Q 116. What is required in the fourth commandment?
A. The fourth commandment requireth of all men the sanctifying or keeping holy to God such set times as he hath appointed in his Word, expressly one whole day in seven; which was the seventh from the beginning of the world to the resurrection of Christ, and the first day of the week ever since, and so to continue to the end of the world; which is the Christian sabbath,2 and in the New Testament called the Lord’s Day.3
“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.
Therefore the people of Israel shall keep the Sabbath, observing the Sabbath throughout their generations, as a covenant forever. It is a sign forever between me and the people of Israel that in six days the Lord made heaven and earth, and on the seventh day he rested and was refreshed.’” (ESV)
“‘Observe the Sabbath day, to keep it holy, as the Lord your God commanded you. 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 or your male servant or your female servant, or your ox or your donkey or any of your livestock, or the sojourner who is within your gates, that your male servant and your female servant may rest as well as you.
And on the seventh day God finished his work that he had done, and he rested on the seventh day from all his work that he had done. So God blessed the seventh day and made it holy, because on it God rested from all his work that he had done in creation.
1 Corinthians 16:1-2
16:1 Now concerning the collection for the saints: as I directed the churches of Galatia, so you also are to do. 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.
On the first day of the week, when we were gathered together to break bread, Paul talked with them, intending to depart on the next day, and he prolonged his speech until midnight.
On the evening of that day, the first day of the week, the doors being locked where the disciples were for fear of the Jews, Jesus came and stood among them and said to them, “Peace be with you.”
Eight days later, his disciples were inside again, and Thomas was with them. Although the doors were locked, Jesus came and stood among them and said, “Peace be with you.”
“Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished.
Blessed is the man who does this,
and the son of man who holds it fast,
who keeps the Sabbath, not profaning it,
and keeps his hand from doing any evil.”
For thus says the Lord:
“To the eunuchs who keep my Sabbaths,
who choose the things that please me
and hold fast my covenant,
“And the foreigners who join themselves to the Lord,
to minister to him, to love the name of the Lord,
and to be his servants,
everyone who keeps the Sabbath and does not profane it,
and holds fast my covenant—
these I will bring to my holy mountain,
and make them joyful in my house of prayer;
their burnt offerings and their sacrifices
will be accepted on my altar;
for my house shall be called a house of prayer
for all peoples.” (ESV)
I was in the Spirit on the Lord’s day, and I heard behind me a loud voice like a trumpet (ESV)
