baptized in the Nicene faith being Theodosius the Great, emperor from 379 to 395. Nontrinitarian Christian beliefs Nontrinitarianism (or antitrinitarianism) refers to Christian belief systems that reject the doctrine of the Trinity as found in the Nicene Creed as not having a scriptural origin. Nontrinitarian views differ widely on the nature of God, Jesus, and the Holy Spirit. Various nontrinitarian views, such as Adoptionism, Monarchianism, and Arianism existed prior to the formal definition of the Trinity doctrine in AD 325, 360, and 431, at the Councils of Nicaea, Constantinople, and Ephesus, respectively. Following the adoption of trinitarianism at Constantinople in 381, Arianism was driven from the Empire, retaining a foothold amongst the Germanic tribes. When the Franks converted to Catholicism in 496, however, it gradually faded out. Nontrinitarianism was later renewed in the Gnosticism of the Cathars in the 11th through 13th centuries, in the Age of Enlightenment of the 18th century, and in some groups arising during the Second Great Awakening of the 19th century.

Adoptionism was declared as heretical by the Ecumenical Council of Frankfurt, convened by the Emperor Charlemagne in 794 for the Latin West Church. Modern nontrinitarian groups or denominations include Christadelphians, Christian Science, the Church of Jesus Christ of Latter-day Saints, Dawn Bible Students, Iglesia ni Cristo, Jehovah's Witnesses, Living Church of God, Members Church of God International, Oneness Pentecostals, La Luz del Mundo, the Seventh Day Church of God, Unitarian Christians, United Church of God, and The Shepherd's Chapel. As pointed out by Jonathan Israel, the 17th Century Dutch Republic was more religiously tolerant than other European countries of the time, but its dominant Calvinist Church drew the line at groups who denied the Trinity; this was considered an intolerable aberration, and such groups were subject to various forms of persecution in the Netherlands. Other religions' views Judaism Some Kabbalist writings have a Trinitarian-esque view of God, speaking of "stages of God's being, aspects of the divine personality", with God being "three hidden lights, which constitute one essence and one root". Some Jewish philosophers additionally saw God as a "thinker, thinking and thought", taking from Augustinian analogies. The Zohar additionally says that "God is they, and they are it". Philo the Jew recognized a threefold character of God, but had many
