Just an idle observation on an unconstitutional constitutional provision

Hard to imagine this being challenged ever, since someone who did would be run out of the state on a rail.  But it plainly runs afoul of the U.S. Constitution:

CONSTITUTION OF THE STATE OF MISSISSIPPI
Article 14. GENERAL PROVISIONS
Current through 2011 

§ 265. Denial of Supreme Being disqualification to hold office 

No person who denies the existence of a Supreme Being shall hold any office in this state.

1817 art VI § 6; 1832 art VII § 5; 1869 art XII § 3.

Goes to show that you never know what you'll find when you go thumbing through the 1890 Constitution.
