how did Carol and Don Richardson face culture shock in a foreign culture?

The first tasks Richardson has upon moving to the jungles of Guinea are to build a house for his family and learn the previously unrecorded language of the Sawi. He then sets out to explain to them the unknown doctrines of Christianity. Richardson discovers that many Sawi traditions directly contradict these doctrines, namely the tradition of tuwi asonai man. The treachery and cannibalism of the practice idolizes characters such as Judas Iscariot, the betrayer of Jesus Christ.
