[3] His comics have been described by Robert Ito, in Los Angeles magazine, as "equal parts hate literature and fire-and-brimstone sermonizing".

[9] Although he did not see combat, "almost all" of the fellow servicemen he befriended were killed in action, and many of them engaged in activities such as visiting brothels.

[11] Chick credited his time overseas for inspiring him to translate his tracts into many different languages and said that he had "a special burden for missions and missionaries".

Lola Lynn Priddle (1926–1998), a Canadian immigrant, came from a very religious family, and Chick said that she was "instrumental in his salvation".

[21] After converting to Christianity, Chick wanted to evangelize others, but he was too shy to talk to people directly about religion.

[8] While working for the AstroScience Corporation (a maker of tape recorders and avionics for the U.S. government) in El Monte, California, he self-published his first tract, Why No Revival?

[8] Fred Carter illustrated tracts anonymously until 1980, when he was identified in an issue of Chick's newsletter Battle Cry.

The first eleven form the Crusader comics series, which follows the stories of two fundamentalist Christians and addresses topics such as the occult, Bible prophecy, and the theory of evolution.

[35] Chick is known for his conspiratorial views and his belief that secret groups, such as the Illuminati, exert influence on the world to advance evil.

In "The Broken Cross," Chick introduces John Todd, a former grand druid priest who claims that secret groups, including witches and the Illuminati, are working to advance evil.

Chick's version of Christianity emphasizes the role of Satan and his minions, portraying them as the principal evils in his comic.

He sees Satan as the one behind all major events, including biblical occurrences like Adam and Eve and the Great Flood, as part of his ongoing battle for control.

[36] Wiccan author Kerr Cuhulain has described Chick and his theories as being "anti-feminist" and "anti-Pagan", noted that a Chick Publications comic book was the source of a Rapid City, South Dakota police detective's presentation on the history of Satanism given in 1989, and describes him as "easily the least reputable source of reliable information on religious groups".

[42] Christianity Today described Chick as an example of "the world of ordinary, nonlearned evangelicals", for whom "atavistic anti-Catholicism remains as colorful and unmistakable as ever".

[40][45] Chick responded to these accusations by saying that he was opposed to the Roman Catholic Church as a sociopolitical organization, but not to its individual members.
