Samuel Johnson (10 October 1822 Salem, Massachusetts – 19 February 1882 North Andover, Massachusetts) was a United States clergyman and author.
Johnson graduated from Harvard in 1842, and from the Harvard Divinity School in 1846. He joined no religious denomination. Save for one year with a Unitarian church in Dorchester, Massachusetts, where he displeased his congregation by his opposition to slavery, he was not settled as a minister until 1853. In 1853, he established an independent society in Lynn, Massachusetts, with which he remained till 1870, when he withdrew to complete studies of many years, the results of which appeared later in his publications.
With Samuel Longfellow, Johnson compiled a Book of Hymns (1846) and Hymns of the Spirit (1864). Some of his own inspiring hymns in these books are now found in the collections of various denominations. His critical study The Worship of Jesus (1868), written in accordance with his views of universal religion, is described by O. B. Frothingham as “perhaps the most penetrating and uplifting essay on that subject in any language.” He printed notable essays on religion, reform, etc., in The Radical and other periodicals.
His great series Oriental Religions included volumes on India (1872), China (1877) and Persia (1885). The volume on Persia contains an introduction and a critical estimate of Johnson by Frothingham. The series represents what Johnson himself calls his “purely humanistic point of view.” It took its place among the most learned and liberal contributions to the study of comparative religion and civilisation. His philosophy was highly transcendental; but being versed in many languages, he was acquainted with all schools, and with the results of history, literature, science and criticism in every department.
