"You cannot find in God's law any duty to remember, or keep,
the day of Adam's fall, 
or the day of the flood,
or the day of the Savior's birth,
or the day of His death,
or the day of His resurrection,
or the day of His ascension.
--You may remember all these days, but the fourth commandment does not tell you to, neither did the Lord bless and hallow any of these days.
--But it requires the observance of the day on which the Lord rested, which he also sanctified, which was the seventh day of the week; for. He made the world in the first six days of the first week of time, and then rested."
