Mt 4:19 Then He said to them, "Follow Me, and I will make you fishers of men."
A common belief among Christians is that it is possible for a person or organization to "destroy" you. I have seen (and sometimes experienced) expulsions, firings, divorces, smear campaigns, etc., that happened to Godly people. In some cases, they were innocent, sometimes they were guilty, and often the truth lay somewhere in between.
In Jesus' promise, two Greek words are used for "follow." One is "Come," and it is a strong form of the word. The other Greek word is "after" or "behind." What Jesus literally said was "Come behind Me, and I will make you fishers of men."
Sometimes, a small group of rebels will seize power in a church. Jesus will have nothing to do with their sin, and if you follow after Him, you won't participate either. Sometimes you might feel that you should seize power for the greater good, but if you follow after Jesus, Who never rebelled against the authority of Rome, you won't do it.
One of the "dark secrets" of Christianity is that many Godly churches were started by people who had been cast out of other churches, or who had left other churches because of sin in the leadership. What you, personally, need to do is follow after Jesus, regardless of the consequences.
Were you run off from a church by people who were not fishers of men? Good for you. Now, study His Word diligently, so you'll know what He wants you to do, and then do it.
