“I would stand with God against man, rather than with man against God.”

§ IV
1910s, At the Feet of the Master (1911)
Context: Of all the Qualifications, Love is the most important, for if it is strong enough in a man, it forces him to acquire all the rest, and all the rest without it would never be sufficient. Often it is translated as an intense desire for liberation from the round of births and deaths, and for union with God. But to put it in that way sounds selfish, and gives only part of the meaning. It is not so much desire as will, resolve, determination. To produce its result, this resolve must fill your whole nature, so as to leave no room for any other feeling. It is indeed the will to be one with God, not in order that you may escape from weariness and suffering, but in order that because of your deep love for Him you may act with Him and as He does. Because He is Love, you, if you would become one with Him, must be filled with perfect unselfishness and love also.
In daily life this means two things; first, that you shall be careful to do no hurt to any living thing; second, that you shall always be watching for an opportunity to help.
First, to do no hurt. Three sins there are which work more harm than all else in the world — gossip, cruelty, and superstition — because they are sins against love. Against these three the man who would fill his heart with the love of God must watch ceaselessly.

The Devil and the Good Lord (1951)

On members of the clergy who sought to establish some form of "official" Christianity in the U.S. government. Letter to Dr. Benjamin Rush (23 September 1800)
This has commonly been quoted as "I have sworn upon the altar of God Eternal, hostility against every form of tyranny over the mind of man", "I have sworn upon the altar of God eternal hostility against every form of tyranny over the mind of man", and "I have sworn upon the altar of God, eternal hostility against every form of tyranny over the mind of man." Neither capitalization of "god" and "eternal", nor a comma before or after "eternal" are apparent in the original.

The first portion of this statement has also been widely paraphrased as "The clergy believe that any power confided in me will be exerted in opposition to their schemes, and they believe rightly".
1800s
Context: The returning good sense of our country threatens abortion to their hopes, & they believe that any portion of power confided to me, will be exerted in opposition to their schemes. And they believe rightly; for I have sworn upon the altar of god eternal hostility against every form of tyranny over the mind of man. But this is all they have to fear from me: and enough, too, in their opinion.

canular refers to hoaxes, humorous deceptions.
The Paris Review interview (1984)
Context: You know, the Cathars believed that the world was not created by God but by a demon who had stolen a few technological secrets from Him and made this world — which is why it doesn’t work. I don’t share this heresy. I’m too afraid! But I put it in a play called This Extraordinary Brothel, in which the protagonist doesn’t talk at all. There is a revolution, everybody kills everybody else, and he doesn’t understand. But at the very end, he speaks for the first time. He points his finger towards the sky and shakes it at God, saying, “You rogue! You little rogue!” and he bursts out laughing. He understands that the world is an enormous farce, a canular played by God against man, and that he has to play God’s game and laugh about it.
