Semipelagianism
Semi-Pelagianism (or semipelagianism) is a historical Christian theological and soteriological school of thought about the role of free will in salvation. In semi-Pelagian thought, a distinction is made between the beginning of faith and the increase of faith. Semi-Pelagian thought teaches that the latter half – growing in faith – is the work of God, while the beginning of faith is an act of free will, with grace supervening only later.

demythologization
Demythologization as a hermeneutic approach to religious texts seeks to separate or recover cosmological, sociological and historic claims from philosophical, ethical and theological teachings. Mostly applied to biblical texts, demythologization often overlaps with philology, biblical criticism and form criticism. The term demythologization (in German: Entmythologisierung) was introduced by Rudolf Bultmann (1884–1976) in existential context, but the concept has earlier precedents.

Panbabylonism

Panbabylonism (also known as Panbabylonianism) was the school of thought that considered the cultures and religions of the Middle East and civilization in general to be ultimately derived from Babylonian myths which in turn they viewed as being based on Babylonian astronomy, often in hidden ways.

Quartodecimanism
Quartodecimanism (from the Vulgate Latin quarta decima in Leviticus 23:5, meaning fourteenth) is the name given to the practice of commemorating the death of Christ on the day of Passover, the 14th of Nisan according to biblical dating, on whatever day of the week it occurs. The Quartodeciman controversy in the Church was the question of whether to celebrate Easter on Sunday (the first day of the week), or at the time of sacrifice of the Passover lamb.

The Kollyvades () were the members of a movement within the Eastern Orthodox Church that began in the second half of the eighteenth century among the monastic community of Mount Athos, which was concerned with the restoration of traditional practices and opposition to unwarranted innovations, and which turned unexpectedly into a movement of spiritual regeneration. As Metropolitan Kallistos Ware succinctly points out:
