“The Emperor, you see, protects... He protects mankind, through the Legions, through the Martial corps, through the war machines of the Mechanicum. He understands the dangers. The inconsistencies. He uses you, and all the instruments like you, to protect us from harm. To protect our physical bodies from murder and damage, to protect our minds from madness, to protect our souls... There are insane dangers in the cosmos, dangers that mankind is fundamentally unable to comprehend, let alone survive. So he protects us. There are truths out there that would drive us mad by one fleeting glimpse of them. So he chooses not to share them with us. That's why he made you... Remember, Garviel. The Emperor is our truth and out light. If we trust in him, he will protect.”

“Great actions have shaped our society.’ Sindermann said. The greatest of these, physically, has been the Emperor's formal and complete unification of Terra, the outward sequel to which, this Great Crusade, we are now engaged upon. But the greatest, intellectually, has been our casting off of that heavy mantle called religion. Religion damned our species for thousands of years, from the lowest superstition to the highest conclaves of spiritual faith. It drove us to madness, to war,
to murder, it hung upon us like a disease, like a shackle ball. I'll tell you what religion was... No, you tell me. You, there?'
'Ignorance, sir.’
Thank you, Khanna. Ignorance. Since the earliest times, our species has striven to understand the workings of the cosmos, and where that understanding has failed, or fallen short, we have filled in the gaps, plastered over the discrepancies, with blind faith. Why does the sun go round the sky? I don't know, so I will attribute it to the efforts of a sun god with a golden chariot. Why do people die? I can't say, but I will choose to believe it is the murky business of a reaper who carries souls to some afterworld.”

“Loken took a step forward. ‘Commander,’ he said, ‘I will own up to ignorance and embrace illumination, but I will not be laughed at.”

“Regard the books,' Sinderman said,
'Are there some I should read? Will you prepare a list for me?' (asked Loken)
'Read them all. Read them again. Swallow the learning and ideas of our predecessors whole, for it can only improve you as a man...”
