Section 346. Changing number of laymen trustees

An incorporated church to
  which this article is applicable may, at its  annual  corporate  meeting
  where  trustees  are  elected,  by a majority vote of the duly qualified
  voters at such meeting, change the number of its trustees by adding more
  trustees, one-third of which shall be elected for three years, one-third
  for two years and one-third for one year; or by  voting  to  discontinue
  the  offices  of certain specified trustees as they expire, one-third of
  said offices to be discontinued each year, until the number left is  the
  number  decided  upon.  No  such  changes  shall affect the terms of the
  trustees then in office, but each shall hold office until his full  term
  has  expired unless his office shall terminate as provided for elsewhere
  in this article.
