The issue isn't so much about what you call a clergy, but whether a man has been called to the ministry. In today's world, we see members of the clergy with outer vestments with some (like the Catholics) sporting garish mitres and robes that clearly have pagan origins. Such vestments were foreign to the early church, which tended towards a lay clergy. But over the Internet, anyone who wants to start a church can buy "elegant clergy vestments" and "fine clergy cassocks," get a ministerial certificate (suitable for framing) and they're in business...literally.
The outer vestments were devised around the fourth century and the liturgical colors gained significance in the ninth century. As one scholar notes: "The liturgical colors are first given significance in the ninth century. The Roman clerics say, the devout Catholics say, and the great authorities on this concede that they have absolutely no antique or sacred Christian background. In themselves, the colors are not ancient, and they are not at all sacred in the church." Aaron was given special priesthood garments under Moses and by revelation that he might minister as a priest. But no such vestments were adopted by the first century church. Neither were the haircuts, mandatory beards, etc.
But how do the Witnesses claim the authority to baptize, lay on hands for the gift of the Holy Spirit, administer to the sick and ordain others? How does a person acquire such authority? And can it be gained through the Internet?
The interesting thing about the clergy is that what gives the governing body of Jehovah's Witnesses such authority? If you can't get it through the Internet, where can you get it? Does the governing body have more authority than those who will send you a certificate of ordination?
Who is supposed to administer such rights and privileges? I don't see anything in the Bible giving anyone in the modern day such authority. Yet shouldn't God administer it in some way? But if so, how? Modern clergy is simply a system of priestcraft by which men mutually recognize each other's authority. Within 30 days I can become a duly recognized member of a clergy that's every bit as legitimate as anyone else's. I can post my ministerial certificate, get a special parking permit, a collar of my choosing and some pretty fancy robes for Sunday. I will be able to baptize (sprinkle or dunk), perform marriages, collect contributions (plates available at special rates), ordain others and preach, teach, expound, exhort and did I say collect contributions? I can also cast out demons and get tax cuts.
That, my friends, is the problem with a clergy. I don't need an existing church to sponsor me; I can start a new one. I can teach right from the Bible and interpret scriptures in any way I see fit, and I can say I was guided the entire time by the Holy Spirit. But I don't have to wear vestments. I can start a Bible study and work through my own publishing company. And I can find things in the Bible and interpret them to refer to me. And how will I be any different from the folks at Bethel?
