To posit that another religion understands a less perfect version of the truth, or that the Gods of that religion do not truely exist is to be expected. However to claim that the Gods of all other religions are demons and fallen angels from your own religion is offensive.
I also think your confusing a lot of differant ideas from differant religions. Here is some interesting reading:
http://www.theosophy-nw.org/theosnw/world/christ/xt-ibel2.htm
Are you saying that Adam Weishaupt, Albert Pike, Helena Petrovna Blavatksy were luciferians? What do you base this on? My impression is that Gnostics tend to focus on Jesus and Sophia, I've done a little reading on the subject but found it annoying. Why would someone who believes something else, bother to pretend to be another religion? It would be so much easier to simply pretend to believe nothing, if they wanted to keep it secret.
They justified thier thirst for power and control with the need to spread thier faith. In thier defense, it's a common error made by most religions at some point in time.
Pragmatism. You come accross a village that believes in say... the Goddess Brigid. Brigid isn't viewed as a Supreme Diety of any sort, but as someone who intercedes on thier behalf. The Catholic Church makes her a Saint, saying that if people pray to her she will pray to God on thier behalf. Thier teachings about Jesus and Redemption however are the focus, and what would have been a long and violent transition becomes smooth and easy.
The other things you quote are further examples of the quest for power and pragmatism. When the Church/Religion wields temporal power it becomes corrupt. I'm not a Catholic and have never been a Catholic, however despite it's mistakes they have done a lot of good as well. They have also given up much of thier temporal power, so they are probably a lot less comprimised than the Church of old.
I think your confusing Paganism with temporal power. People in power saw that coopting religion would serve thier interests, religion felt that an alliance with temporal power would further it's own goals... so an alliance was made.
I suppose reading the Bible would insult you then.
Romans ch. 1
21: Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.
22: Professing themselves to be wise, they became fools,
23: And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
1 Corinthians 10:20 But I say, that the things which the Gentiles sacrifice, they sacrifice to devils, and not to God: and I would not that ye should have fellowship with devils.
To the Gnostics, the Demiurge/Devil is connected with the God of the Old Testament. This clearly runs contrary to the teachings of Yahshua/Jesus. As for evidence of Luciferianism.
"The Masonic religion should be, by all of us initiates of the high degrees, maintained in the purity of the Luciferian doctrine."
On July 14, 1889 Albert Pike issued instructions to the twenty-three Supreme Councils that gave a full exposition of his doctrines and beliefs. Pike stated:
"That which we must say to the crowd is - We worship a God, but it is the God that one adores without superstition.
To you Sovereign Grand Inspectors General, we say this, that you may repeat it to the Brethren of the 32nd, 31st and 30th degrees - The Masonic religion should be, by all of us initiates of the high degrees, maintained in the purity of the Luciferian doctrine....Yes, Lucifer is God, and unfortunately Adonay is also God." (Occult Theocrasy, p.220-221), [Edith Starr Miller]
from
Immorals and Dogma
Albert Pike was a lawyer, Confederate general, and 33rd degree Mason who wrote a book called Morals and Dogma, possibly the most important and influential of all Freemasonic works. There is a temple dedicated to him in Washington D.C.. It is called the House of the Temple and was modeled after the Mausoleum of Mausollos. Pike is also the only Confederate general who has a statue honoring him in D.C.. Other interesting historical personages worthy of investigation are John Dee, Francis Bacon, Helena Petrovna Blavatsky, Alice Bailey, Manly P. Hall, Aliester Crowley, and Jack Parsons. Benjamin Franklin's alleged connection with England's Hellfire Club is also an intriguing subject.
"Masonry is a search after Light. That search leads us directly back, as you see, to the Kabalah." (Morals and Dogma, p.741)
WHAT IS THE KABALAH?
The Kabalah,a Jewish Occult book, is a "Jewish mystical tradition teaching Godhood to Man. Foundation of most post-Egyptian, Western magical systems." (The Magicians Dictionary, p.208, [E.E. Rehmus, 1990 Feral House]
THE KABALAH SAYS THAT GOD IS AN "OCCULT LIGHT"
"To conceive of God as an actuality, and not as a mere nonsubstance or name, which involved non-existence, the Kabala, like the Egyptians, imagined Him to be 'a most occult Light,'"..(Morals and Dogma, p.740)
LUCIFER SUPPLIES THE LIGHT OF FREEMASONRY
"Lucifer, the Light-bearer! Strange and mysterious name to give to the Spirit of Darkness! Lucifer, the Son of the Morning! Is it he who bears the Light, and with its splendors intolerable blinds feeble, sensual, or selfish Souls? Doubt it not!" (Morals and Dogma, p.321)
Also from Immorals and Dogma linked to above.

Review one of my earlier posts to find a link about Theosophy.
Helena Petrovna Blavatsky wrote The Secret Doctrine Vol. I & II and was one of Theosophy's founders.
"We are about to found a magazine of our own, Lucifer. Dont allow yourself to be frightened: it is not the devil, into which the Catholics have falsified the name of the Morning Star, sacred to all the ancient world, of the bringer of light, Phosphoros, as the Romans often called the Mother of God and Christ. And in St. Johns Revelation does it not say, I, Jesus, the morning star? I wish people would take this to mind, at least. It is possible that the rebellious angel was called Lucifer before his fall, but after his transformation he must not be called so...."

Originally Lucifer Trust
http://www.lucistrust.org/
Alice Ann Bailey, a leading disciple of the Russian theosophist Madame Helena Blavatsky, formed the Lucifer Publising Company in 1920. 1922 saw the organization's name changed to Lucis Trust though the advancement of the Luciferian beliefs remained true. Beliefs that in Blavatsky's words: oppose the materialism of science and every dogmatic theology, especially the Christian, which the Chiefs of the Society regard as particularly pernicious.

As for Luciferians posing as Christians, I've been informed by the word of God that this is their modus operandi.
2 Corinthians
13: For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ.
14: And no marvel; for Satan himself is transformed into an angel of light.
15:Therefore it is no great thing if his ministers also be transformed asthe ministers of righteousness; whose end shall be according to theirworks.
Matthew 7:15 Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.
Acts chapter 20
28: Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood.
29: For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.
30: Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them.
31: Therefore watch, and remember, that by the space of three years I ceased not to warn every one night and day with tears.
Sometimes they pretend to be atheists sure. The reason you find all this impractical is that you don't believe they are led, dominated, and even possessed by supernatural beings of astronomical intelligence and millenia of experience who are deceptive by their very nature.
John 8:44: Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him.
When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
9: And the great dragon was cast out, that old serpent, called the Devil, and Satan,
which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
2 Thessalonians chapter 2
9: Even him, whose coming is after the working of Satan with all power and signs and
lying wonders,
10: And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
The reason they pose as Christians is because they want to destroy Christianity. The best way to destroy anything is from within.
You really don't see any evidence of sun worship or paganism in the Catholic church? Okay.
