The Message of the Other Angel

Thus the substance of the second angel's message is
again given to the world by that other angel who lightens
the earth with his glory. These messages all blend in one, to
come before the people in the closing days of this earth's
history. All the world will be tested, and all that have been
in the darkness of error in regard to the Sabbath of the
fourth commandment will understand the last message of
mercy that is to be given to men.

(Remember the New Moon day, to keep it Holy, Six day shalt thou labor ...)
Genesis 1:14 And Elohim said, Let the lights in the firmament of the heavens separate the day from the night; and they will be for signs, and for seasons, and for days, and years:

Revelation 14:7 Saying with a loud voice, Fear Elohim, and give glory to Him; for the hour of His judgment is come: and worship Him that made heaven, and earth, and the sea, and the fountains of waters.

Worship Him as Creator, and respect the lights of the heavens as His established calendar, for all moedim, appointments.
Forsake the Roman calendar with its continuous freewheeling weeks, colliding with the lunar month festivals.

On the tablets of stone, as Yehoshua lifts the cover of the Ark of The Covenant:

Early Writings page 255 "They trace down the lively oracles, but start back with trembling when they see the fourth commandment among the ten holy precepts, with a brighter light shining upon it than upon the other nine, and a halo of glory all around it" ... "Six days shalt thou labor, and do all thy work: but the seventh day is the Sabbath of Yahovah thy Elohim"
