HI KistByQpid
I do not think JW describe themselves as christians as much as other churches do. They like to emphasis that they are a 'Jehovah's Witness' rather then a christian...mainly because the name Jehovah identifies them as different to other 'christians'.
I rarely came across a witness who referred to themselves as christians...rather they were witnesses...to be a christian you could be anything...and they do not want to be referred to as another nutto in christendom...lol.
In saying this however...I have no WT reference to suggest that they were discouraged from using the term 'christian' when referring to themselves...it was just an observation I made.
