Oh boy...
by that logic marriage is too...Sabbath and marriage were instituted at about the same time and for the same people...
sabbath like woman was made for man...some sinners reject both...
I mean that as a Jew I understand that the Sabbath is for me. It is for us, all Israel. The Sabbath is a part of God's law, and as such it can be for anyone. Even those who are not Jews make the decision to obey God. You can choose to become Jewish, or you can obey God as a non-Jew. The Sabbath is for God's people. Not everyone observes the Sabbath, but you don't have to begin as a Jew or become a Jew to observe God's commands, even the Sabbath although you may choose to do so and you may. The Sabbath is a command or commandment of God for His people. This may be your observance of the commands of God, even the things of God, in observing the Sabbath, such as in going to a synagogue and hearing Torah read. Or you may rest from your labors or your work at home.
As for marriage, it is both good and should be held in high honor by all. Don't try to break up a marriage. Fornicators and adulterors God will judge. Marriage was set up by God. All of mankind, except for those who never get married, understand marriage as between a man and a woman, and that they should not commit adultery. Neither should a person who has never been married, is single, or is not married commit adultery. These are both commandments of God, to remember the Sabbath day to keep it holy, and to marry if God has it for you that you should marry, and to not commit adultery.
1 Timothy 4:1-3 1 Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;
2 Speaking lies in hypocrisy; having their conscience seared with a hot iron;
3 Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth.
