One god, two gods, three gods... What difference does it make?
Incredible difference. Read Plato. One God is much more reasonable than more than one. Any monotheistic religion instantly gets more 'reasonability points' than a polytheistic religion.
You have reaffirmed your belief that monotheism is more reasonable than polytheism, and you have cited a Greek philosopher who advanced that position. (And monotheism was not a new idea in Plato's time. It went back at least to ancient Egypt.) Can you explain to me why YOU think monotheism is more "reasonable" than polytheism? After all, Christians believe in all sorts of spiritual beings--angels, demons, saints. Many Christians even pray to saints and angels. That certainly isn't much different from having lesser gods in a pantheon. I see no significant difference except in what you choose to call a "god".
Indeed, the Hebrews believed in the existence of other gods until roughly the 6th or 7th centuries BC...
An unsubstantiated claim, and further, totally irrelevant. Distant history of what one group may or may not have believed has little relevance to the truth or falsity of the claims i am making about the validity of Christian/hebrew revelation. Peoples' beliefs do not dictate what is true or not.
This claim has been substantiated for those who care to look at the evidence. See, for example, Gordon and Rendsburg's classic historical work
The Bible and the Ancient Near East. And how can you dismiss this as irrelevant to a discussion? We were discussing a point that you yourself injected into the discussion: "because it is upheld by a consistent tradition of revelation carried over thousands of years and between many different authors." Evidently, that tradition was not so consistent.
I know of others with even longer traditions...
All of those are polytheistic, thus failing my point a, and thus irrelevant.
Revelation is revelation, whether one god or twenty gods are involved. You've not proven your point, and you seem even to have recognized the irrelevance of your point b.
Monotheism and consistent, diverse authorship. No other religion that i know of can claim those.
Inconsistent, diverse authorship, as I've already pointed out. And the Hebrews were not the only group in the Achaemanian Empire to move towards monotheism. Even Marduk was touted as the supreme "good god" for a period of time. Zoroastrian dualism, yet another competing chain of "revelation", was the catalyst that eventually turned subject nations in their empire towards evangelical monotheism.
Also, of interesting note, many of the disciples/apostles of Christ were killed for claiming to have seen him risen from the dead. Would you follow something you knew to be untrue to the death? Neither would they. The only reason they persisted to the death was because they knew the truth. This is further evidence for the validity of Christian revelation- God revealing himself in the form of a man named Jesus. Show me another religion where men went to death for something that concrete- having said they saw a man come back to life.
Is it your position that the 9/11 suicide-terrorists "knew the truth"? Do you believe that WWII Japanese kamikaze pilots destroyed themselves because they knew that Hirohito was a god? History is full of fanatics who have been willing to die for false religious beliefs. Your argument doesn't make sense.
1. Muslims have been known to go to death for a private revelation. Sorry, but private revelation is much poorer than corporate revelation.
How so? In any case, Christianity is based on private revelation as much as the other religions.
2. Hindus have many authors to their scriptures. Sorry, but they believe in many competing gods, and that is much less logical than a single God.
Nonsense. Hindu scripture differs not at all from the Hebrew tradition in terms of its history of different authors contributing critiques and redactions. If anything, the Hindus had devised far more elaborate means of transmitting their scripture in both oral and written traditions.
3. Buddhists... mostly don't believe in any God /gods.
False. Buddhists mostly don't worship gods. Most Buddhists believe in gods and spirits.
4. Most ancient religions are incredibly polytheistic, and the greek and roman pantheon in particular was very competitive. Sorry, but that's totally illogical. Cool stories, but metaphysically irrational.
Actually, the belief that there was one supergod behind all the others was quite common in ancient times. It was a natural step to demote the demigods to saints and angels. Christian traditions rest solidly on the pagan ones that came before.
Now actually to get back to your point of the Hebrews believing there were many gods but one to be praised above all others. That is not so far off. There are many competing spirits in this world. Some call them angels or demons, or other names. You may dismiss this idea out of hand, but it is true. But there is only one God-with-a-capital-G, only one right, and effectively the other gods pale in comparison and really disappear when compared to the One God. So if this is what you meant about the Hebrews past, then such a belief is true. I don't know if they really believed it, but that's not so far off.
The Yahwist tradition was monolatrous. The believed in other gods but worshipped Yahwe to the exclusion of those others. Under Egyptian and Persian influence, they came to see Yahwe as the only god. The Devil was modeled on the Persian concept of Ahriman, who was ther evil alternative to their good god, Ahura Mazda. Basically, the Hebrews stopped treating their version of Ahriman as a god that was on equal footing with the good god.
