During his trial, Kenyatta described himself as a Christian saying, "I do not follow any particular denomination. I believe in Christianity as a whole." Arnold stated that in England, Kenyatta's adherence to Christianity was "desultory". While in London, Kenyatta had taken an interest in the atheist speakers at Speakers' Corner in Hyde Park, while an Irish Muslim friend had unsuccessfully urged Kenyatta to convert to Islam. During his imprisonment, Kenyatta read up on Islam, Hinduism, Buddhism, and Confucianism through books supplied to him by Stock. The Israeli diplomat Asher Naim visited him in this period, noting that although Kenyatta was "not a religious man, he was appreciative of the Bible". Despite portraying himself as a Christian, he found the attitudes of many European missionaries intolerable, in particular their readiness to see everything African as evil. In "Facing Mount Kenya", he challenged the missionaries' dismissive attitude toward ancestor veneration, which he instead preferred to call "ancestor communion". In that book's dedication, Kenyatta invoked "ancestral spirits" as part of "the Fight for African Freedom."
