Merriam Webster’s on-line dictionary defines “demean” as “to lower in character, status or reputation”. Your question seeks comments regarding the “demeaning” of paid clergy, by Mormons and JW’s, asking the reasons why this is so. Being an ex-JW, I will focus my response on the JW aspect of your question.
One reason the WT organization demeans paid clergy is ‘part and parcel’ to their elitist claims of being the sole purveyors of “Truth” today. Also, their well published, self-promoted claims to belonging to God’s sole “spirit-directed” organization today also fosters a sense of superiority over all other religions, including its better educated clergy. As such, all members of the clergy are viewed as followers of Satan and part of false religion as exemplified by the great harlot, Babylon the Great (Rev 17:1-8), according to WT teachings.
There is also a general sense, among JW’s, that paid clergy tend to be more gifted with “worldly wisdom”, i.e. the philosophies of men, as opposed to spiritual wisdom from God. This common view also tends to demean the clergy.
In direct contrast with paid clergy, JW’s appointed elders and/or ministerial servants (deacons) have no formal training of any kind. That some were fortunate enough to have attended college is incidental. The most important requirements for appointment to the office of elder are 1) demonstrating strong, unwavering loyalty to the organization (company men, as one mentioned) and 2) diligently and regularly showing support for all the organization’s programs, initiatives etc… and 3) elders being very familiar with all the judicial ‘rules/regulations’ found in the secretive Elder manual, “Shepherding the Flock”. In judicial matters, keeping the congregation “clean” and free of what the Watchtower considers to be “spiritual contaminants” is of the utmost priority.
Therefore, the results of demeaning or minimizing the need for formal secular training, in general, are predictable. WT elders are ill-equipped to provide any level of professional counseling in the areas of marital problems, child sexual/physical abuse, depression, suicidal thoughts etc… The common thread of ‘counseling’ in their visitations is limited to exhortations to “reading the Bible more”, “praying more”, “spending more time in the door-to-door work” etc…. as if these activities, somehow, are bona fide means of treating and/or resolving serious personal/family problems. There is a huge disconnect in this area, causing many to leave the organization, either by “fading” away or direct, formal disassociation.
Until the WT organization gives serious attention to this area, the results of using untrained elders will be "hit or miss", not a formula for success.
Note to "Porcelain Vessel"?:
You are 100% correct, the apostles were uneducated when compared to the Pharisees. But you overlook that these "unlettered" men were speaking directly and forthrightly by means of the holy spirit (Helper) which, as Jesus said, would "bring back to your minds all the things I told you" [John 14:26]. The events of the 1st century cannot be compared, even remotely, to our time. Elders today speak, counsel etc... those in need on the basis of what the WT organization has instructed them to say, in accordance to the Shepherding the Flock manual. Do you really believe the holy spirit operates upon them as it did in the 1st century? I think not....
