Liberalism

There are those in the Church who speak of themselves as liberals who, as one of our former presidents has said: “… read by the lamp of their own conceit.” (Joseph F. Smith, Gospel Doctrine [Salt Lake City: Deseret Book Company, 1939], p. 373.) One time I asked one of our Church educational leaders how he would define a liberal in the Church. He answered in one sentence: “A liberal in the Church is merely one who does not have a testimony.”
Dr. John A. Widtsoe, former member of the Quorum of the Twelve and an eminent educator, made a statement relative to this word liberal as it applied to those in the Church. This is what he said:
“The self-called liberal [in the Church] is usually one who has broken with the fundamental principles or guiding philosophy of the group to which he belongs. … He claims membership in an organization but does not believe in its basic concepts; and sets out to reform it by changing its foundations. …
It is folly to speak of a liberal religion, if that religion claims that it rests upon unchanging truth.”
And then Dr. Widtsoe concludes his statement with this: “It is well to beware of people who go about proclaiming that they are or their churches are liberal. The probabilities are that the structure of their faith is built on sand and will not withstand the storms of truth.” (“Evidences and Reconciliations,” Improvement Era, vol. 44, p. 609.)
