John D. Roth said this quote

Throughout history, Christians have faced the persistent temptation of confusing the language we use to talk about God with the essence of Christian faith. This stubborn human tendency to turn doctrine into an idol - to confuse a human creation with the truth itself - can easily lead people to wield doctrinal claims as a weapon against minority or dissenting perspectives. Thus, anyone who does not line up with a certain formulation of Christian faith is not only wrong, but also a heretic and therefore worthy of punishment or death.
