Holiness movement
Crosby was not identified publicly with the American holiness movement of the second half of the 19th century and left no record of an experience of entire sanctification. She was, however, a fellow traveler of the Wesleyan holiness movement, including prominent members of the American Holiness movement in her circle of friends and attending Wesleyan/Holiness camp meetings. For example, she was a friend of Walter and Phoebe Palmer, "the mother of the holiness movement" and "arguably the most influential female theologian in Christian history", and their daughter Phoebe Knapp, with whom she wrote "Blessed Assurance"; she often visited the Methodist camp grounds at Ocean Grove, New Jersey, as their guest. She vacationed each summer at Ocean Grove between 1877 and 1897 (and possibly longer), where she would speak in the Great Auditorium and hold receptions in her cottage to meet her admirers.
