This entry combines structured lexical data with WordToolSet review checks. Definitions, examples, synonyms, and usage notes may come from different source tables, so the page is designed to show evidence from more than one angle before you rely on "heresy" in a final draft.
If a word has several senses, prefer the sense that matches your sentence's grammar and surrounding context. A correct definition can still be the wrong choice when the sentence needs a different register, emphasis, or level of specificity.
Read the first definition as a starting point, then check the example, synonyms, and part of speech before treating "heresy" as the right word for your sentence.
If your draft is formal, technical, persuasive, or sensitive, compare "heresy" with a nearby alternative so the final choice matches both meaning and reader expectation.
Check whether "heresy" is acting as noun in your sentence. A definition is only useful when the grammar matches the way the word is being used.
Compare it with "heterodoxy" and other nearby choices to see whether the sentence needs a softer, stronger, or more familiar word.
Use the example sentence below as an evidence check, then read your own sentence out loud to catch tone or rhythm problems.
Review note: Definition pages are checked for source coverage, sentence evidence, synonym support, and editorial insight before they are treated as approval-ready pages. If the evidence is too thin, the page remains available to users but is kept out of the approval-facing indexed inventory.
Before publishing a sentence with "heresy", ask whether the word helps the reader understand the idea faster. A precise word should reduce confusion, not simply make the sentence look more polished.
When the definition, synonym evidence, and example context point in the same direction, the word is usually a safer choice. When they conflict, revise the sentence or choose a clearer alternative.
"Heresy meant deliberate departure from the accepted doctrines of the church. It was intellectual and spiritual dissent and concerned the beliefs of Christianity, not the morals of its adherents."
"I'm going to declare a heresy for you. All science, if you go back into its roots, saying: 'Why do I believe this?' 'Well, I believe this because of these tests and this proof.' 'Well, why do I believe this?' 'Why did I set up this test?' 'Why did I believe that proof?' All science goes back to something that we believe because we believe it. We believe it because we believe it, and we have no proof for it. It's like a religion."
