Believer's baptism or adult baptism is the practice of baptizing those who are able to make a conscious profession of faith, as contrasted to the practice of baptizing infants. Credobaptists believe that infants incapable of consciously believing should not be baptized.

The Amish, formally the Old Order Amish, are a group of traditionalist Anabaptist Christian church fellowships with Swiss German and Alsatian origins. As they maintain a degree of separation from surrounding populations, and hold their faith in common, the Amish have been described by certain scholars as an ethnoreligious group, combining features of an ethnicity and a Christian denomination. The Amish are closely related to Old Order Mennonites and Conservative Mennonites—denominations that are also a part of Anabaptist Christianity. The Amish are known for simple living, plain dress, Christian pacifism, and slowness to adopt many conveniences of modern technology, with a view neither to interrupt family time, nor replace face-to-face conversations whenever possible, and a view to maintain self-sufficiency. The Amish value rural life, manual labor, humility and Gelassenheit.
