Christensen examines ecclesiastical texts written in Nahuatl and Yucatec Maya to illustrate their role in conveying and reflecting various Catholic messages - and thus Catholicisms - throughout colonial Central Mexico and Yucatan. He demonstrates how published and unpublished sermons, confessional manuals, catechisms, and other religious texts betray 'official' and 'unofficial' versions of Catholicism, and how these versions changed throughout the colonial period according to indigenous culture, local situations, and broader early modern events.
