Gothard has always been controversial among biblical Christians. Many of his teachings are Old Testament-based and/or teachings he made up himself. There are rules for everything - what to eat, how to treat illnesses (really goofy), what to wear, how to apply makeup, why people shouldn't adopt children, etc. Children should not attend colleges and must wait until they are married to move away from home, etc. But on top of this, he's never married or had children of his own, and he's long been known to engage in inappropriate activities with young ladies who come to work at his Institute. He's finally being investigated, and he resigned from IBLP in March. Many of his "disciples" are still in denial about him, but eyes are slowly being opened.
