Fox, George (1903). George Fox's Journal. Isbister and Company Limited. стр. 215—216. „This is the word of the Lord God to you all, and a charge to you all in the presence of the living God; be patterns, be examples in all your countries, places, islands, nations, wherever you come; that your carriage and life may preach among all sorts of people and to them: then you will come to walk cheerfully over the world, answering that of God in every one; whereby in them ye may be a blessing, and make the witness of God in them to bless you: then to the Lord God you will be a sweet savour, and a blessing.”
