TritheismTritheism (from Greek τριθεΐα, "three divinity") is a nontrinitarian Christian heresy in which the unity of the Trinity and thus monotheism are denied. It represents more a "possible deviation" than any actual school of thought positing three separate deities. It was usually "little more than a hostile label" applied to those who emphasized the individuality of each hypostasis or divine person—Father, Son and Holy Spirit—over the unity of the Trinity as a whole. The accusation was especially popular between the 3rd and 7th centuries AD.
MonothelitismMonothelitism, or monotheletism (from monothelētismós), is a theological doctrine in Christianity, that holds Christ as having only one will. The doctrine is thus contrary to dyothelitism, a Christological doctrine that holds Christ as having two wills (divine and human). Historically, monothelitism was closely related to monoenergism, a theological doctrine that holds Jesus Christ as having only one Energeia/Nature. Both doctrines were at the center of Christological disputes during the 7th century.
KemetismKemetism (also Kemeticism; both from the Egyptian kmt, usually voweled Kemet, the native name of ancient Egypt), also sometimes referred to as Neterism (from nṯr (Coptic ⲛⲟⲩⲧⲉ noute) "deity"), or Kemetic paganism, is a neopagan religion and revival of the ancient Egyptian religion and related expressions of religion in classical and late antiquity, emerging during the 1970s. A Kemetic or Kemetic pagan is one who follows Kemetism.
Religious liberalismReligious liberalism is a conception of religion (or of a particular religion) which emphasizes personal and group liberty and rationality. It is an attitude towards one's own religion (as opposed to criticism of religion from a secular position, and as opposed to criticism of a religion other than one's own) which contrasts with a traditionalist or orthodox approach, and it is directly opposed by trends of religious fundamentalism.
Book of ConcordThe Book of Concord (1580) or Concordia (often referred to as the Lutheran Confessions) is the historic doctrinal standard of the Lutheran Church, consisting of ten credal documents recognized as authoritative in Lutheranism since the 16th century. They are also known as the symbolical books of the Evangelical Lutheran Church. The Book of Concord was published in German on June 25, 1580, in Dresden, the fiftieth anniversary of the presentation of the Augsburg Confession to Emperor Charles V at the Diet of Augsburg.
