"You say that you are right and we are lost. How do we know this to be true? We understand that your religion is written in a book. If it was intended for us as well as for you, why has not the Great Spirit given it to us; and not only to us, but why did he not give to our forefathers the knowledge of that book, with the means of understanding it rightly? We only know what you tell us about it. How shall we know when to believe being so often deceived by the white people? Brother! You say there is but one way to worship and serve the Great Spirit. If there is but one religion, why do you white people differ so much about it? Why do you not all agree, as you read the book?"
