The success of an illegitimate coiner depends largely upon how closely the counterfeit resembles the genuine article. Heresy is not so much the total denial of the truth as a perversion of it. That is why half a lie is always more dangerous than a complete repudiation. Hence when the Father of Lies enters the pulpit it is not his custom to flatly deny the fundamental truths of Christianity, rather does he tacitly acknowledge them, and then proceed to give an erroneous interpretation and a false application.
