“This work is an exciting addition to the field. It presents a source hitherto unavailable in English; it illustrates aspects of Spanish views of Andean religion that are often neglected; and it considers issues of great contemporary relevance, such as the problem of translation of Christian concepts into native languages. Both the translation and the accompanying substantial commentary are highly readable, and therefore suitable for undergraduate readers and the general reader. This is a scholarly, original, and interesting work.”—Nicholas Griffiths, University of Birmingham
