From the Heidelberg Catechism, for the Lord’s Day, September 22

The Fourth Commandment

“Remember the Sabbath day, to keep it holy. Six days you shall labor and do all your work, but the seventh day is the Sabbath of the LORD your God. In it you shall do no work: you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your cattle, nor your stranger who is within your gates. For in six days the LORD made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore the LORD blessed the Sabbath day and hallowed it.”

103. What does God require in the fourth Commandment?

In the first place, God wills that the ministry of the Gospel and schools be maintained, and that I, especially on the day of rest, diligently attend church to learn the Word of God, to use the Holy Sacraments, to call publicly upon the Lord, and to give Christian alms. In the second place, that all the days of my life I rest from my evil works, allow the Lord to work in me by His Spirit, and thus begin in this life the everlasting Sabbath.
