I have looked at several of the biblical passages that might appear to apply to this situation:

Quote
But avoid foolish controversies, genealogies, dissensions, and quarrels about the law, for they are unprofitable and worthless. As for a person who stirs up division, after warning him once and then twice, have nothing more to do with him, knowing that such a person is warped and sinful; he is self-condemned.

Titus 3:9-11


Quote
I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them. 18 For such persons do not serve our Lord Christ, but their own appetites, and by smooth talk and flattery they deceive the hearts of the naive.

Romans 16:17-18

Quote
If your brother sins against you, go and tell him his fault, between you and him alone. If he listens to you, you have gained your brother. But if he does not listen, take one or two others along with you, that every charge may be established by the evidence of two or three witnesses. If he refuses to listen to them, tell it to the church. And if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.

Matthew 18:15-16

My question has to do with application. The passages in Titus and Romans are referring to obstinate heretics, not individuals who may inadvertently cause divisions by standing up for the truth. This lady believes that false teachings have infiltrated her church that threaten to undermine the gospel -- I do not find her claims or the evidence she offers compelling -- but she sincerely believes them. At this stage she is not openly trying to cause division. The main thing I find troubling is the fact that she joined this church believing that it was deeply corrupted, with the intention of reforming or redeeming it. That is what I would first like to address. An analogy might be a Reformed Christian who joined an Arminian church with the intention of reforming it. This just doesn't seem biblical, but I'm having difficulty formulating a thoroughly biblical objection and would appreciate some suggestions or guidance.
