OK Terry, sounds convincing, until you start to think a little deeper. I think you'll appreciate that "ALL" religious thought can be based on previous thinking and myths. In that sense, All religion can be based on "stolen ideas.'
But first:
1. Christianity (as distinct from Judaism) is rooted in the Greek language, all the terms you discussed are English terms translating the original Greek terms. To do what you do in your original post, is biased away from possible understandings of the original Greek.
But the original Greek had to translate the Hebrew concepts. In translation, too often there are no words that convey the precise meaning of the word you wish to translate.
But moving on to my main point:
2. It would be quite easy to construct an argument that the gentile converts stole the original Jewish Christianity and replaced it with a new construct based on Plato's thinking. All educated people that converted to the new Christian concept, were educated in Graeco-Roman thought. They attempted to discuss their religious ideas with words and concepts that made sense to them,
3. But we can go back further than that. What was the original Jewish (Israelite) religion like? Again, it would be easy to construct an argument that the original (native) Hebrew concepts were based first on Egyptian thought. Why? Because for some hundreds of years, Egyptian armies occupied the land of Israel. The creation story in Genesis 1 is quite similar to Egyptian creation stories. After the Egyptians, came Semitic influence, also affecting Hebrew thought as evident in the concept of a global flood. To save writing time, I'll post part of a Wikipedia entry on 'Global Flood:'
" Mythologies: The Mesopotamian flood stories concern the epics of Ziusudra, Gilgamesh, and Atrahasis. In the Sumerian King List, it relies on the flood motif to divide its history into preflood (antediluvian) and postflood periods. The preflood kings had enormous lifespans, whereas postflood lifespans were much reduced. The Sumerian flood myth found in the Deluge tablet was the epic of Ziusudra, who heard the Divine Counsel plan to destroy humanity, in response to which he constructed a vessel that delivered him from great waters.[2] In the Atrahasis version, the flood is a river flood.[3]
In the Genesis mythology of the Hebrew Bible, Yahweh (God) decides to flood the earth because of the depth of the sinful state of mankind. Righteous Noah is given instructions to build an ark. When the ark is completed, Noah, his family, and representatives of all the animals of the earth are called upon to enter the ark. When the destructive flood begins, all life outside of the ark perishes. After the waters recede, all those aboard the ark disembark and have God's promise that he will never judge the earth with a flood again. He gives the rainbow as the sign of this promise.[4]
In the 19th century, Assyriologist George Smith translated the Babylonian account of a great flood. Further discoveries produced several versions of the Mesopotamian flood myth, with the account closest to that in Genesis found in a 700 BCE Babylonian copy of the Epic of Gilgamesh.[5]:20 In this work, the hero Gilgamesh meets the immortal man Utnapishtim, and the latter describes how the god Ea instructed him to build a huge vessel in anticipation of a deity-created flood that would destroy the world. The vessel would save Utnapishtim, his family, his friends, and the animals.[6]
In Hindu mythology, texts such as the Satapatha Brahmana and the Puranas contain the story of a great flood,[7] wherein the Matsya Avatar of Vishnu warns the first man, Manu, of the impending flood, and also advises him to build a giant boat.[8][9][10]
In Plato's Timaeus, Timaeus says that because the Bronze race of Humans had been making wars constantly Zeus was angered and decided to punish humanity by a flood. Prometheus the Titan knew of this and told the secret to Deucalion, advising him to build an ark in order to be saved. After 9 nights and days, the water started receding and the ark was landed at Mount Parnassus.[11]"
Its easy to see how the flood story spread into other cultures as organised groups of humans developed their own myths based on the original myth.
When (eventually) the Jewish people were exposed to new religious thinking (during the Babylonian captivity) the most influential religion was Zoroastrianism. The result was the infiltration of 'dualism" into Jewish thought.
Sometimes, (it can be speculated) original Jewish writings were redacted to fit their new understandings. And, that is how we got to the point where what you call 'mainstream Christianity" could call orthodoxy. Even so, we can still find differences, between the main streams of Christian thought.
Actually, in my JW experience, most of the distinctions that the witnesses have made, already had some prior group who also differentiated themselves from the mainstream,
Footnote:
Maybe I should post some thoughts on Platonism, from key Christian thinkers after the first century.
1. Augustine:
“The utterance of Plato, the most pure and bright in all philosophy, scattering the clouds of error . . .”
“I found that whatever truth I had read [in the Platonists] was [in the writings of Paul] combined with the exaltation of thy grace.”
2. Eusebius of Caesarea:
“[Plato is] the only Greek who has attained the porch of (Christian) truth.”
3. Clement of Alexandria, (not the Clement who was the first Pope of late first century):
“. . . before the advent of the Lord, philosophy was necessary to the Greeks for righteousness. And now it becomes conducive to piety; being a kind of preparatory training to those who attain to faith . . . . For God is the cause of all good things, but of some primarily, as of the Old and New Testaments; and of others by consequence, as philosophy. Perchance, too, philosophy was given to the Greeks directly and primarily . . . . For [philosophy] was a schoolmaster to bring ‘the Hellenic mind . . . to Christ.’ Philosophy, therefore, was a preparation, paving the way for him who is perfected in Christ.”
