Elaine,

Sabbath is a Jewish thing.  You are right about that.  So if I follow your argument it would be okay for Jews to press for their right to observe the Seventh-day Sabbath, but it is not ok for Adventists because the Seventh-day was not given to Christians.

A summary of the Keynan Constitution available online says: 'According to the [Kenyan] Constitution, a person has the right to refuse any act contrary to their religion or belief, including the taking of an oath.'
