And God blessed the seventh day, and sanctified it: because that in it he had rested from all his work which God created and made. Genesis 2:3Q: Since God Sanctified the 7th Day...WHY do many keep another day "Holy"?
And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.
John 10:16
There are others who are keeping false doctrines....but Christ will call them out by His Voice (His Word-the Bible which He speaks to us through).
---HEAR THE VOICE---
Remember the sabbath day, to keep it holy...But the seventh day is the sabbath of the LORD thy God: in it thou shalt not do any work......If ye love me, keep my commandments.
Exodus 20:9,10/John 14:15
