I haven't answered about the elder reaffirmation question in the doctrinal statement, however, I am happy to do so. 

I'm sure you would agree that the New Testament gives us all the information we need for how to conduct ourselves as members of the Lord's church. That being the case, we should expect to find in Scripture where it says how to deal with ineffective and/or disqualified elders. Not surprisingly, such instructions are found in the same book that tells the qualification of elders (1 Tim. 5:19, 20). 

I find nowhere in Scripture that would indicate that elders should be reevaluated by popular vote of the congregation. If there are two or three witnesses as to why a particular elder is ineffective or disqualified let them make their case and let the other elders and/or men, with the evangelist, determine if the charge is valid or not. The very next verse (1 Tim. 5:21) warns of partiality in applying the doctrine. To remove an innocent and godly elder from his office simply due to partiality, including the whims of jelly-backed brethren, would be a very frightening thing to face at the judgment seat! 

I listened to a recording of the proposal of a popular teacher in the brotherhood to institute an elder reevaluation program and I kept thinking that surely someone in the meeting would point out that the Bible tells us how to deal with this issue  - and popular vote isn't it! Sadly, no one did. After hearing, and reading, his arguments for the validity of such a plan I still find no Scriptural authority for having the congregation to vote on whether or not an elder should be removed. Such a plan strips any authority away from those who must be able to rule in the congregations for the spiritual protection of their flocks (Heb. 13:17). With the elder reevaluation plan, if the elders take a stand on an issue that the majority of the congregation doesn't like, well, they can just vote them out and vote others in that will do what they want. Surely, this is not what Christ intended for the front line defenders of the faith! (cf. Titus 1:9-11).
