Are Grace Believers Required to Keep the Sabbath

      There is no doubt that at one time God required His people under the Old Testament Law to keep the Sabbath (Exodus 20:8-10).  There are professing Christians today who teach believers under grace must still keep the Sabbath.  Some even teach that God changed the Sabbath after the cross from Saturday to Sunday.  Many will even call Sunday the "Christian Sabbath," and they thus assume going to church on Sunday equates to fulfilling the command of Exodus 20 of keeping the Sabbath.  There is not one Bible verse that teaches that God changed the Sabbath to Sunday or that Sunday is the "Christian Sabbath."  All of this is nothing more than tradition of men.  In reality Exodus 20 says nothing about going to church on Saturday or Sunday.  Keeping the Sabbath simply meant doing no work.

     Under grace believers are not obligated to observe any day above any other day. Romans 14:5 KJV — One man esteemeth one day above another: another esteemeth every day alike. Let every man be fully persuaded in his own mind.

    Believers under grace are not to judge one another in regards to Sabbath days.  Colossians 2:16 KJV — Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days:

     Is the principle of resting from work one day a week something that can be applied voluntarily by grace believers?  Absolutely.  Even the "hyper" E W Bullinger taught this in his book "How to Enjoy the Bible" in Part One section IV (see part 2 (c) titled "As to the Sabbath").  Note the following quote from Bullinger's book:

"The Ceremonial Laws of the Sabbath were given to Israel, and not to the Gentile nations of the earth, Pagan or otherwise. While the interpretation therefore belongs to Israel, it would be wise for all nations to make an application of the great principle laid down in the Law, as to resting from servile labour on one day in seven."
