Among the Aztecs, whose beliefs are the best-documented in the historical sources, Quetzalcoatl was associated with the God of the Wind, of the planet Venus, of the Dawn, and of Knowledge.

Similar attributes are found with the biblical Christ and Enlil.

To the Aztecs, Quetzalcoatl was, as his name indicates, a feathered serpent, a flying reptile (much like a dragon), who was a boundary-maker (and transgressor) between earth and sky. He was a creator deity having contributed essentially to the creation of Mankind. He also had anthropomorphic forms, for example in his aspects as Ehecatl the wind god. Among the Aztecs, the name Quetzalcoatl was also a priestly title, as the two most important priests of the Aztec Templo Mayor were called "Quetzalcoatl Tlamacazqui".

Some Mormons believe that Quetzalcoatl was historically Jesus Christ, but believe His name and the details of the event were gradually lost over time. According to the Book of Mormon, the resurrected Christ came down from the clouds and visited the people of the American continent, shortly after his resurrection.

The story of the life of the Mexican divinity, Quetzalcoatl, closely resembles that of the Savior; so closely, indeed, that we can come to no other conclusion than that Quetzalcoatl and Christ are the same being. But the history of the former has been handed down to us through an impure Lamanitish source, which has sadly disfigured and perverted the original incidents and teachings of the Savior's life and ministry."
