The Philosophies of Men
These philosophies as a source of information is based on the opinion or theory of an individual or a group of people. It is transitory, unreliable and should be seen as suspect when weighing a source of the information until it has been proven to be accurate.
The opinions and philosophies of men have been present in the world imaginably since it began. In politics, philosophy and religion people have raised their opinions and conclusions as if they were facts of science or truth. They don't speak with any authority that God has given them.
These professors of knowledge assume or presume that they can dictate an opinion about scripture, start a church, start a political faction teaching their position on the matter.
The good will and love of a pastor or minister can have a great effect on a person. Politicians likewise can fabricate a mesage of hope or prosperity. If it were not so they would not gain any following. This they can do of their own accord and act without actual authority from God. In the success of their endeavor they may mistaken such success as approval from God when no such evidence of authority has been granted.
