Bro. Eli taught that the real Sabbath in the Bible is not the old seventh day as instructed by Joshua and Moses.
Apostle Paul explained to the Hebrews in Hebrew 4:8 that God was speaking of a different day.
This tells us that the Initial Keepers of the Sabbath day were not following the same day Paul mentioned
It is seen in John 5:16-18 that the jew wanted to kill Jesus because He worked on the Sabbath day, therefore Jesus did not practice the old Sabbath.
Bro. Eli furthermore explained from Hebrews 7:12 that the law was also modified when the priesthood shifted from Moses to Christ.
Christians must follow commandments of Christ now because the old Sabbath had ended
True rest not found in the old Sabbath of the law of Moses but it is found in Jesus.
