Do you "vet" someone before letting them represent your church?

I almost NEVER post anything, only lurk, because of the flaming that goes on, but I'd really like to hear your answers to this one and I'll explain why. I'll try to keep it as short as possible.

Unfortunately, we are landlords. The last tenants said they wanted to buy the house and after a horrible payment history with us, were going to prove they could make payments on time, every time so they would be deemed worthy of a mortgage. We had turned them down, but they begged us to give them a chance and we let them into the house. They declared they are Christians and attend a mega church and that we should come and "hear the music". They enjoy the rock concert before the preacher speaks.

After 15 months, we caught them sneaking out. To make a long story short, they have trashed the house. Filthy, debris everywhere and damage all over. We quit adding up expenses after we reached $6,000.

Our pastor and another pastor we know both said, "speak to their pastor". We did. Put the phone on speaker phone so we both were included in the conversation and emailed photos while on the phone because their pastor ask for the pictures. At the same time this happened to us, the tenants showed up in the local paper under the legal notices. Two different loan companies were suing them for breach of contract. We all know what that means.

None of this phased the pastor. Instead he put them a couple positions of leadership in the church since then. Hmmm. We find this sad.

Another local Baptist Church now has a known anti-Semite writing their church news. He is actively promoting his beliefs on his face book, so we know he hasn't given up his anti-Semite beliefs.

Just yesterday, a man we used to go to church with visited with us and told us about a family member that he had prayed for finally started going to church with him, but because someone in leadership in the church was found guilty of a crime which was known and ongoing when he was picked for leadership, has stopped going because he doesn't understand why the church would allow someone like that to be in a position of leadership to being with.

Who represents your church at the door and in positions of leadership can have a very profound affect on those attending. What a stumbling block.

Please don't start in with "nobody is perfect". We know that. I've also left out a lot to make this as brief as possible, but the question is still the same. Do you let just anyone who asks serve as representatives or as leaders, or do you do some investigating first?

I'll crawl back into my cave now.
