A confraternity (; ) is generally a Christian voluntary association of laypeople created for the purpose of promoting special works of Christian charity or piety, and approved by the Church hierarchy. They are most common among Catholics, Lutherans, Anglicans, and the Western Orthodox. When a Catholic confraternity has received the authority to aggregate to itself groups erected in other localities, it is called an archconfraternity. Examples include the various confraternities of penitents and the confraternities of the cord, as well as the Confraternity of the Holy Guardian Angels and the Confraternity of the Rosary.
