Brother Intellectual - Perhaps because he went to college before he was a witness, this brother actually has a brain. He is therefore considered by others--and often considers himself--to be an authoritative expert on theology, science, and basically any and every academic discipline. He bestrides the congregation like a colossus; his word is unquestioned. He reads all the WTS publications, and probably has some private doubts, but spouts off elabortate justifications and defenses if anyone else expresses those doubts.
There is an elder just as you described in my last congregation. Everyone thinks this guy is so great and smart. He really is a great speaker it is no wonder he makes really good money in sales.
He always encourages people through his nicely worded talks to reach out to those less fortunate, associate with everyone in the congregation, it is ok if you are single and cannot find a mate, it is ok if you work at Mc Donald’s for peanuts.
But you would never find this elder associating with weak ones or people in a lower financial class than he. And he always seems to be driving the most expensive car in the parking lot.
Sometimes I think elders like this are only in the org. for fame and glory.
