The Amish, whose religion is a denomination of Anabaptist Christianity, believe large families are a blessing from God. Amish rules allow marrying only between members of the Amish Church. Older people do not go to a retirement facility; they remain at home. As time passed, the Amish felt pressure from the modern world; their traditional rural way of life became more different from modern society. Isolated groups of Amish populations may have genetic disorders or other problems associated with closed communities. Amish make decisions about health, education, and relationships based on their Biblical interpretation. Amish life has influenced some things in popular culture. As the Amish are divided into the Old Order Amish, New Order Amish, and Beachy Amish, the way of life of families depends on the rule of the church community to which they belong.
