If there is no local reformed church you can be a part of in good conscience, then I would take this as a sign that you should move to a place where you can. I am not saying that you should leave immediately...go through whatever channels you can to protest to member in question, and then to the church with the established procedures in place. If that is unfruitful you still don't *have to* leave as there may be a place for you to call the church to repentance, even repeatedly. It depends on the situation.
