While at Harvard, Knapp helped organize informal services among Christian Scientists. Initially held as receptions at the home of William P. McKenzie, prominent lecturers on Christian Science such as Edward A. Kimball of Chicago, Illinois, and Irving Tomlinson of Concord, New Hampshire, addressed these gatherings. Later after his graduation, Bliss and his cousin Edwin Johnson were instrumental in encouraging Mrs. Eddy to establish a church-sanctioned way to hold services at colleges and universities. Mrs. Eddy's response dated February 12, 1904, was a letter including her proposed changes to the By-laws of her Church known as the Manual of The Mother Church, which, with a few changes, would allow for the establishing what today are known as Christian Science College Organizations (in Article XXII Section 8). Harvard University thus became home to the first such Christian Science college organization and held the first lecture sponsored by such an organization, which was delivered by Judge Septimus J. Hanna in December 1905.
