The CORNERSTONE  DOCTRINE of the SDA Church is the SANCTUARY DOCTRINE:

[From the SYMBOLISM of the Earthly Sanctuary to the REALITY of the Heavenly Sanctuary]

And he said unto me,

Unto two thousand and three hundred days; (years)

then shall the sanctuary be cleansed....

*We have such an high priest,
who is set on the right hand of the throne of the Majesty in the heavens;
*A minister of the sanctuary, and of the true tabernacle,
which the Lord pitched, and not man.
1) Then verily the first covenant had also ordinances of divine service, and a worldly sanctuary.
--For there was a tabernacle made; the first, wherein was the candlestick, and the table, and the shewbread; which is called the sanctuary.
--And after the second veil, the tabernacle which is called the Holiest of all; Which had the golden censer, and the ark of the covenant overlaid round about with gold,..
--Now when these things were thus ordained, the priests went always into the first tabernacle, accomplishing the service of God.
--But into the second went the high priest alone once every year, not without blood, which he offered for himself, and for the errors of the people:
2) But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, Neither by the blood of goats and calves, but by His own blood He entered in once into the holy place, having obtained eternal redemption for us.
--For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh:
--much more shall the blood of Christ, who through the eternal Spirit offered Himself without spot to God, purge your conscience from dead works to serve the living God?... but now once in the end of the world hath He appeared to put away sin by the sacrifice of Himself.

-**-And as it is appointed unto men once to die,

but after this the judgment.....
