The basic concept of liability governs every facet of life in Chimbu (New Guinea) society. It reveals itself in major events such as marriage settlements, blood feuds, and house-building, as well as in ordinary community life, including daily meals. Once a gift has been given, the recipient has liability resting upon him until he fulfills his obligations to the giver. The foreigner who has received a “gift” of “free” services may incur the hostility of the giver if he fails to reciprocate later. This philosophy also affects Chimbu attitudes towards Christianity. When a clan feels it has paid enough for Christ's grace by attending church services and communion, it returns to its former way of life again.
