What an excellent day for an exorcism.
– Demon
You would like that?
– Father Karras
Intensely.
– Demon
But wouldn’t that drive you out of Regan?
– Father Karras
It would bring us together.
– Demon
You and Regan?
– Father Karras
You and us.
– Demon

The Power of Christ compels you!
– Father Merrin, Father Karras

Your mother sucks cocks in Hell, Karras, you faithless slime.
– Demon

Why her? Why this girl?
– Father Karras
I think the point is to make us despair. To see ourselves as… animal and ugly. To make us reject the possibility that God could love us.
– Father Merrin

Do you know what she did, your cunting daughter?
– Demon

Stick your cock up her ass, you motherfucking worthless cocksucker.
– Demon

You’re going to die up there.
– Regan

Especially important is the warning to avoid conversations with the demon. We may ask what is relevant but anything beyond that is dangerous. He is a liar. The demon is a liar. He will lie to confuse us. But he will also mix lies with the truth to attack us. The attack is psychological, Damien, and powerful. So don’t listen to him. Remember that – do not listen.
– Father Merrin

Let Jesus fuck you, let Jesus fuck you. Let him fuck you.
– Demon

I’m not Regan.
– Demon
Well, then let’s introduce ourselves. I’m Damien Karras.
– Father Karras
And I’m the Devil. Now kindly undo these straps.
– Demon
If you’re the Devil, why not make the straps disappear?
– Father Karras
That’s much too vulgar a display of power, Karras.
– Demon

What are you doing here?
– Chris MacNeil
My bed was shaking. I can’t get to sleep.
– Regan

You killed your mother! You left her alone to die! Bastard!
– Demon
Shut up!
– Father Karras

Cunting Hun! Bloody damn butchering Nazi pig!
– Burke Dennings

I think it might be helpful if I gave you some background on the different personalities Regan has manifested. So far, I’d say there seem to be three. She’s convinced…
– Father Karras
There is only one.
– Father Merrin

Where is Regan?
– Father Karras
In here. With us.
– Demon

Your mother’s in here, Karras. Would you like to leave a message? I’ll see that she gets it.
– Demon

Lick me, lick me!
– Demon

How do you go about getting an exorcism?
– Chris MacNeil
I beg your pardon?
– Father Karras

Would you like some bourbon in that, father?
– Chris MacNeil
Well, my doctor says I shouldn’t but thank God my will is weak.
– Father Merrin
