Actions, statements, and thoughts which fall outside of that which is in the Holy light of the God-Emperor of Mankind, and, thus, into the unholy darkness of the Ruinous Powers. Inquisitors, through their holy judgement, seek out and destroy heresy wherever they find it, through any means necessary, including the drastic measure of exterminatus.

Discussions on what constitutes Heresy is considered Heretical; this is not because no one can come to a decision on what is heretical and not-heretical, this thought is also heretical.

Reading this definition is heretical.
Heresy is like a tree, its roots lie in the darkness whilst its leaves wave in the sun and to those who suspect nought, it has an attractive and pleasing appearance. Truly, you can prune away its branches, or even cut the tree to the ground, but it will grow up again ever the stronger and ever more comely. Yet all awhile the root grows thick and black, gnawing at the bitter soil, drawing its nourishment from the darkness, and growing even greater and more deeply entrenched.
Such is the nature of heresy, and this is why it is so hard to destroy, for it must be eradicated leaf, branch, trunk and root. It must be exorcised utterly or it will return all the stronger, time and time again, until it is too great to destroy. Then we are doomed.

Heresy is from the Greek hairesis meaning, choose, and by extension in Theological terms, "doctrines of men who have chosen to follow their own views." In general, heresy is a self-chosen doctrine not emanating from God's word. Any doctrine or teaching which is contradictory to established Church doctrine based on the Holy Bible is called a heresy.
For example, Jesus being the Son of God is established Church doctrine based on the Bible. To forsake the word and choose to believe he is not, would be heresy! back

A term used to say when someone does something against the beliefs of your culture.
For Example: BROTHER YOU DARE LEAVE THE BATTLEFIELD?! SUCH HERESY or you betray our lord with such heresy? you shall be punished for such heresy.

The act of going against the teachings of the Bible and the refusal to believe in the Almighty God. The politically correct term for this today is Atheism. This is something committed by seemingly hundreds of millions of people all over the world today. Tens of millions of people in the United States alone are heretics (the same as Atheist). The cause of all of this heresy is because of the move towards Secularism (non-religious), a more liberal culture, and the enhancement of transportation and greater communication technology, which links to everything in the outside world and the various regions of this nation.
The big cities of the Blue States are full of Heretics.

A sign used widely in theological circles denoting dodgy logic, and doctrinal unsoundness. The arm is made to look like a heron, with the lower arm held vertically to look like the neck, and the hand perpendicular to symbolise the beak.

It appears to have originated quite recently, though it has now spread all over Great Britain and is thought to have arrived in America.
"Jesus was adopted as Son later in life, right?"
Theologians shake their head and display the heresy heron.

"The Creator isn't the same guy as the Redeemer, right?"
Theologians shake their head and display the heresy heron.

A crime committed by cheap partiers in which you pay absolutely no money for alcohol/drugs, but you still manage to get more than anybody else. This is especially true when you take large amounts of alcohol from a party and bring it back to your own crib so you can throw your own party for free. You can steal individual cans and hide them in your cargo pockets, or if you are stealthy enough to get away with an unopened case that works just as well.
Tonight we will commit habitual heresy, I plan on bringing home at least a 30-Rack and a blunt.

To say something about food or restaurants that is untrue or is completely ridiculous.
Calling Olive Garden "real, authentic Italian food" is culinary heresy!
