I am appalled that, for whatever reason, the vicar does not at least challenge the bullying behaviour . I can understand them wanting to include everyone, not cast anyone out etc, but bullying under any circumstances is totally unacceptable and there is never a reason to justify it - whatever the background, personal circumstances, familial or social relationships, environment, financial contributions etc it will always be wrong. I have no faith myself but would give 100% support that people like yourself that do have that belief should have a safe place to go, and your church should be a safe place not a place of torment and dread....your vicar needs to be made aware (or more aware if choosing to ignore) as your God would want you to feel safe and content in one of his many homes. If the vicar refuses to speak to the bully, explore their reasons then tell them how it is not OK to continually upset other members then go over his head to somebody higher up in the church hierarchy - go to the very top if you have to and garner as much support as you can from other members...a letter signed by the majority of a congregation may carry more weight. Some churches have suffered a big decline in numbers of people attending, some have been forced to close...it would be a shame if your beloved church found itself threatened by a massive reduction in numbers and closure if people were prepared to say how unhappy membership has become, how they go for friendship and faith and do not expect to be threatened or yelled at. Even if this bully is financially contributing a lot to the church this should not influence the vicar in not challenging the bullying...you should not be able to buy your way to the seat next to God and all that - I thought all gods loved rich and poor alike and if someone donates to a cause it should not buy them any preferential treatment...I wouldn't expect to dictate to a vet how to treat an animal just because I donate to the PDSA!
I really hope you can find a way to resolve this and once again be happy and content at your church. You should look forward to attending services, events, groups not dread them, be fearful of verbal assaults or being physically threatened, you should feel safe and loved there not intimidated.
Some churches did nothing about clergy offending against children or the vulnerable. Point out to the church that this is also a subject they cannot ignore, bullying, threatening, putting others down, making people feel bad, trying to control everything and always wanting your own way is not very religious, not charitable and not acceptable.
