Lots of good points but I have lots of problems here with these explanations Isa:
1)We have the Temple scroll, there was a pre-specified plan for the temple, not a random pagan design. Absurd to say God would allow pagan contamination where he placed his presence.
This isn't a Masons' Treasure, is it? What "Temple scroll" are you talking about.
2)The Mandylion was MADE by God, it is the image of God, the presence of God shining on the clothe (Jewish concept of the Shekinah, like on Moses when he descended the mountain). So its OK. So Mar Mari and Addai can ask us to revere the Mandylion.
Go with that Apostolic thought.
3)I don't know if the story was in the talmud, plus even though much of the talmud is gunk, much of it is useful and contains legends and knowledge which the apostles drew on.
No, they didn't. Consult Council of Jerusalem.
We don't use the book of Enoch but Jude quoted it. Plus Moses was buried in secret because God did not want his tomb turned into a shrine full of iconography.
Well, that didn't work out.

What do you base you assertion on?
Btw, interesting that Satan wanted Moses' body. Why?
4) Samaritans used icons:

Interesting link. Underlines the problem:pre-Christian synagogues have n't survived.
Since you are going that late, not out of bounds would be these Jewish Synagogues:




don't be a samaritan 
Lent is coming, and I hope to be a Good one.
5) Good you remembered: God is not "incarnate" flesh, he does not have blood. Thus it is still forbidden to depict spirits with images. Worship the Father in spirit and in truth.
And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world. I John 4:3
For many deceivers have gone out into the world, those who do not acknowledge Jesus Christ as coming in the flesh. This is the deceiver and the antichrist. 2 John 1:7.
6) OK, as soon as I read the words "Icon" and "Demon" in the same story I became suspicious of demonic attempts at making people worship idols.
Why should that be suspicious? The demons are expert at citing Scripture.
I'm still suspicious, maybe the demon wanted to give the impression that it is ok to use icons. If he was worshipping a holy icon why was he demonically possessed with lustful thoughts?
II Corinthians 12:9.
7)No Jewish icon as of yet, only samaritan ones. The Samaritan Torah is very similar to the original except they switched Mount Zion to another mountain associated with Joseph and a couple other things.
The icons of Dura Europas are Jewish: there are scenes not from the Torah, and the Samaritans only accept the Torah (edited for Mount Gerezim).'
I haven't seen any Samaritan icons on this thread yet, except the one on your link. See the Jewish version above, similar in age.
