Episcopal Church theologian and later bishop, John M. Krumm, criticized Peale and the "heretical character" of his teaching on positive thinking. Krumm cites "the emphasis upon techniques such as the repetition of confident phrases ... or the manipulation of certain mechanical devices", which he says "gives the impression of a thoroughly depersonalized religion. Very little is said about the sovereign mind and purpose of God; much is made of the things men can say to themselves and can do to bring about their ambitions and purposes." Krumm cautions that "The predominant use of impersonal symbols for God is a serious and dangerous invitation to regard man as the center of reality and the Divine Reality as an impersonal power, the use and purpose of which is determined by the man who takes hold of it and employs it as he thinks best."
