A dangerous cult brings fear, misery and threatens death to the Nahuatl people.

Little Samuel was normally a chubby toddler.

But there he laid in the local clinic, missionary Rachel Chapman says, a 20-month-old boy who was severely dehydrated and malnourished.

Samuel had a stomach bug for a month. He had been unable to keep food or liquids down for some time. “He was just skin and bones,” Rachel writes.

The doctors were able to rehydrate the little boy and fed him atole, a type of gruel made from blended grains. The next day, they took Samuel and his parents to a hospital.

Rachel says that Samuel’s parents are blankos, or “white ones.” They are part of a group of people who began claim some months back that they had received special revelation from God.
