Well the evidence from Deuteronomy and Ezekiel is quite explicit, and I can see why the Hebrew peoples would have had specific directives to be careful of worshipping the Sun. They were surrounded by Sun worshipping cultures.
But I wonder how many new Christians knew of these biblical passages. Christianity did develop out of a culture known for its lack of religious imagery generally, and yet chose to use certain very mundane symbols. Perhaps it is the very mundain nature of a fish and a cross that was important. Solar imagery of the time would have been epic and monolithic.
Interestingly, if you look at Christian imagery, especially Gnostic and Orthodox, there some solar-like items. Particularly the halos and glowing balls of light that surround saints' heads. These soughts of things were adopted after the Bible's contents would have become somewhat more widespread. Or perhaps it just takes advantage of the whole "light is holy and good" angle.
That's an excellent point.
The cultures that surrounded Hebrew people were sun worshipers but an interesting difference is that the cultures didn't view the sun (only) as light; the sun was viewed as fire. Many of those cultures (e.g. the Zoroastrians) either worshiped fire or held fire to be in high esteem.
Christian imagery did not follow suit; fire represented Hell (evil). The Gospels even delineate between the imagery of fire and the imagery of light:
Matthew 16:40-43; English Standard Version
40 Just as the weeds are gathered and
burned with fire, so will it be at the close of the age. 41 The Son of Man will send his angels, and they will gather out of his kingdom all causes of sin and all law-breakers, 42 and
throw them into the fiery furnace. In that place there will be weeping and gnashing of teeth. 43 Then
the righteous will shine like the sun in the kingdom of their Father. He who has ears, let him hear.
Other lines from the New Testament emphasize that the path of Hell/evil is fire/fiery.
Matthew 25:40-43; English Standard Version
40 And the King will answer them, ‘Truly, I say to you, as you did it to one of the least of these my brothers, you did it to me.’ 41 “Then he will say to those on his left,
‘Depart from me, you cursed, into the eternal fire prepared for the devil and his angels.42 For I was hungry and you gave me no food, I was thirsty and you gave me no drink, 43 I was a stranger and you did not welcome me, naked and you did not clothe me, sick and in prison and you did not visit me.’
Luke 16:23-24; English Standard Version
23 and
in Hades, being in torment, he lifted up his eyes and saw Abraham far off and Lazarus at his side. 24 And he called out, ‘Father Abraham, have mercy on me, and send Lazarus to dip the end of his finger in water and cool my tongue, for
I am in anguish in this flame.
2 Thessalonians 1:5-8; English Standard Version
5 This is evidence of the righteous judgment of God, that you may be considered worthy of the kingdom of God, for which you are also suffering— 6 since indeed God considers it just to repay with affliction those who afflict you, 7 and to grant relief to you who are afflicted as well as to us, when the
Lord Jesus is revealed from heaven with his mighty angels 8
in flaming fire, inflicting vengeance on those who do not know God and on those who do not obey the gospel of our Lord Jesus.
