Hmmm....Not sure about that one Woody. I can think of the Adam-God theory, Blood Atonement, Mc Conkie teaching that Black people will never receive the Priesthood (and later on publicly say he was wrong) and so many other "teachings" that were clearly not perfect because if they were, there was not a need to recant them as they have done in some of these teachings you know what am I saying? Yes, lots of philosophies of men mingled with scripture. Lots of opinions but not necessarily doctrine.
I think it's safe to say that in every religion, men teach philosophies of men mingled with the scripture. Some seem to do it quite often while others seem to have literal interpretations of the scripture. The LDS Church is not exempt from this. We hear a lot of philosophies of men. The important thing is to recognize the difference.
This has been the problem of many religions but I find it particularly prevalent in Mormonism since the interpretation of its own doctrine changes with the 'season'. Even their prophets contradict each other.
Its knowing when the Lord is actually speaking and when its an interpretation of the writer or even the reader.
A pause from Philosophies Of Men, Mingled With Scripture to share correct from antiquity:
