Leo Tolstoy 
My Religion [EPUB ebook] 

Raised in the Russian Orthodox Church, Tolstoy lost his religion at 18. After a life of debauchery, in his early 50s, he wanted religion — or some source of intellectual security — back. Tolstoy notes that, whatever the faith may be,  it “gives to the finite existence of man an infinite meaning, a meaning not destroyed by sufferings, deprivations, or death, ” and yet he is careful not to conflate faith with a specific religion. Tolstoy believed being a Christian required him to be a pacifist; the apparently inevitable waging of war by governments, is why he is considered a philosophical anarchist.
