) During the
Age of Discovery, 1450–1700, Iberian rulers took a great interest in the missionary evangelization of indigenous peoples encountered in newly discovered lands. In Catholic Spain and Portugal, the missionary project was funded by Catholic monarchs under the
patronato real issued by the pope to ensure Catholic missionary work was part of a broader project of conquest and colonization. The decades after the Spanish conquest witnessed a dramatic transformation of indigenous culture, a transformation with a religious dimension that contributed to the creation of Mexican culture. People from both the Spanish and indigenous cultures held a wide range of opinions and views about what was happening in this transformation. The evangelization of New Spain was led by Franciscan, Dominican and Augustinian friars. These religious orders established the Catholic Church in colonial New Spain, and directed it during most of the 16th century. The Franciscans in particular were enthusiastic about the new land and its people. Franciscan friars who went to the New World were motivated by a desire to preach the Gospel to new peoples. Many Franciscans were convinced that there was great religious meaning in the discovery and evangelization of these new peoples. They were astonished that such new peoples existed and believed that preaching to them would bring about the return of Christ and the end of time, a set of beliefs called
millenarianism. Concurrently, many of the friars were discontented with the corruption of European society, including, at times, the leadership of the Catholic Church. They believed that New Spain was the opportunity to revive the pure spirit of primitive Christianity. During the first decades of the Spanish conquest of
Mesoamerica, many indigenous people converted to Christianity, at least superficially. The friars employed a large number of indigenous Americans for the construction of churches and monasteries, not only for the construction itself, but also as artists, painters and sculptors, and their works were used for decoration and evangelization. In this process, the native artists added many references to their customs and beliefs: flowers, birds or geometric symbols. Friars thought the images were decorative, but the Natives recognized their strong religious connotation. The mixture of Christian and Indian symbols has been described as
Indocristiano or
Indochristian art. Inspired by their Franciscan spirituality and Catholic humanism, the friars organized the indigenous peoples into
utopian communities. There were massive waves of indigenous peoples converting to Catholicism, as measured by hundreds of thousands of baptisms in massive evangelization centers set up by the friars. In its initial stages, the colonial evangelization project appeared quite successful, despite the sometimes antagonizing behavior of the conquistadores. However, the indigenous people did not express their Christian faith in the ways expected by the missionary friars. Many still practiced their pre-European contact religious rituals and maintained their ancestral beliefs, much as they had for hundreds or thousands of years, while also participating in Catholic worship, a practice known as
multiple religious belonging. The friars had disagreements over how best to approach this problem, as well as disagreements about their mission, and how to determine success. ==At the Colegio de Santa Cruz de Tlatelolco==
