I have a fair number of friends from the Chicago area. From discussing their church experiences, "leadership" means something a lot different in Chicago than it means in the other parts of America where I have lived and attended church. What they describe is something closer to a family political appointment than a position of service to the greater body of believers. If this is what you are struggling against, you have my deepest sympathy. I would, at best, caution you to guard your heart because you are charting some very dangerous waters that can do a great deal of harm to your walk with God. Bitterness roots easily, grows quickly and is not easy to extract.
First make sure that you have done what you should.
Matthew 18:15-17 15 “If your brother or sister sins, go and point out their fault, just between the two of you. If they listen to you, you have won them over. 16 But if they will not listen, take one or two others along, so that ‘every matter may be established by the testimony of two or three witnesses.’17 If they still refuse to listen, tell it to the church; and if they refuse to listen even to the church, treat them as you would a pagan or a tax collector.
Luke 17:1-4 1 Jesus said to his disciples: “Things that cause people to stumble are bound to come, but woe to anyone through whom they come. 2 It would be better for them to be thrown into the sea with a millstone tied around their neck than to cause one of these little ones to stumble. 3 So watch yourselves.
“If your brother or sister sins against you, rebuke them; and if they repent, forgive them. 4 Even if they sin against you seven times in a day and seven times come back to you saying ‘I repent,’ you must forgive them.”
From these, I see that there is a time and place to confront. There is a call to repent. There is a requirement to forgive.
You claim to have been confronted.
Have you repented?
Have you asked forgiveness? (Were you sincere?)
Have they forgiven you?
[I can answer none of these questions for you, I am not there. I can not look into your eye or their eye. I cannot know the details. Only God can see everyone's heart. ... and the answer is none of my business.]
However, if you have not done what God requires of you, then they are correct to question your sincerity.
If you have done what God requires and they are unforgiving, then you must question the condition of their heart and trust God to deal with them.
What you (actually all Christians) require is fellowship and community. A place to find and give support and practice all of the 'one another' things commanded in scripture.
The only advice that I would offer is that church administration may hand out titles, but no one can stop you from sharing the compassion and support of God with someone in need.
Every Christian is called to be a friend.
Find some place where you can be a friend, and friendship will be returned.
God Bless you and Keep you.
