Having children, raising them, and socialization with neighbors and relatives are the greatest functions of the Amish family. Amish believe large families are a blessing from God. The main purposes of "family" can be illustrated within the Amish culture in a variety of ways. The family has authority over the individual throughout life. Loyalties to parents, grandparents, and other relatives may change over time but they will never cease. A church district is measured by the number of families (households), rather than by the number of baptized persons. Families take turns hosting the biweekly preaching service. Parents stress their responsibilities and obligations for the correct nurture of their children. They consider themselves accountable to the Lord for the spiritual welfare of their children.
