We should anticipate error, otherwise error will get the advantage of us. How shall the Christian Scientist guard himself in advance?
Ask yourself what mortal mind would do to prevent Truth’s appearing in the project about to be undertaken, and then destroy the belief in its power to do anything. Know scientifically, not in a general way, that there is no M[alicious]. M[ental]. P[ractice]. to affect your patient or yourself. Mary Baker Eddy (Oakes, Richard, Lessons of the Seventh Day, p.165)
