- "As a theist I believe that God exists and that God creates." ~ Phillip E. Johnson
- "Even in ordinary speech we call a person unreasonable whose outlook is narrow, who is conscious of one thing only at a time, and who is consequently the prey of his own caprice, whilst we describe a person as reasonable whose outlook is comprehensive, who is capable of looking at more than one side of a question and of grasping a number of details as parts of a whole." ~ G. Dawes Hicks, The Philosophical Bases of Theism, p. 128, New York (1937).
- "I am neither Jew nor Gentile, Mahomedan nor Theist; I am but a member of the human family." ~ Frances Wright
- "I'm not a practicing Catholic or I wouldn't be living unwed with a woman, and I don't think all poofs are going to hell, and I don't think everyone who's had an abortion is damned, most of my friends are atheists and I understand atheism, I get it, but I happen to be a theist. I believe in our answerableness to something else." ~ Martin Freeman
- "It must appear impossible, that theism could, from reasoning, have been the primary religion of human race, and have afterwards, by its corruption, given birth to polytheism and to all the various superstitions of the heathen world. Reason, when obvious, prevents these corruptions: When abstruse, it keeps the principles entirely from the knowledge of the vulgar, who are alone liable to corrupt any principle or opinion." ~ David Hume, The Natural History of Religion, sect. 1, p. 312 (1898).
- "Our theism is the purification of the human mind. Man can paint, or make, or think nothing but man. He believes that the great material elements had their origin from his thought." ~ Ralph Waldo Emerson, Uses of Great Men, Representative Men (1850).
- "The only theism worthy of our respect believes in God not because of the way the world is made but in spite of that. The only theism that is no less profound than the Buddha's atheism is that represented in the Bible by Job and Jeremiah." ~ Walter Kaufmann
- "The theist and the scientist are rival interpreters of nature, the one retreats as the other advances." ~ Joseph McCabe
- "What terrible questions we are learning to ask! The former men believed in magic, by which temples, cities, and men were swallowed up, and all trace of them gone. We are coming on the secret of a magic which sweeps out of men’s minds all vestige of theism and beliefs which they and their fathers held and were framed upon." ~ Ralph Waldo Emerson, Illusions, The Conduct of Life (1860).
