"John Calvin believed the Sabbath was a type of spiritual rest, which was fulfilled in Christ. On the one hand, Calvin said that the sanctification of one day in seven is no longer binding. On the other hand, he maintained that the command to worship God privately and also publicly remains. In a sermon on Deuteronomy 5:12-14, Calvin preached that we are called to worship continually, “but because of our weaknesses, or rather, because of our laziness, it is necessary that one day be appointed.” He continued: “We are to dedicate the day entirely to him.”" ReformedResource
Calvin was wrong about the Sabbath---God is very clear about it--
Remember the sabbath day, to keep it holy.
Six days shalt thou labour, and do all thy work:
But the seventh day is the sabbath of the LORD thy God: in it thou shalt not
do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy
maidservant, nor thy cattle, nor thy stranger that is within thy gates:
Exodus 20:8-10
"God’s action is a pattern to man because He blessed and sanctified the seventh day. In Genesis 2:3 “resting” is a distinct action from “blessing” and “sanctifying.” If He had merely rested, His action would have had no relation to our daily life, in that it may have been a one time action. However, He blessed and sanctified it as well. John Owen argued that God blessed the seventh day by sanctifying it. The day had good added unto it in that God sanctified it to His own glory. “Sanctify” has the sense of setting something apart and dedicating it to God. God set the day apart from the other six days so that it might be dedicated to Him in a particular way. Since God is perfectly holy (or sanctified), this sanctification must relate to man and his activities on it. All of creation was to give glory to God at all times of every day. However, God sanctified the seventh day particularly for man, who was to dress the garden the other six days, and dedicate the seventh day exclusively to the worship of God." ReformedResource
