Many of our ministry and people hold to the exceedingly curious notion that if error is let alone it will die of itself; and the best way to overthrow this system of error is to disregard it and its methods of interpretation and preach the truth. Error has been a long time in dying under this process. When it has been let alone, it has invariably triumphed. So that this policy has proven a failure; and it is high time a more successful one was adopted in its stead. And the additional advice to preach the truth will, if fully conformed to, set aside the policy of letting error alone. Error, to be effectually met, must be designated. There are many people who can not see, or will not see, the incompatibility of two propositions until they are placed side by side; and any fencing against designating the error, will simply, in these cases, make the truth ineffectual.
