In the beginning God gave man a day of rest, a day to worship Him.  Many believe it is Sunday, others Saturday, some say it doesn’t matter which day as long as we worship the Lord, if we worship Him in spirit and truth.  Which day did Christ and the Apostles observe?  Which day did Paul teach the Gentile converts to observe?  How and when did the day change from the seventh to the first day of the week?  Just what is the purpose of the Sabbath Day?  Does it make any difference which day we keep?

    Which day is the Sabbath, and does it really matter?  The first thing we need to do is look on the calendar and see which day is the seventh day and which day is the first day of the week.  You will notice that Sunday is the 1st day and Saturday is the 7th day.  According to the Lord He used the numbers 1-7, not our Roman names of each day of the week which were named after the Roman Gods and Goddesses.  Let’s look into the Scriptures and just see what the Bible says about the First day or the Seventh day for worship.

    We have been reared in the Sunday-observing world.  So, naturally, we have taken Sunday-observance for granite.  Naturally, the idea of a different day as the true day of worship would strike us as being absurd. 

    Yet, today some are telling us Saturday is the right day.  They insist the seventh day is the only day the Bible anywhere commands us to keep for 24 hours, from Friday sunset to Saturday sunset, 24 hours. 

    But others claim that the Sabbath was done away with, nailed to the cross (Colossians 2:14), and it is Jewish, and Sunday became the Christian Sabbath because Christ was resurrected on Sunday morning (Mark 16:2).

    We must be willing to be corrected, if wrong.  We must be careful not to “be blown about with every wind and doctrine” (Ephesians 4:14).  We must free our mind of all prejudice and accept what is the true day of worship, Saturday are Sunday.

    We must be able and willing to study both sides honestly, laying aside our ideas and desire, prayerfully asking God for guidance.  Just who is right?  Honest investigation of the Scriptures will confirm what and who is right (2 Timothy 2:15).

    If we are wrong, we should want to know it, and if we are right, regardless if it Saturday are Sunday, we should be ready to change to please God.  If we are wrong, we should want to know it, and we should quickly and willingly accept the truth as God reveals it to us (John 8:32).

    The word Sunday or Saturday does not appear in the Bible numbers are used such as:  the first day of the week, or the seventh day of the week.  But the phrase “first day of the week” is found in the New Testament (John 20:19).  It occurred in exactly eight places.  Now the phrase “seventh day” occurred 47 times in the Old Testament and 2 times in the New Testament (Hebrews 4:4).  Now if Jesus, Paul or one of the disciples changed the day we should find it some where in the Bible.
