An Agnostic's Look at The Bible - Part XI (Those Pesky Heretics)

This particular post will be less about what's in The Bible and more about how third and fourth century (and later) theologians attempted to reconcile the inconsistencies and contradictions about Jesus' nature in The Bible. 

By the Second Century it was already established among the vast majority of Christians that Jesus was God. But in what sense was he God? That's where the debates and the branding of other theologians as heretics comes in. The Gospels also make very clear that Jesus was a man, but in what sense was he human? How did his humanity and divinity coexist in one person? Was he half God and half man? Was he God who just appeared to be a man? Was he a man who was "promoted" to Godhood? I want to make clear that the Gospels and Epistles do not make any of this clear. And the answers that eventually led to the doctrine of The Trinity were by no means self-evident. Assumptions made by theologians were just as often based on what they thought was common sense or to avoid infelicitous outcomes. Here are a few of the possible "solutions" to the nature of Jesus that eventually were deemed heresies:

• Adoptionism stated that Jesus did not pre-exist before his birth but was "adopted" as the Son of God at his Baptism (or resurrection, or Ascension)  due to his perfect, sinless life. His reward was resurrection and adoption into "the Godhead". This was put to rest around 200CE, but it seems to me that it has solid scriptural basis. 
• Docetism adherents believed that Jesus only appeared to have a physical human form. They believed that matter was inherently evil and therefore God couldn't have had a physical body. 
• Apollinarianism stated that, although Jesus had a physical, human body, his "nature", or mind, was wholly divine.
• Arianism has been latched onto by modern day non-Trinitarians to support their belief that the early Christians were not Trinitarians. Arius didn't teach that Jesus was not God, but that Jesus, God the Son, was created first by God the Father and that the rest of the universe was then created by the Son. The main difference between Arianism and the version of Trinitarianism that the majority of theologians were adhering to was that the Trinitarians believed that the Son and the Father were "co-eternal", i.e. there was never a time when the Son did not exist, while the Arians taught that the Father pre-existed the Son. This dispute was what spurred the Council of Nicaea. Arians for hundreds of years constituted the majority of Christians outside of Rome and Byzantium. It effectively died out when Charlemagne accepted Catholic Christianity. 
• Nestorianism was a branch of early Christianity wherein their founder Nestorius taught that Mary gave birth only to Jesus' human nature. They argued about the term "Mother of God", preferring the title "Mother of Christ".  Nestorius' followers fled persecution relocating to the Persian Empire where they further developed the idea that Jesus, although one person, had both a human and a divine nature.  Nestorians flourished under the Persians and Nestorian churches continued to exist even after the Muslim conquest of Persia. 
• Monophysites believed that Jesus had only one nature - that his humanity was absorbed by his divine nature. They were the majority in the border regions of the Eastern Roman Empire and had competing bishops and patriarchs when the Crusaders conquered Jerusalem and the surrounding area. 
• Monothelitism was a response to Monophysitism, holding that Jesus had two natures, human and divine, but one "will" - divine. 
• Sabellianism teaches that the Father, Son and Holy Spirit are one and the same, but are different modes or expressions of a unitary God.

Eventually the doctrine of The Trinity emerged with earlier understandings later being branded as heretical. In it Jesus is described as fully God and fully human as regards both his nature and his will, not half God/half human, not a human who was "promoted" to God. As "God the Son" he existed for as long as God the Father existed and was somehow begotten while having always been begotten. The three "persons" of The Trinity are all equally God, yet distinct. It's complicated, and I doubt that many Christians understand the explanations that their theologians came up with. 

Non-Christians and non-Trinitarian Christians sometimes mock the belief, wondering who Jesus was talking to when he prayed to God, among other things. But do any supernatural religious beliefs make any sense?
