Rome first destroyed Jerusalem in 70 A.D.
Then in 365 A.D. it abolished the resting on Sabbath. (See PDF.)
Yet, it was one of the Ten Commandments.
For those Christians who obey this command, here is a Sabbath meditation.

Isaiah 58:13-14 “If thou turn away thy foot [on] the sabbath, from doing thy pleasure...not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words: [that] thou shalt delight in Jehovah...I will make thee to ride upon the high places of the earth; and I will feed thee with the heritage of Jacob thy father: for the mouth of Jehovah hath spoken it.”
