1.  The sun 'dies' on the 22nd of december, the winter solstice, when it stops it's movement south, to be born again three days later on 25th december when it resumes it's movement northwards.  This period was originally in the star sign of VIRGO, hence the....born of a VIRGIN.

First of all, the sun doesn't move.  The Earth does.  Okay, so clearly the critic here is referring to the movement of the sun IN RELATION to the Earth.  In that case, it never stops moving because the Earth never stops moving.  There is no three-day period when the sun's movement in relation to the earth stops altogether.  It may appear to slow for those three days, but since the slowing of the movement is a gradual thing, one could argue that it 'stops' for the one, two, four, five, or six days around the winter solstice as well (it depends on how slow you consider 'stopping').  And besides all of that, Jesus' resurrection happened in the spring, not in December.  As for the period being 'originally in the sign of Virgo', Virgo is from August 23rd to September 22nd.  I've never heard of the winter solstice happening in the fall.

2.  The sun is the light of the world, cometh on clouds and every eye shall see him, wears a corona-crown of thorns and "walks on water" when it sets.

Yes, it's the light of the world, but clearly not in the same sense that Jesus is.  It doesn't 'cometh on clouds', but is far above the clouds.  Every eye (at least the non-blind ones) DO see the sun, not SHALL.  There are no thorns on the sun, and it doesn't walk on water.  Is the critic arguing that if you're standing on the shore watching the sun set over the ocean, it appears to walk on water?  Well, what if you're watching it set over a desert, or a city, or a mountain?  Does the sun also walk on deserts, cities, and mountains?

3.  The sun's 'followers' or 'disciples' are the 12 signs of the zodiac, through which the sun must pass.

How does the critic suppose that the zodiacal signs 'follow' the sun?  Yes, the sun passes through the signs.  Did Jesus 'pass through' his disciples?  All they're showing is a similarity of the number 12.  So anywhere we see twelve of something, it's based on the zodiac?  When I buy a dozen eggs, those eggs are representative of the twelve signs of the zodiac?

UPDATE: AnsweringInfidels.com makes another good point.  The 12 apostles were almost certainly assigned because of the 12 tribes of Judah.  Skeptics might say that 12 tribes of Judah were based on the zodiac, but the division of the twelve signs of the zodiac didn't occur until the 5th century B.C., well after the time of the 12 tribes.

4.  The sun enters each zodiac sign at an angle of 30 degrees- hence the SUN of GOD begins his ministry at the age of 30.

Again, this is just a similarity of the number 30.  Very weak.  How does a degree equal a year?  Does it take a year for the sun to move a single degree?  Of course not.  Also, this is a minor point, but the Bible says Jesus was 'about thirty', and historians place his age at closer to 33 or 34 when He began His ministry.  As for sun/son, again, this homonym is in the English language only.

5.  The sun passes through the vernal equinox at easter at which time the sun is resurrected.

I wasn't aware that the sun died, or that people thought it did.  The author of this list is taking words associated with Christianity and using them to create non-existent comparisons.  All we really have is that the sun passes through the vernal equinox at Easter.  Is Jesus supposed to have passed through the vernal equinox at Easter?  Does anything which passes through the vernal equinox at Easter die and get resurrected?  Besides that, Easter never falls on the vernal equinox, but is always later (sometimes over a month later).

6.  The sun at its zenith, or 12 noon, is in the house or heavenly temple of the 'Most High'; thus, 'he' begins 'his Father's work' at 'age' 12.

First of all, the Hebrews counted hours from dawn, not from midnight as we do, making the sun's zenith roughly the sixth hour of the day, not the twelfth.  Secondly, how does the critic here figure that the sun begins its work at noon?  Doesn't it begin its work at dawn?  It rises at dawn (roughly 6:00), so shouldn't we more accurately say that the sun begins its work at six, or zero?

7.  The sun is the 'Lion' when in Leo, the hottest time of the year, called the 'throne of the Lord.'

I'm not clear whether the critic here is saying that Leo is the 'throne of the Lord', or that the hottest time of the year is the 'throne of the Lord'.  Whichever it is, who calls it that?  This one appears to be further nonsense.

8.  The sun is 'betrayed' by the constellation of the Scorpion, the backbiter, the time of the year when the solar hero loses his strength.

How does the sun lose its strength?  Perhaps they mean that it's not quite as powerful in the northern hemisphere at this time (though, since its becoming more powerful in the southern hemisphere, this is an offset).  Also, Scorpio is from October 23rd to November 21st.  Yes, it becomes less powerful in the Northern hemisphere during this time, but it also becomes less powerful during the constellations preceding it and the one following it, so why is Scorpio being singled out here?  And what does the scorpion have to do with backbiting?  Yes, they occasionally bite people, but is there a significance to the back associated with them somehow?  Why not the 'footbiter' or the 'handbiter'?  I'm sure the outer extremities get bitten more often than the back.

9.  The sun is hung on a cross, which represents its pasing through the equinoxes, the vernal equinox being Easter.

This one is just nonsense.  As it passes through the equinoxes, it's moving in a straight line north-to-south or south-to-north.  How does a straight line make a cross?  What is the east-west line that the critics are imagining here?

10.  The sun does a 'stutter-step' at the winter solstice, unsure whether to return to life or 'resurrect,' doubted by this 'twin' Thomas.

Since the sun always heads back north at the winter solstice, how is it unsure of whether to 'return to life'?  That sounds pretty certain to me.  And how does its northward progression represent a 'return to life'?  Is its southward progression a 'return to death', then?  And what is the sun's twin in this metaphor?

For that matter, is there anything in the Bible suggesting that Jesus was unsure of whether to return to life?  And how did Thomas figure into this?  Thomas doubted, after the fact, that Jesus had returned to life.  Even if, hypothetically, Jesus had a choice to make as to whether to return to life, Thomas had no bearing on that decision.  And how is Thomas Jesus' twin?

In question five, they claim the sun's 'resurrection' happens in the spring solstice, and now they're claiming it happens in the winter solstice.  Is the sun 'resurrected' at every solstice, then?  Of course, in 'parallel' 15 (below) they say its rebirth happens every month!  Methinks the critics are a tad confused.

11. The sun of god is 'born of a virgin,' which refers to both the new or 'virgin' moon and the constellation of Virgo.

How is the sun born of a new moon?  Virgo is from August 23rd to September 22nd.  How is the sun 'born' during this period?

12.  The sun is the 'Carpenter' who builds his daily 'houses' or 12 two-hour divisions.

So is the critic claiming that the 24 hours of a day are created by the sun each day?  Not that I'm aware of.  And where does the '12 two-hour divisions' come into this?  Why not three eight-hour divisions or four six-hour divisions?  Is this supposed to be a reference to the zodiac?  So are the zodiacal signs created daily?  More nonsense.

13.  The sun is 'anointed' when its rays dip into the sea.

According to whom?

14.  The sun 'changes water into wine' by creating rain, ripening the grape on the vine and fermenting the grape juice.

Well, it does ripen the grape on the vine.  But it doesn't create rain or ferment the grape juice (most fermentation takes place indoors).

15.  When the sun is annually and monthly re-born, he brings life to the 'solar mummy,' his previous self, raising it from the dead.

I'd really like to know who declares the sun re-born either annually or monthly.  And besides, when was Jesus reborn?  His followers are reborn in the spiritual sense, but Jesus Himself had only one birth.  Even if we're going to accept Jesus' resurrection as a 'rebirth' (though it clearly wasn't), His resurrection happened only once, not annually or monthly.  And there are no mummies in the Jesus story.

16a.  The sun is 'crucified' between the two thieves of Sagittarius and Capricorn.

Let's see...Sagittarius is from November 23rd to December 21st, and Capricorn is from December 22nd to January 19th.  So, does the critic here think that Jesus was crucified in December?  Does he think the sun is crucified in December?  According to whom?  How so?  And how are Sagittarius (an archer) and Capricorn (a goat) thieves?

16b.  According to legend, Jesus was born in a stable between a horse and a goat, symbols of Sagittarius and Capricorn.

According to what legend?  There's no reference to a horse and a goat in any story I've heard.  And since when is a horse the symbol of Sagittarius?  The archer is the symbol of Sagittarius.

16c. Jesus was crucified at the winter solstice between the 'two thieves' of Sagittarius and Capricorn, who sapped his strength.

Jesus was crucified around the spring solstice, not the winter solstice.  And how did the two thieves sap his strength?  And, again, how are Sagittarius and Capricorn thieves?

(note: I made these three parallels 'a' 'b' and 'c' because they're similar, but never on the same list.)

17.  The sun is the Word or Logos of God.

Once again, according to whom?

18.  He was baptized in Aquarius, the Water-Bearer.

Aquarius is January 20th to February 18th.  Who says Jesus was baptized at this time?  Or is the critic claiming that since Jesus was baptized in water, this must correspond somehow to the constellation of Aquarius.  Every time I take a shower, does this correspond to the constellation of Aquarius?  Weak, weak, weak.

19.  Jesus became the Good Shepherd and the Lamb in Aries, the Ram

Huh?  How do a 'Good Shepherd' and a 'lamb' correspond to Aries, the Ram?  Are they saying it happened at that time of year?  So what?

20.  Jesus told the parables of the sowing and tilling of the fields in Taurus, the Bull.

Once again, what the heck are the critics talking about here?  Are they claiming that the parable was told during the April/May period identified with Taurus?  If so, so what?  My birthday's in this period, so does this make my life a myth?

21.  In Cancer, 'the celestial Sea of Galilee,' he calmed the storm and waters, spoke of backsliders (the Crab), and rode the ass and foal in triumph into the City of Peace, Jerusalem.

How is Cancer 'the celestial Sea of Galilee'?  No one's ever called it that.  So what is the critic's point here?  That the calming of the storms, and His riding into Jerusalem happened in the June/July period identified with Cancer?  Unlikely, but even if it was...so what?  And how is the backslider represented by the crab?

22. In Libra, Christ was the true vine in the Garden of Gethsemane, the 'wine press,' as this is the time of the grape harvest.

Once again...so?  What does Libra (the scales) have to do with any of those events?  Why is the 'wine press' in quotes?  Is wine supposed to be pressed between scales or something?

23.  In Sagittarius, Jesus was wounded in the side by the Centaur, or centurion.

How are Centaurs (half man/half horse creatures) supposed to correspond to centurions (which were fully man)?  Does the critic expect us to believe that, since those words sound alike (at least in English), centaurs and centurions are interchangable?  This one is an insult to any rational person's intelligence.  Also, Sagittarius (an archer, having nothing to do with centaurs or centurians) is in November and December, several months removed from Jesus' crucifixion.
