An elder (in Greek, πρεσβυτερος [presbyteros]; see Presbyter) in Christianity is a person valued for his wisdom who accordingly holds a particular position of responsibility in a Christian group. In some Christian traditions (e.g., Eastern Orthodoxy, Roman Catholicism, Anglicanism, Methodism) an elder is a clergy person who usually serves a local church or churches and who has been ordained to a ministry of Word, Sacrament, and Order, filling the preaching and pastoral offices. In other Christian traditions (e.g. Presbyterianism, Baptists), an elder may be a lay person charged with serving as an administrator in a local church, or be ordained to such an office. However, elders exist throughout world cultures.
