The GTU Guild was formed as a women's auxiliary in 1968 at the request of John Dillenberger, then President of GTU, "to support and interpret the GTU to groups in the community". An early letter of invitation to membership states: "The Guild needs people who would enjoy helping with the expansion of the membership, working with the Bibliographical Center, helping with special events, working on a speakers' bureau, guiding tours of visiting dignitaries around the seminaries, serving as a hostess, or assisting with secretarial work." Membership included wives of the heads of the participating institutions, the women members of the Board of Trustees, and lay persons from each of the denominations represented by the seminaries. In 1970, the Guild published a handbook on the GTU: The Graduate Theological Union: Its Participants and Their Ecclesiastical Heritage. They also were active in hosting receptions, providing public tours of the seminaries, offered twice yearly programs to the public, provided speakers to community and church groups, and raised donations and gave support for acquisitions to first the Bibliographical Center, then the Common Library. In 1975-76, a Guild Scholarship was founded to provide emergency funds to students with pressing needs. Though the Guild ceased to function as a group in the early 1980's, the Scholarship continues to be given irregularly.
