A religious name is a type of given name bestowed for a religious purpose, and which is generally used in religious contexts. Different types of religious names may be in use among clergy of a religion, as well in some cases among the laity.
In baptism, Catholics are given a Christian name, which should not be "foreign to Christian sentiment" and is often the name of a saint. In East Asia, in Africa and elsewhere, the baptismal name is distinct from the traditional-style given name.
Confirmation name
In some countries, it is common to adopt a confirmation name, in addition to the baptismal name.
In some religious institutes, a new member takes a religious name. In Italian, a religious figure is often referred to by their religious name and by their secular name or their :it:al secolo|al secolo name. A newly electedPope also takes on a new name, called his regnal name or papal name.
Eastern Church
Baptism name
In the Eastern Orthodox Church and Eastern Catholicism converts often take a new name at the time of their reception into the church, either by baptism or chrismation. A person's religious name is always the name of a saint, who then becomes that person's patron saint. When deciding on a name for their child, Orthodox parents will often name the child after a saint whose feast day falls on either the day of the child's birth or the day of its baptism. Traditionally, Orthodox Christians celebrate their "name day", rather than their birthday.
Monastic name
Catholic and Orthodox monks and nuns are often given a new monastic name at the time of their tonsure. A monastic name is usually the name of a prophet or a monastic saint. Sometimes, the monastic name will begin with the same initial as the individual's baptismal name.
Judaism
take a Hebrew name upon conversion. Born Jews generally have a patronymic Hebrew name which is used for religious purposes; this is frequently different from their legal name, especially when the latter is of gentile or non-Hebrew origin.
Buddhism
Many Buddhist sects also practice this, with newly ordained sangha often given new names by their master. Lay Buddhists are also given Dharma names during their refuge ceremony.
Hinduism
Gaudiya Vaishnavism
Members of ISKCON and some other Gaudiya Vaishnava organisations are given a "spiritual name" by their guru upon initiation. This name ends in "Das" or "Dasa" for men and "Dasi" for women, and generally begins with the same letter as the devotee's given name.
