"…Brothers are appointed by Holy Spirit."
But keep in mind that Holy Spirit only considers those that the Body of Elders recommends as Ministerial Servants and Elders, then only if the Circuit Overseer agrees with the Body (He usually wants them to be unanimous).
Nothing new here, but most Bodies will refrain from appointing a brother if one elder can apply any scriptural reason to say that he isn't comfortable with a recommendation. You can apply one scriptural reason to ANYBODY. So, if Johnny was dating his daughter but she broke it off, Elder Bob can say he is not "serious." Any elder can accuse a brother of some unknown secret then say he is not "free from accusation." A married man, they look at his wife and kids and say that he is not "presiding in a fine manner" over his household. If they are really pressed, you can get somebody to say they occasionally miss a meeting or weekend of field service, then they don't have a "fine standing." (1 Tim. 3:8-13)
Truly, it's those who get their noses stuck far up the obedience line who are appointed. Nothing new again, but as one who was an elder for many years, I am not proud to say that I was very obedient until I learned to think for myself. Some of the best brother had a very independent attitude about them and never got appointed.
