WHICH TRUTHS ARE CATHOLIC TRUTHS?

WHAT IS A HERESY?

Chapter 6

Student I have sought to know some things about catholic truths. But now let us pass on to the heresies opposed to them. First of all, however, I want to know if you have found a definition of heresy given by anyone.

Master Some people do define or describe heresy, saying that a heresy is a false doctrine contrary to orthodox faith. "False doctrine" is put in this definition in place of a genus because every heresy is a false doctrine, but not every false doctrine should be regarded as a heresy. For, as we find in 24, q. 3, c. Inter heresim [col.997], Jerome clearly attests that every heresy is a false doctrine, saying, "A heresy involves a wrong doctrine." A wrong doctrine, however, is a false doctrine; therefore a heresy is a false doctrine. But not every false doctrine is a heresy. For according to Augustine in the Enchiridion [bk.2, ch.63], it is no sin or a very small one to err in many things; but like infidelity a heresy is the heaviest sin. Therefore not every error is a heresy. We conclude from this that not every false doctrine is a heresy, since every error should be considered a false doctrine. According to them, therefore, "false doctrine" is not unsuitably put in the description of heresy in place of a genus; "contrary to orthodox faith" is put as a difference; for through this a heresy is suitably distinguished from other falsities which are not heresies, since other false doctrines are not contrary to orthodox faith, and therefore are not called heresies.
