The real problem with Bible alone, is that it gets in the way of teachings and traditions of men apart from God.
There are people who really, really like lies over truth, especially when they really really study them very very carefully.
Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;
Speaking lies in hypocrisy; having their conscience seared with a hot iron; Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth.
Who would want to forbid men to marry, or to abstain from certain meats?
Those who reject the Bible is the sole source for traditions and doctrine and commandment of God.
Why go through all the psycho-babble of pretended honor toward Scripture, in order to reject Scripture? Just be open and honest about it, and say you don't want to be limited by Scripture, because you really like a bunch of other stuff outside Scripture.
