One point in legalism is the Leaders of a Church imposing their own standards of conduct,that is apart from God's Word.
When a member violates the self imposed standards of the leadership,they are condemned by a dichotomy of twisted theology that is extracted somewhere in the Bible.
In a Church where a gospel of convict and challenge is taught every service,one of 2 things will happen.
1 The Church membership will drop or stay small,due to the illogical unbiblical concepts that aretaught.
2 The Church becomes a enigma to everybody except a small group of zealots, and becomes a cult.
Legalism is demonic,it spews lies and accusations against Christianity.
Some examples: Jim Jones.
Westboro Baptist.
These are extreme but on a lesser level untold thousands of people are run out of Church by legalism.
I believe that legalism is a by product of Narrissism.
The Leader or Pastor has his favorites all scrambling around trying to earn favor, as well He has his scapegoats he enjoys embarrassing before the Church.
As well the leader will enjoy a do as I say not as I do reign of UN Godly acts.
They are relentless in their pursuits of torture all the while stating how very much they embody God's love.
They even cast spells:
Statements such as if you miss Church just because of your new boat God may just sink it.
Or I won't pray for his cancer cause God is taking him to the wood shed.
Legalism is demonic.
