Heresy is any provocative belief or theory that is strongly at variance with established beliefs or customs.
- And so we get an idea of the real fundamental meaning of the words Catholic and heretic. A heretic is one who has his own opinion. What does having an opinion mean? It means following one's own ideas, one's own particular notions. Whereas the Catholic, on the other hand, is what the name signifies, that is to say one who, not relying on his own private judgement, puts his trust in the Church, and defers to her teaching.
- In the Code of Canon Law the term heretic means a baptized person who, while retaining the name of Christian, stubbornly denies or calls in doubt any truth which is to be accepted on Divine and Catholic Faith. ...a similar excommunication is incurred by those who publish books written by heretics upholding and commending heresy, and by all who defend or knowingly and without due permission read or keep these or any other books prohibited by name by letters Apostolic.
- The word "heresy" not only means no longer being wrong; it practically means being clear-headed and courageous.

- Anyone who seeks for the true causes of miracles, and strives to understand natural phenomena as an intelligent being, and not to gaze at them like a fool, is set down and denounced as an impious heretic by those, whom the masses adore as the interpreters of nature and the gods. Such persons know that, with the removal of ignorance, the wonder which forms their only available means for proving and preserving their authority would vanish also.
- In English-speaking countries, the connection between heresy and homosexuality is expressed through the use of a single word to denote both concepts: buggery. ... Webster’s Unabridged Dictionary (Third Edition) defines “buggery” as “heresy, sodomy.”

- Nay, it has come to this, that Truth meets no where with stronger opposition, than from many of those that raise the loudest cry about it, and would be taken for no less than the only dispensers of the favors and oracles of Heaven. If any has the firmness to touch the minutest thing that brings them Gain or Credit, he's presently pursued with the hue and cry of Heresy.
