Mrs. Robinson, if you don't mind my saying so, this conversation is getting a little strange.
You may or may not be aware of the recent revelations of sexual harassment/abuse perpetrated by Bill Gothard, head of the Institute in Basic Life Principles.* In response to such, Bill Gothard has resigned from the presidency of IBLP.
To be fair, accusations of impropriety and divergence from Scripture is nothing new, as can be seen in the 2002 book, A Matter of Basic Principles: Bill Gothard & the Christian Life.
A recurring question I've seen is, "How could this have happened?!"
The answer seems obvious to me. The organization is a cult.
As is typical with a cult, it has a charismatic leader with a loyal following that is rather unhealthy. The IBLP is awash with legalistic practices, as opposed to Scriptural dictates, and there's no accountability for said leader. For many, sadly, the organization replaces the role of the local church in the life of the participants and/or the people are more loyal to the organization than they are to a local church.
That's not to say something along these lines couldn't happen in a legitimate church, but it's less likely in a properly structured church, especially one that understands the biblical admonition to put no confidence in the flesh, but to have a healthy self-distrust and reliance upon the Spirit of God to sanctify.
* See how the experiences Ruth, Annette, Charlotte, Rachel, Meg, Lizzie, and Grace had with Bill Gothard fit together chronologically here, and behaviorally here.
