"We find not only that the sanctuary in heaven is the grand center of
the Christian system, as the earthly was of the typical, but that this subject is the center and citadel of present truth.
--And since our temple is in heaven, and in that temple, 'the ark of His testament,' containing 'the commandments of God,' and in the very midst of these commandments, the Sabbath of the Lord, fenced around by nine moral precepts that cannot be overthrown,
--it is no wonder that the enemies of the Sabbath should not only strive to abolish the ten commandments
--but to demolish the true sanctuary in which they are deposited beneath the mercy seat—the throne of God."
R.F.C. 1863
Remember the sabbath day, to keep it holy.
Six days shalt thou labor, and do all thy work:
But the seventh day is the sabbath of the LORD thy God:
in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates:
For in six days the LORD made heaven and earth, the sea, and all that in them is, and rested the seventh day:
wherefore the LORD blessed the sabbath day,
and hallowed it.
Exodus 20:8-11
