completed Rest

We now see the one time Sunday is called the Lord’s day in scriptures.

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

John was worshipping on Sunday.
