Calvin on Genesis 2:
Afterwards, in the Law, a new precept concerning the Sabbath was given, which should be peculiar to the Jews, and but for a season; because it was a legal ceremony shadowing forth a spiritual rest, the truth of which was manifested in Christ. Therefore the Lord the more frequently testifies that he had given, in the Sabbath, a symbol of sanctification to his ancient people. Therefore when we hear that the Sabbath was abrogated by the coming of Christ, we must distinguish between what belongs to the perpetual government of human life, and what properly belongs to ancient figures, the use of which was abolished when the truth was fulfilled.
Calvin was not a Sabbatarian like many of the puritans who hated Christmas.
