In his later years, Geronimo embraced Christianity, and stated, "Since my life as a prisoner has begun I have heard the teachings of the white man's religion, and in many respects believe it to be better than the religion of my fathers ... Believing that in a wise way it is good to go to church, and that associating with Christians would improve my character, I have adopted the Christian religion. I believe that the church has helped me much during the short time I have been a member. I am not ashamed to be a Christian, and I am glad to know that the President of the United States is a Christian, for without the help of the Almighty I do not think he could rightly judge in ruling so many people. I have advised all of my people who are not Christians, to study that religion, because it seems to me the best religion in enabling one to live right."[11] He joined the Dutch Reformed Church in 1903 but four years later was expelled for gambling.[11] To the end of his life, he seemed to harbor ambivalent religious feelings, telling the Christian missionaries at a summer camp meeting in 1908 that he wanted to start over, while at the same time telling his tribesmen that he held to the old Apache religion.
