Modern revelation has restored another most important key to unlock the mystery of the almost universal knowledge of the Redeemer and of the plan of the atonement. It is found in the statement that Jesus, after his resurrection, visited at least the inhabitants of two distinct portions of the earth, which could not have been reached through the ministry of His Jewish Apostles. These two peoples were the Nephites on this land, and the Ten Tribes in their distant northern home. The knowledge that the Mexicans, and other aboriginal races of America had, at the time of their discovery by the Spaniards, of the life of the Savior, was so exact, that the Catholics suggested two theories (both incorrect, however) to solve the mystery. One was that the devil had invented an imitation gospel to delude the Indians; the other, that the Apostle Thomas had visited America and taught its people the plan of salvation. 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. Regarding this god, Humboldt writes: "How truly surprising is it to find that the Mexicans, who seem to have been unacquainted with the doctrine of the migration of the soul and the Metempsychosis _should have believed in the incarnation of the only Son of the supreme God, Tomacateuctli_. For Mexican mythology, speaking of no other Son of God, except Quetzalcoatl, who was born of Chimelman, the virgin of Tula (without man), by His breath alone, by which may be signified his word or will, when it was announced to Chimelman, by the celestial messenger, whom He dispatched to inform her that she should conceive a son, it must be presumed this was Quetzalcoatl, who was the only son. Other authors might be adduced to show that the Mexicans believe that this Quetzalcoatl was both God and man; that He had previously to His incarnation existed from eternity, and that He had been the Creator both of the world and man; and that He had descended to reform the world by endurance, and being king of Tula, was crucified for the sins of mankind, etc., as is plainly declared in the tradition of Yucatan, and mysteriously represented in the Mexican paintings."
