⁷ Religion per se factors only secondarily in scholarship on the Nicholses, which tends to focus on their social reforms.

¹⁰⁸ Clark, A Luminous Brotherhood, 84–98; and Daggett, Spiritualism in Nineteenth-Century New Orleans, 88–90, 103–104. Carroll also notes similarities between Spiritualism and Catholicism. He argues that Spiritualists’ well-ordered spiritual realm and structured religious practice constituted a reaction to individualist Protestantism akin to the Oxford Movement or the Catholic conversions of Orestes Brownson and Isaac Hecker. Carroll, Spiritualism in Antebellum America, 80. Similarly, reflecting on the thread of liberal Christianity that ran through Spiritualism, Albanese concludes that “the anti-Christian reputation of Spiritualism seems overblown. For all the hostility toward organized sects and churches, the spirit messages were ambiguous—and decidedly combinative.” Albanese, A Republic of Mind and Spirit, 228–233.

To be sure, an emotional consonance undergirded these rhetorical moves. Catholics derived comfort from their connection to Christians past and present, whether as a source of grace or as consolation in the face of loss. Taves, The Household of Faith, 47–56. Likewise, many people, including the Nicholses, turned to Spiritualism in bereavement. Nichols, Nichols’ Health Manual, 108.

¹³² Quoted in Thurston, The Church and Spiritualism, 55–56.

¹³³ In 1933, the Jesuit scholar Herbert Thurston echoed the Nicholses’ arguments, noting the similarities between Spiritualism and “such well-known Catholic tenets as the belief in miracles, in purgatory, and in the revelations made to holy people,” as well as Spiritualism's “value as a weapon against crude materialism.” Thurston identified “a distinct Romeward trend” among religiously-minded Spiritualists. Ibid., 46, 143, 46. By and large, scholars have not followed up on Thurston's suggestion. Spiritualism is not considered as an avenue to Catholicism in the recent issue of the U.S. Catholic Historian dedicated to Catholic conversions (volume 32, number 4) nor in Franchot's Roads to Rome or Allitt's Catholic Converts. Among historians who note something like a “Romeward trend,” Aspinwall lists a few Catholics who were sympathetic to Spiritualism, Carroll notes that John Shoebridge Williams was “impressed” by the spirit of his daughter to attend Catholic mass, and Alison Winter reports that, in Britain, “Lord Shrewsbury and Lord Stanhope, both Catholic sympathizers, collected stories of conversions to Catholicism involving what they saw as supernatural trance states.” Aspinwall, “Social Catholicism and Health,” 261–263; Carroll, Spiritualism in Antebellum America, 80; and Winter, Alison, Mesmerized: Powers of Mind in Victorian Britain (Chicago: University of Chicago Press, 1998), 267Google Scholar.

See, for example, “Free Lovers Converted to Catholicism,” Chicago Daily Tribune, April 7, 1857.

¹³⁶ British Spiritualist, Theosophist, and social reformer Anna Kingsford may count as another. She converted to Catholicism in 1870 upon “her receipt of nocturnal visitations, three in number, from an apparition purporting to be that of St. Mary Magdalen.” She apparently maintained her Catholicism throughout her life, although she criticized the church for not endorsing the anti-vivisection movement and described her beliefs as “pantheist.” Maitland, Edward, Anna Kingsford: Her Life, Letters, Diary, and Work, 2nd ed., vol. 1 (London: George Redway, 1896), 15–16Google Scholar, 324–325, 27–28.
