The Chaos Gods and the daemons of the Warp refer to him as " the Anathema", for he is the greatest embodiment of universal order in the galaxy today. The Emperor of Mankind is the immortal ruling monarch of the Imperium of Man, and is described by the Imperial Ecclesiarchy and the Imperial Cult as the Father, Guardian and God of humanity. He did not love His sons, He does not love men, but He does love mankind." - Roboute Guilliman, Primarch of the Ultramarines

He cannot afford affection - that is the honest practical for the impossible task that faces the Master of Mankind. Then I pray you tell me, if you are able, how such a man is anything less than a god?" - Lorgar Aurelian, Primarch of the Word Bearers "The Emperor loves no one man. If a man guides a million vessels between the infinite stars with a mere thought. If a man seeds a hundred thousand worlds with his sons and daughters, granting them custody of the galaxy itself. Summary "If a man gathers ten thousand suns in his hands. ~ The Emperor's conversation with Uriah, the last Priest on Terra, at the end of the Unification Wars And if you succeed in this grand vision of yours? What then? Beware that your subjects do not begin to see you as a god." To deny humanity a thing will only make them crave it all the more. I have seen the narrow survival path that is all that stands between humanity and extinction, and this is the way it must begin."
"Didn’t you just tell me of the bloody slaughters perpetrated by crusaders? Doesn’t that make you no better than the holy men you were telling me about?" These warriors shall be my generals and they will lead my great crusade to the furthest corners of the galaxy." These are the precursors to the warriors I am forging in my gene-labs, warriors with the strength and power and vision to bestride the battlefields of the stars and bring them to compliance. I will not conquer the galaxy with these men, for they are but men. They are powerful to be sure, but even they are not capable of such a thing." And you are arrogant if you believe you can subjugate the stars with warriors such as these. Nothing of such grand scale can be achieved without a singular vision at its heart, least of all the reconquest of the galaxy." Now that Unity has been achieved on Terra, it is time to reclaim humanity’s lost empire among the stars." A united galaxy with Terra at its heart."

An Imperium of Man that exists without recourse to gods and the supernatural.
