And he shall speak great words against the most High, and shall wear out the saints of the most High, and think to change times and laws: Daniel 7:25
"The Pagans derived their Sunday-keeping from the Devil.
When men apostatized from God, the Devil turned them to the worship of the Sun.
And instead of the holy Sabbath
which the Creator had instituted as the memorial of Himself,
Satan set apart the first day in honor of the Sun.
As the Sabbath of the Lord can be traced back to Him by whom it was instituted,
so this first-day festival,
the rival of God's Sabbath,
can be traced back to its author, the Devil."
