Continental Europe such as the Heidelberg Catechism, which emphasize rest and worship on the Lord's Day, but do not explicitly forbid recreational activities. However, in practice, many continental Reformed Christians also abstain from recreation on the Sabbath, following the admonition by the Heidelberg Catechism's author Zacharaias Ursinus that "To keep holy the Sabbath, is not to spend the day in slothfulness and idleness". Though first-day Sabbatarian practice declined in the 18th century, the First Great Awakening in the 19th century led to a greater concern for strict Sunday observance. The founding of the Day One Christian Ministries in 1831 was influenced by the teaching of Daniel Wilson. Common theology Many Christian theologians believe that Sabbath observance is not binding for Christians today, citing for instance Colossians 2:16-17. Some Christian non-Sabbatarians advocate physical Sabbath rest on any chosen day of the week, and some advocate Sabbath as a symbolic metaphor for rest in Christ; the concept of Lord's Day is usually treated as synonymous with "Sabbath". This non-Sabbatarian interpretation usually states that Jesus's obedience and the New Covenant fulfilled the laws of Sabbath, the Ten Commandments, and the Law of Moses, which are thus considered not to be binding moral laws, and sometimes considered abolished or abrogated. While Sunday is often observed as the day of Christian assembly and worship, in accordance with church tradition, Sabbath commandments are dissociated from this practice. Non-Sabbatarian Christians also cite 2 Corinthians 3:2-3, in which believers are compared to "a letter from Christ, the result of our ministry, written ... not on tablets of stone but on tablets of human hearts"; this interpretation states that Christians accordingly no longer follow the Ten Commandments with dead orthodoxy ("tablets of stone"), but follow a new law written upon "tablets of human hearts". In 3:7-11 we read that "if the ministry that brought death, which was engraved in letters on stone, came with glory ..., will not the ministry of the Spirit be even more glorious? ...And if what was fading away came with glory, how much greater is the glory of that which lasts!" This is interpreted as teaching that New Covenant Christians are not bound by the Mosaic Law, and that Sabbath-keeping is not required. Further, because "love is the fulfillment of the law," the new-covenant "law" is considered to be based entirely upon love and to rescind Sabbath requirements. Methodist theologian Joseph D.
