Cosmology

The cosmological view in mesoamerica is strongly connected to the mesoamerican gods and the spiritual world. You may say that the construction and division of the universe, therefore is a kind of visual and symbolic set up for their religious beliefs.
Like the many different peoples of mesoamerica, the detailed surface of the cosmological views tends to be many. They all come together though, in the belief of a fundamental cosmic order, in which the two elements of time and space are the most important. These two elements are seen as the center of the universe and make the center of the quadriplicity, known as the mesoamerican world tree quite close to the quincunx

Time and space

The importance of time is seen in the cycles of life, death and regeneration, which are something worshiped in almost everything existing. Time itself, is symbolised in the cycle of the sun, both because the sun separates night and day, and also because the death and regeneration of the sun itself is the reason for a new era.

As an expansion of quincunx, which then symbolises space, we find two axes that combine the universe with the inclusion of both the natural and the spiritual, vertically and horizontally. It is the so called ’axis mundi

Axis mundi

The axis mundi , in religion or mythology, is the world center and/or the connection between heaven and Earth. As the celestial pole and geographic pole, it expresses a point of connection between sky and earth where the four compass directions meet...

’, which in the case of mesoamerican cosmology, vertically consists of three worlds and horizontally of four directions and a center.
In the vertical axis we find the world that we know on the surface of earth, in the middle a world above us where the stars are seen and then a world below our surface. These three worlds are not to be confused with the Christian division of a heaven and a hell, although the Spaniards, in trying to convert the native mesoamerican, made the two comparable by doing so.

Colonized Mesoamerica

When the Spanish came to Mesoamerica, they caused a severe disruption of Aztec values by tearing down their temples, smashing their idols, displacing the native priesthood and abolishing human sacrifice. This eventually led to the abandonment of the fundamental belief that the successful functioning of the universe depended on human propitiation of the gods.
War and human sacrifice had been some of the focal values in Aztec religion before the conquest. War provided sacrificial victims needed to feed and thereby propitiate the gods, who in return gave rain, sun, crops and all the necessities of life. In particular Huitzilopochtli, the supreme god of the Aztecs, needed huge meals of human blood and hearts to be able to fight the daily battle with the forces of darkness. Without these meals it was feared that he would plunge the world into darkness.

When the Spanish besieged Tenochtitlan, the Aztecs fought back and sacrificed their white captives to Huitzilopochtli, but in spite of this the god of war failed to defeat the Spanish. And even though the Aztecs continued to worship some of their own gods after the conquest, the cult of the war god was dead. The belief in the protection of Huitzilopochtli had been destroyed by the Spanish.

The early friars in the colonized Mesoamerica wrote manuals describing indigenous rituals and practices, to define what was acceptable and unacceptable, and to recognize the unacceptable when they saw it. But these observations were very subjective. And the things considered to be connected to the Devil varied depending on the person who wrote the manual.

Missionaries in Mesoamerica attempted to take already existing symbols and elements in the local indigenous religions and societies, and give them Christian meaning and symbolism. E.g. The Mesoamerican world tree, which they interpreted as a cross. But at the same time they also demonized other elements, which were considered to not comply with Christian beliefs. They did this to make it easier to convert the Mesoamericans to Christianity.

Before the Spanish conquest each village had a patron deity whose idol were worshipped, presented with offerings and adorned with jewelry and fine robes. After the conquest each village got in its place a Catholic patron saint whose image was adorned and worshipped like before.
And destinations of pilgrimage where the indigenous peoples used to worship gods before the conquest, were adapted to Catholic saints like the Señor de Chalma (Chalma, Malinalco, Mexico State

The Aztecs and the Maya shared many religious elements before the Spanish conquest, but reacted very differently to the same form of Spanish Catholicism. The Aztecs abandoned their rites and merged their own religious beliefs with Catholicism, whereas the Maya kept their religion as the core of their beliefs and incorporated varying degrees of Catholicism.
The Aztec village religion was supervised by friars, mainly Franciscan

. Prestige and honor in the village were achieved by holding office within the religious organizations.
It was not possible for the indigenous to enter the Orders or receive sacramental ordination as secular priests.

Greatly aiding the early missionaries was the image known as the Virgen de Guadalupe.

From the 17th centuries on, Spanish clergy had very little to do with religious development in most Mexican villages and this gave free rein to Aztec religious syncretism. )
