Some forty years ago, Frederic J. Turner, the eminent American historian, called attention to the fact that the religious life of the frontier has not been sufficiently investigated. Since then, much important work in this field has been done. One aspect of the religious life of the frontier, however, has been almost entirely neglected, that of Swedenborgianism, or, as followers of the Swedish prophet prefer to say, that of the New Church. Emanuel Swedenborg was born in Stockholm in 1688. Since we are approaching the two hundred fiftieth anniversary of his birth, now is an opportune time to investigate a hitherto neglected influence, very potent on the American frontier during the nineteenth century.
