Mabel Ruth Williamson was an American missionary to China. She served under the auspices of the China Inland Mission, later known as the Overseas Missionary Fellowship. Have We No Rights? A frank discussion of the "rights" of missionaries is her best known work. Williamson shows the difference between suffering hardships and suffering the infringement of one's rights. She believes that as Christians we must be willing to give up the right to the comforts of life, physical health and safety, the privacy in business, friends, romance, family, and home.
