Title:
Teacher

Context:
There are many forms of spiritual or religious teachers in Christianity, across all three major traditions - (Roman) Catholic, (Eastern) Orthodox Catholic, and Protestant/Non-Denominational, with a stronger tradition of spiritual formation in the more historic and authoritarian/hierarchical Christian traditions with a long tradition of "discernment of spirits", of vocations, and other aspects of spiritual life, especially the Roman and Orthodox Catholic Churches. These positions include: the honoured but informal position of starets or elder - a man (or, less often, woman), often a monastic, considered to be graced by God with certain gifts for the guidance of souls and the detection and correction of prelest (spiritual pride or deception) - who acts as a spiritual guide or father in the Orthodox Catholic tradition, especially Russian Orthodoxy (see Optina Monastery, which had a long line of said starets); the Priest or Confessor in Roman Catholicism, who is often a man in Holy Orders but may be a monastic or other person respected for his spiritual accomplishments or acumen (even the Pope of Rome has a Confessor, who is not always a bishop, and, due to the hierarchical structure of the Roman Church, can not be his equal in authority), which is often a semi-official to official position, as opposed to the unofficial positions of spiritual guides in the Orthodox Catholic and Protestant traditions; and the almost-exclusively informal arrangements (generally formal only in members who are under some form of church discipline) of mentorship (both of adults and children, in the latter case often a youth pastor) in the Protestant and Non-Denominational traditions, which boundaries can be blurred with the more typically Roman "confessor" position in some of the more historic and conservative Reformation Churches, such as some of the Lutheran and Anglican. In keeping with the individualistic nature of most Protestant denominations, the emphasis on being guided in spiritual development is small, with a heavy emphasis placed on heavy reading and personal, Spirit-enlightened interpretation of the Holy Bible.
