Sad to say, but some individuals or churches seem to have a lot more requirements for people in ministry--and sometimes even for retaining one's membership in their congregations.
First Timothy 3:2-6 and Titus 1:6-9 set some very high standards for those seeking ministry positions, but I've known churches that seem to believe like the Pharisees that they must set even more qualifications for ministers--so high that even Jesus couldn't humanly comply with some of them:
1) Must be a husband. Jesus wasn't married when He lived here on earth.
2) Must have obedient children. Jesus didn't have any physical children
3) Must disassociate with sinful people. That pretty well disqualified Jesus throughout most of His earthly ministry.
4) Must only associate with "acceptable" people. Like the Pharisees Jesus condemned--and were the ones who eventually got Him crucified
5) Must never touch alcoholic beverages. Like the water He turned into wine or what He usually drank along with most of His meals.
6) Must stay away from women who've had questionable morals. Like the Samaritan women at the well or Mary Magdalene.
Those are just six things some people have imposed on those seeking ministry positions. If Jesus Himself couldn't pass muster with them, how they expect mortal men to do so is beyond me.
Then you also have some folks who insist that someone in a ministerial position must have never been married then subsequently been divorced--regardless of the circumstances surrounding that divorce.
IOW, if his first wife deserted him and had intimate relations with another man and subsequently sues for a divorce, the minister is guilty even if he had no fault on his behalf. He's divorced, thus he must go & no other church should be able to use this man in any of their ministerial positions either.
Even if a person in a ministerial position has committed a sin against the Bible's qualifications, if he truly repents & seeks forgiveness from that church, some churches STILL will not let that person serve in any ministerial position.
God Himself may have forgiven him, but not that church. Jesus forgave the woman caught in adultery in John 8:3-11, but there are some churches who'd cast stones at a person who may have stumbled but then truly repented and sought for forgiveness.
Point is that some people or churches put so many extra-Biblical & unreasonable requirements for people in ministerial positions that eventually they wind up losing many God-called ministers or getting few if any persons seeking to serve Him at their church.
Then they look at each other and wonder why their church isn't prospering and getting ministers--or even members not in any particular ministerial position--to replace those that they've summarily dismissed.
I guess they're waiting to see some handwriting on their empty platforms like Belshazzar did in Daniel 5. The king saw the handwriting indeed, but then it was too late. In no time at all, he was killed & his once powerful empire was destroyed.
Unfortunately, some churches who may have started out with good spiritual success but now are so smugly indifferent about their leaders (or even some members who've failed to meet their "qualifications") who are about to be canned, may wind up with the same fate as Belshazzar & his one-powerful empire did.
