Nuns wearing wedding bands? On a recent trip a nice nun took a picture of my family.  I noticed that the nun was wearing a wedding band on her left hand.  I have a vague recollection of reading somewhere that nuns are considered to be “brides of Christ”, which leads to my two-part  question.

Do all nuns wear these symbolic wedding bands?  If not, is this practice limited to certain religious orders, or is it an individual choice?
Roman Catholic nuns consider themselves a "Bride of Christ," and as such some wear a wedding ring.  This of course assumes that the nun you saw was a Roman Catholic nun.  Some nuns (or similar laity, such as Lutheran deaconesses) in other faiths are not bound by the same celibacy vows or simply do not wear wedding rings.
