I want to know the answer to the following question:
What is the study of heresy?
All the background I'm provided with is that "The term heresy is from Greek αἵρεσις originally meant "choice" or "thing chosen", but it came to mean the "party or school of a man's choice" and also referred to that process whereby a young person would examine various philosophies to determine how to live.". Is that enough to answer the question?
