The CFC was formed in 2018 by 4 members of the United States House of Representatives: US Representatives Jared Huffman, Jamie Raskin, Jerry McNerney, and Dan Kildee. House member Pramila Jayapal joined soon after. The caucus was established in reaction to the influence of religion, especially that of the Christian right, in publicpolicy making in ways that the founders of the caucus deem inappropriate in a secular government. Such influence is seen as hampering effective and appropriate responses to issues ranging from climate change to gun violence. While Huffman has identified as a humanist without a God belief, he has indicated that the caucus is open to religious members as well who support the use of science and reason and who defend a secular government. The American Humanist Association and the Center for Freethought Equality were involved in "helping establish the caucus" by consultation. Former House of Representatives historian Ray Smock and historian of science and religion Stephen Weldon have noted what they see as the unique and historic nature of this caucus. Smock says it hearkens back to the Enlightenment ideas from the founding of the nation, and Weldon points out the political liability of being non-religious. Raskin called the caucus formation "historic", while Huffman stated the Caucus would "help spark an open dialogue about science and reason-based policy". By September 2018, the caucus had expanded by four more members and had been active in opposing the nomination of Brett Kavanaugh to the Supreme Court of the United States.

Coordinator of the Freethought Equality Fund Political Action Committee, Ron Millar, who participated in planning the caucus, stated specific aims the aforementioned PAC "wants to see", including "action against climate change"; "access to contraception and abortion"; and "maintaining" the Johnson Amendment, among others. The Congressional Freethought Caucus was unveiled by Rep. Jared Huffman during the Secular Coalition for America's annual awards dinner in Washington, DC. The Secular Coalition for America released a statement applauding the founding members of the caucus; "The formation of a Congressional Freethought Caucus is a milestone moment for nonreligious Americans in our continued struggle for inclusion in the political process and recognition as a constituency. We are living in a time when one-quarter of Americans identify as nonreligious and yet, despite these demographic changes, our community is still disparaged, stigmatized, and underrepresented in elected offices at every level of government. By proudly and unapologetically standing up for the nonreligious, these Members of Congress have struck a powerful blow against the de facto religious test that keeps so many secular Americans from seeking public office."
