Have you ever noticed that the word heresy, is a form of the word heresay?

Question

In other words, "parroting". Or repeating what one hears. Not even knowing if it's the Truth!

Answer 1

It's not.

"hearsay" is a blend of hear and say, namely an idiomatic expression.

Heresy is a separate word:

The word "heresy" comes from the Greek αἵρεσις, hairesis (from αἱρέομαι, haireomai, "choose"), which means either a choice of beliefs or a faction of believers. It was given wide currency by Irenaeus in his tract Contra Haereses (Against Heresies) to describe and discredit his opponents in the early Christian Church.

Answer 2

The word "heresy" comes from the Greek αἵρεσις, hairesis (from αἱρέομαι, haireomai, "choose"), which means either a choice of beliefs or a faction of believers. It was given wide currency by Irenaeus in his tract Contra Haereses (Against Heresies) to describe and discredit his opponents in the early Christian Church. He described his own position as orthodox (from ortho- "right" + doxa "thinking") and his position eventually evolved into the position of the early Christian Church.
(from wikipedia)

as you can see, heresy, far from any implications of parroting, means having a mind and not being afraid to use it to disagree with the accepted version of events.

if you care to read further on the wikipedia article, it also states:
"For a heresy to exist there must be an authoritative system of dogma designated as orthodox".

Dogma is defined as:
Dogma (the plural is either dogmata or dogmas, Greek δόγμα, plural δόγματα) is the established belief or doctrine held by a religion, ideology or any kind of organization, thought to be authoritative and not to be disputed or doubted.

So you see, heresy, by definition, is to question, to NOT repeat what one hears. It seems to be the orthodox (non-heretics) who do all the parroting.

Answer 3

Actually it comes from the Greek word hairesis meaning to chose a faction. The variation heresy means to chose a faction outside of the accepted belief.

Answer 4

"Heresy" is from the Latin heresie, which means "school of thought" or "philosophical sect." It was used by early Christians to describe anyone who had unorthodox doctrines.

"Hearsay" is from the 1500s expression "to hear say" relating to listening to evidence in court. It may be related to the old English adjective "hiersum" which means "obedient."

They don't have the same roots, nor similar meanings. Sorry.

Answer 5

No, sorry, look up the etymology and you will find it is even weirder than that.
