In 1991, Dr. Keefe applied for and received a grant from the ACLS that enabled her to spend another summer in European libraries for a new project, which she was calling "The Education of a Christendom." She would continue to develop this project for the next twenty years, eventually publishing her research as The Making of Christendom. This was to be a study of medieval commentaries on the creeds. She began with the list of manuscripts published by Nicholas M. Haring in his article, "Commentaries on the Pseudo-Athanasian Creed," Medieval Studies 34 (1972): 208–52. One of her many questions was whether "Carolingian creed commentaries that originated in, or circulated in, the same area, express similar interpretations of the faith, possibly also same local concerns with [heresies such as] Apollinarianism [or theological themes such as] predestination, etc.? I.e., can we find geographical differences in the teaching of the faith?"1
