Since its publication, Luis Laso de la Vega’s foundational text, Huei tlamahuiçoltica (1649), continues to influence Guadalupan devotion but has only recently been examined as a theological and pastoral work. Still missing from these treatments is a discussion of the significance of the text’s genre, hagiography. This paper continues to draw out the theological and pastoral depth of Huei tlamahuiçoltica, specifically as the first Guadalupan hagiography. Moreover, it argues for the text to be considered a communal hagiography of sixteenth-century Nahuas that seeks to shape Nahua-Christian identity through Guadalupan devotion.
