Because of the social mobility of Christians, the religion has had an impact incommensurate with its size and has affected the family ethics not only of its own adherents but also those of non-Christians. Generally, it has loosened the requirements of Confucian tradition and realized a democratization of family culture. This process has not been without challenges, in particular, because the line separating Christians from non-Christians may run right through families. The performance of memorial services for the family ancestors can be a real bone of contention. A large number of Christians reject these rituals as a form of ancestor worship, which they consider idolatrous. This rejection can be very offensive to those devoted to observing the traditional rites. Often, tedious negotiations result in some form of compromise, with, for example, the Christian relatives offering a prayer and the Confucian members of the family bowing at the ancestral gravesite. These are no simple disputes but often involve profound soul-searching and serious family discussion.
