Robert Langdon: The Illuminati did not become violent until the 17th Century. Their name means 'The Enlightened Ones'. They were physicists, mathematicians, astronomers. In the 1500's they started meeting in secret, because they were concerned about the church's inaccurate teachings. They were dedicated to scientific truth. And the Vatican didn't like that. So the church began to, how did you say it? Oh, hunt them down and kill them.
Vittoria Vetra: [points to computer diagram of the antimatter device] the antimatter is suspended, there, in an airtight nano-composite shell with electromagnets on each end. But if it were to fall out of suspension, and come into contact with matter, say with the bottom of the canister, the two opposing forces would annihilate one another. Violently.
Richter: You said they'd be killed publicly.
Robert Langdon: Yes, revenge. For La Purga.
Richter: La Purga?
Robert Langdon: Oh geez, you guys don't even read your own history do you? 1668, the church kidnapped four Illuminati scientists and branded each one of them on the chest with the symbol of the cross. To 'purge' them of their sins and they executed them, threw their bodies in the street as a warning to others to stop questioning church ruling on scientific matters. They radicalized them. The Purga created a darker, more violent Illuminati, one bent on... on retribution.
Robert Langdon: I need access to the Vatican Archives.
Richter: Access to the Archives is only by written decree by the Holy Father.
Robert Langdon: Fellas, you called me.
Robert Langdon: It scares the hell out of me.
Cardinal Strauss: When you write about us, and you will, do so gently.
Cardinal Baggia: May god forgive you for what you've done...
Assassin: Father, if God has issues, they won't be with what I've done. They will be with what I'm about to do.
Inspector Olivetti: [on hearing Langdon's description of Pius IX's "Great Castration" of Vatican City's male statues] Are you anti-Catholic Mr. Langdon?
Robert Langdon: No. I'm anti-vandalism.
Cardinal Strauss: Religion is flawed because man is flawed.
[the bomb that threatens to destroy St.Peter's is set to go off at midnight. The Camerlengo is discussing evacuation with his security chief]
Camerlengo Patrick McKenna: If we are still in peril at 11.15, remove the cardinals, but in a dignified manner. I want peoples' last memory of this church to be of them walking out with their heads held high, not of some old men sneaking out the back door.
Robert Langdon: You will counsel him wisely.
Cardinal Strauss: I am an old man. I will counsel him briefly.
Camerlengo Patrick McKenna: Christianity's most sacred codices are in that archive. Given your recent entanglement with the church, there is a question I'd like to ask you first, here, in the office of His Holiness.
[Walks towards Robert Langdon]
Camerlengo Patrick McKenna: . Do you believe in God, sir?
Robert Langdon: Father, I simply believe that religion...
Camerlengo Patrick McKenna: I did not ask if you believe what man says about God. I asked if you believe in God.
Robert Langdon: I'm an academic. My mind tells me I will never understand God.
Camerlengo Patrick McKenna: And your heart?
Robert Langdon: Tells me I'm not meant to. Faith is a gift that I have yet to receive.
Camerlengo Patrick McKenna: Open the doors, and tell the world the truth.
Camerlengo Patrick McKenna: Have you come to make a martyr out of me?
Camerlengo Patrick McKenna: Our church is at war. We are under attack from an old enemy. The Illuminati. They have struck us from within and threatening us all with destruction from their new god Science.
Robert Langdon: [after suggesting a policeman not to bring him back to Vatican, but to let him save the last cardinal; the policeman turns to his colleague to confer] By all means, let's talk it over!
Camerlengo Patrick McKenna: [after breaking into Conclave and announcing that church is at war] ... but science and religion are not enemies! There are simply some things that science is just too young to understand. So the church pleads: "stop", "slow down", "think", "wait"... and for this - they call us backward. But who is more ignorant: the man who cannot define lightning, or the man who does not respect its natural awesome power?
Inspector Olivetti: The Camerlengo is unavailable. He is seeking counsel.
Robert Langdon: From whom?
Inspector Olivetti: From God.
Camerlengo Patrick McKenna: Would it surprise you to find those clothes suit you?
Robert Langdon: It would surprise the hell out of me.
Chartrand: The Catholic Church is not a corporation! It's a beacon! A source of inspiration for a billion lost and frightened souls!
Robert Langdon: Sure, I get that. It's also a bank.
Narrator: The Ring of the Fisherman, which bears the official papal seal, must be destroyed immediately following the Pope's death. The papal apartment is then sealed for nine days of mourning, a period known as "Sede Vacante", the time of the empty throne.
Lieutenant Valenti: [after dry commentary on 17th century pope's actions] Are you... anti-Catholic, professor?
Robert Langdon: No, I'm anti-vandalism.
Assassin: [on video] We will destroy your four pillars. We will brand your Preferiti and sacrifice them on the altars of science, then bring your church down upon you. Vatican City will be consumed by light, a shining star at the end of the path of illumination.
Vittoria Vetra: You know, the worst thing we thought would happen was that our work would fall into the hands of the energy companies. We thought we could change the world. So naive.
Robert Langdon: No no, not naive. Innocent maybe, but that's not a crime.
Vittoria Vetra: I'm not so sure.
Robert Langdon: Go back to work. Change the world.
Cardinal Strauss: [emphatically] Man is flawed, always. Even this one.
Cardinal Strauss: Mr. Langdon, thanks be to God for sending someone to protect His church.
Robert Langdon: I don't believe He sent me, father.
Cardinal Strauss: Oh my son, of course He did...
Camerlengo Patrick McKenna: Their faith will not protect them from an explosion.
Cardinal Strauss: We are all bound for heaven eventually, are we not?
Camerlengo Patrick McKenna: Spoken like one who has enjoyed the blessings of a long and full life.
Inspector Olivetti: Where did you get that paper?
Vittoria Vetra: We borrowed it.
Inspector Olivetti: Are you insane?
Robert Langdon: [reading paper with magnifier] "From Santi's earthly tomb with demon's hole. Cross Rome mystic elements unfold. The path of light is laid, the sacred test. Let angels guide thee on they lofty quest."
Inspector Olivetti: You removed a document from the Vatican Archives?
Robert Langdon: [points at Vittoria] She did.
Robert Langdon: Do you smoke?
Chartrand: A little bit.
Robert Langdon: Then you better sit down before you keel over.
Assassin: If it were up to me it would not be this way. It is a sin to kill the pain. It is a sin to kill without reason. Father, they make me a sinner.
Assassin: You know, when they call me, and they all call me, it is so important to them that I know what they ask is the Lord's will. Or Allah's or Yahweh's. And I suppose they're right. 'Cause if he was not vengeful, I would not exist, now would I?
