Reformed church view

The Reformed, or Covenant Theology view is similar to the Roman Catholic view. It holds that under the new covenant, the Mosaic Law fundamentally continues, but that parts of it have "expired" and are no longer applicable.The Westminster Confession of Faith (1646) divides the Mosaic laws into three categories: moral, civil, and ceremonial. In the view of the Westminster divines, only the moral laws of the Mosaic Law, which include the Ten Commandments and the commands repeated in the New Testament, directly apply to Christians today.
Ceremonial laws, in this view, include the regulations pertaining to ceremonial cleanliness, festivals, diet, and the Levitical priesthood. While the view affirms the Sabbath like the Roman Catholic view, some advocates hold that the Commandment concerning the Sabbath was redefined by Jesus (Matthew 12:1–13, Luke 13:10–17). In a revival of ideas established in the Puritan period, starting in the 1970s and 1980s, a branch of Reformed theology known as Christian Reconstructionism argued that the civil laws as well as the moral laws should be applied in today's society (a position called Theonomy) as part of establishing a modern theonomic state.
Advocates of this Reformed view hold that, while not always easy to do and overlap between categories does occur, the divisions they make are possible and supported based on information contained in the commands themselves; specifically to whom they are addressed, whom or what they speak about, and their content. For example, a ceremonial law might be addressed to the Levites, speak of purification or holiness and have content which could be considered as a foreshadowing of some aspect of Christ's life or ministry.
In keeping with this, most advocates also hold that when the Law is spoken of as everlasting, it is in reference to certain divisions of the Law. Some advocates, usually Theonomists, go further and embrace that idea that the whole Law continues to function, contending that the way in which Christians observe some commands has changed but not the content or meaning of the commands. (For example, they would say that the commands regarding Passover were looking forward to Christ's sacrificial death and the Communion mandate is looking back on it, the former is given to the Levitical priesthood and the latter is given to the priesthood of all believers, but both have the same content and meaning.)
