The church is made up of people. And people, by their very nature, are imperfect. Sadly, I think too many people are treated poorly by someone associated with the church and remember that pain and wrongdoing as an action by the church as a whole instead of the action of a single individual.
It may sound like semantics, "hurt by the church" or "hurt by someone in the church," but such a viewpoint can poison one's outlook towards the institutionalized church and organized religion. It can negate the benefits of being part of a church body. It also raises your risk of putting God by the wayside because of a mistake a person made. Don't do it.
