Neo-Pharisees reject faith living because they love law. Instead of receiving the free gift of grace, they feel compelled to go to religious law school and after graduation they feel they can negotiate a legal relationship between themselves and God and also everyone else and God. Like a flashback to
Acts 15, they encircle legalistic laws and yokes in the mandatory for salvation classification and harshly lay them upon the people of God.
They are proud and presume themselves to be experts in interpreting Biblical scriptures that are obscure and difficult to understand.
They can pull isolated scriptures from the Old Testament and even though they cannot find precept upon precept and line upon line to support their interpretations they insist that everyone should accept their superior decoding of all these scriptures.
With this kind of flawed exegesis they erect major doctrines that serve as criterion for fellowship. They seem to feel solely qualified to cross every t and dot every i for every pastor, teacher and saint, even on scriptures that are relative and broad in principle only.
