Extract from a Sermon delivered in Boston, January 18, 1885
Text: The kingdom of heaven is like unto leaven, which a woman took, and hid in three measures of meal, till the whole was leavened. — Matt. xiii. 33.
Few people at present know aught of the Science of mental healing; and so many are obtruding upon the public attention their ignorance or false knowledge in the name of Science, that it behooves all clad in the shining mail to keep bright their invincible armor; to keep their demonstrations modest, and their claims and lives steadfast in Truth. (Eddy, Mary Baker, Miscellaneous Writings, p. 171:21-2)
