Summary
This article by Linda Thayer examines how the Council of Constantinople and subsequent theological developments solidified Trinitarian doctrine. It contrasts these historical developments with the Islamic doctrine of tawḥīd, arguing that Islam preserves the original monotheistic message preached by the prophets.
And do not say: Three [gods in a Trinity]! Desist! It is better for you. Indeed, God is but One God. Highly exalted is He above having a son! …Never shall the Messiah disdain to be a servant of God. [Surat Al-Nisa’, 4: 171-172]
Truly they have disbelieved who say that God is the third of three [in a trinity], while there is no other god but the One God. … The Messiah, son of Mary, was only a [mortal] messenger. … And his mother [too] was a [mortal] woman of [faith and] truth. … Say [to them]: Do you worship apart from God what holds neither harm nor benefit for you, while God is He who is the All-Hearing, the All-Knowing? … Do not exceed the bounds [of Heavenly faith] in the creed of’ your religion without [revealed] truth. And do not follow the whims of a people who have gone astray before [you.] For they have led many astray, having strayed from the even path [themselves]. [Surat Al-Ma’idah, 5:73-77]
In some measure the Arian stance was developed as a corrective to a skewed monotheism on the part of those who claimed to follow the monotheistic Jesus. While some might view Arianism as recognizing Jesus, in effect, as a prophet in all but terminology, we have been clear that Arians gave no evidence that they could think of rejecting Paul. [xvii] And the ‘deity’ of Jesus? Yes, Arians accepted this ‘divine’ – ‘divinity’ terminology in their allegiance to the innovative teachings of Paul, but—to their credit—they dragged their feet on defaulting to pagan concepts for understanding Jesus’ relationship to God. Having left behind Jesus’ Aramaic language [xviii] context—wherein the original ‘Father’-‘Son’ relationship was a coded messianic metaphor (see Part 8)—the Church blindly followed Paul into the Greek and Latin language arena of literal conceptualizations of these terms, and has remained therein until today.Monotheism In Interfaith Exchange – 8 | Linda ThayerConcludes Rubenstein: Arianism in its original form disappeared rapidly as a living force within the Roman Empire, and by the seventh century the last of the Arian tribes in Western Europe had been converted to Catholicism. (p. 227) Soon, most of the Eastern world would come under the domination of a new religion offering another interpretation of Jesus’ nature and mission. The Islamic Jesus was not the incarnate God of Nicene Christianity or the superangelic Son of the Arians. In the view of the Muslim conquerors, he was a divinely inspired man: a spiritual genius ranking with the greatest prophets, Moses and Muhammad himself. Apparently, this teaching struck a chord among large numbers of easterners who still thought of God as unitary, and who had not fully accepted Jesus’ incorporation into the Godhead. This may explain why, in the Middle East and North Africa, the whole [Christian] structure was swept away in a few decades by the Arab tribes and their clear Moslem doctrine of One God. With the ascension of Islam, Arianism as a discrete religious philosophy disappeared in the East as well as in the West. (Rubenstein, pp. 230-231) Yet, in fact, Arianism [xix] would never completely die among Christians: About one thousand years later, Arian beliefs would be espoused by a number of well-known English Protestants, some of whom would go on to create Unitarianism. (p. 227) Unitarian Christians Today Today the Unitarian Church/ Unitarian Universalist Society [xx] is a widespread, socially active movement—dating back to the mid-sixteenth century in Protestant [Christian] Europe—with religious services and discussion groups appealing to people from a variety of Christian, even Jewish and other, backgrounds. Unitarians are linked historically to an anti-Trinitarian belief system in which Jesus is seen as a prophet; they reject other mainline Christian beliefs like “original sin,” [xxi] “predestination” (predetermination) [xxii] and biblical “inerrancy.” [xxiii] They appreciate hearing diverse viewpoints and welcome Muslim speakers. Unfortunately, not many serious persons of Christian heritage are familiar with this option within Christianity, nor are they aware of the option of pure monotheism (Islam!) Thus most disaffected Christians choose—from among a narrowed set of options—to leave behind organized religion altogether or to consider something more contemplative or rationally spiritual. Arian Christians –> Muslims As we know, when the Muslim political conquest swept across North Africa, Mesopotamia and Asia Minor, Islam came to be readily accepted by Christian populations that had been Arian in their orientation to Jesus. Centuries later, in Medieval Christian Europe, the effects of Islamic conquest were still being felt culturally and academically: Arabic was a predominant language of scholarship, with ties to Andalusian Muslim Spain. [xxiv] All of this is beyond the scope of the topic at hand, although potentially of great historical interest in our interactions with our interfaith partners.
