Norman Vincent Peale was a minister and author (most notably of The Power of Positive Thinking) and a progenitor of "positive thinking". His ideas were not accepted by mental health experts. Raised as a Methodist and ordained as a Methodist minister in 1922, Peale changed his religious affiliation to the Reformed Church in America in 1932 and began a 52-year tenure as pastor of Marble Collegiate Church in Manhattan. During that time the church's membership grew from 600 to over 5,000, and he became one of New York City's most famous preachers. Peale and Smiley Blanton, a psychoanalyst, established a religio-psychiatric outpatient clinic next door to the church. The two men wrote books together, notably Faith Is the Answer: A Psychiatrist and a Pastor Discuss Your Problems (1940). The book was written in alternating chapters, with Blanton writing one chapter, then Peale, and so on. Blanton espoused no particular religious point of view in his chapters. In 1951 this clinic of psychotherapy and religion grew into the American Foundation of Religion and Psychiatry, with Peale serving as president and Blanton as executive director.[2] Blanton handled difficult psychiatric cases and Peale, who had no mental health credentials, handled religious issues. Peale started a radio program, "The Art of Living," in 1935, which lasted for 54 years. Under sponsorship of the National Council of Churches he moved into television when the new medium arrived. In the meantime he had begun to edit the magazine Guideposts and to write books.
