Sectarianism is the withdrawal from and letting go of culture. "Visiting sectarian churches is like visiting a museum dedicated to the past. This is because all sectarian churches eventually become dated from being removed from people in the world. Sectarians do not live by the necessary faith in the gospel and therefore believe that evil hearts and sinful actions and worldly social structures are more powerful than God, unable to be redeemed, and therefore are a waste of our energies because they are destined to be meat on God's grill anyway, so why bother?" (Mark Driscoll | Vintage Church)
