What amazes me is that for many years I believed this to be an unwritten rule when in actual fact it is a written rule. I managed to read the branch correspondence guidelines that basically instruct elders to not give privelages to any brother wearing a beard after having been admonished.
Reference??
In the 2007 version of the Correspondence Guidelines, I can find only one reference to beards, and that reference just references publicly available Watchtower and Awake magazines
Page 20: CLOTHING AND GROOMING
When replying to specific inquiries on clothing and grooming, the following references in our publications may be helpful.
The wearing of a beard: g79 4/22 27-8; w75 8/15 500-501; w73 3/1 137-40.
Brothers wearing beards do have, and continue to have, congregational 'privileges' - not all congregations are the same.
