God the Invisible King is a theological tract published by H. G. Wells in 1917. Wells describes his aim as to state "as forcibly and exactly as possible the religious belief of the writer." He distinguishes his religious beliefs from Christianity, and warns readers that he is "particularly uncompromising" on the doctrine of the Trinity, which he blames on "the violent ultimate crystallization of Nicaea." He pleads for a "modern religion" or "renascent religion" that has "no revelation and no founder."
