Christians the week's first day for Sabbath hold;
The Jews the seventh, as they did of old;
The Turks the sixth, as we have oft been told.
How can these three, in the same place and day,
Have each his own true Sabbath? tell, I pray.
(In reply to
re(2): faint idea by Mindrod)
In fact, if the same place is the deck of a ship, and the same "day" means in the same 24 consecutive hour period, then crossing the date line could change the day of the week without changing the "day" on which their Sabbaths are observed.
