According to Richardson, Richardson and Bentley, the Book of Mormon teaches that the Godhead consists of three separate and distinct beings, "God the Father, and also the Lord Jesus Christ, and the Holy Ghost" (Ether 12:41). This correlates very well with the beliefs of Mesoamerica.
In ancient American theology, the earth was created by a Godhead of three distinct personages:
"then they planned the creation, and the growth of the trees and the thickets and the birth of life and the creation of man. Thus it was arranged in the darkness and in the night by the Heart of Heaven who is called Huracan. The first is called Caculha Huracan. The second is Chipi-Caculha. The third is Raxa-Caculha. And these three are the Heart of Heaven." Chipi-Caculha is also referred to as, Gucumatz and is identified with the Fair God--Quetzalcoatl. (Franklin S. Harris, Jr., The Book of Mormon: Messages and Evidences, pp. 76-78)
Peter DeRoo writes the following in his work, History of America Before Columbus (1900), vol. 1, p. 372:
The natives of Campeche assured the Spanish missionaries that their religious teacher, Quetzalcoatl had given them images to explain his doctrine, and, in particular, a triangular stone, as an illustration of the Blessed Trinity, with which mystery they were well acquainted, says Sahagun, and in whose name they were baptized.
DeRoo goes on to tell of the Quiche trinity in Guatemala called "Tohil, Awilix, and Gucumatz," and the Chiapan trinity called "Icona, Bacab and Echuac."
