What They Said

"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."

"There is difference betwixt error, schism, and heresy.  Error is when one holds a strong opinion alone; schism when many consent in their opinion; heresy runs further, and contends to root out the truth.  Error offends, but separates not; schism offends and separates; heresy offends, separates, and rageth.....
Error is weak, schism strong, heresy obstinate.  Error goes out, and often comes in again; schism comes not in, but makes a new church; heresy makes not a new church, but no church......Error is reproved and pitied, schism is reproved and punished, heresy is reproved and excommunicated.  Schism is in the same faith, heresy makes another faith.  Though they be thus distinguished, yet without God's preventing grace, one will run into another."
