I don't agree with the notion (If I have understood you correctly) that the 'orthodox' church is a 'false' church.
The professed Church of Christ at its inception and for the most part all throughout the Ephesus stage (the first stage of the Church) and the Smyrna (the second stage) was pure. While the Apostles were present and with the gift of discernment of spirits at their disposal they were able to insure no unsavory elements entered the fold, but not too soon after the last of these apostles died, this unsavory element began to grow, Satan having sown the seeds of the tare element in among the professed Church. The Apostle Paul warned of this when he stated, “After my departing grievous wolves shall enter in among you, not sparing the flock." (Acts 20:29, 30)
The professed church became overwhelmed by this unsavory element and not soon after (beginning in Pergamos stage: meaning “earthly elevation”) committed fornication with the world when it was joined to earthly governments. The professed or orthodox church (Babylon as the Lord calls it, the apostate church) is composed primarily of tares, nominal Christians, Christians in name only, begotten not of truth, but of error. These unfortunately being in the majority have since run all the various church organizations and as such have both dictated and taught what is to be considered acceptable teaching in the orthodox Churches.
Nor can I, I believe, get behind the notion that the Papacy is the Antichrist. Can I agree to the idea that some Popes have displayed antichrist-like spirit? Sure. As have many other 'leaders'. As John said, "there have been many"...but there will be more before the one.
That Papacy (the system, NOT individual Catholics) is THE Antichrist has been well establish and pointed out by all the great reformers. Papacy has fulfilled every declaration concerning the Antichrist which is written in the scriptures.
If you are not familiar with the claims of Papacy you cannot see how it exalts itself and opposes God. It claims that its representative the Pope is "King of Kings and Lord of
Lord's"--"The Prince of the Kings of the earth." As Christ's vicegerent he is the Pa-pa --Pope or Father of mankind, i.e., "The everlasting Father”, “The Prince of peace”, “The Mighty God" (or ruler).
All these and every other title announced by the prophets relative to The Christ in glory during the millennial reign, are considered proper and applicable to the Pope whom they claim to be Christ's vicar or instead of Christ.
Do the scriptures declare the reign of Christ over the nations for a thousand years, and that he must reign until he shall put all enemies under him?
Papacy claims that when exalted to power it did put down all enemies and that for a thousand years it did reign over the kingdoms of earth. (Generally dated I believe from A.D. 792 to 1792). They claim that the Millennial reign of Christ and his saints, Rev. 20, there took place and that the period since the overthrow of Papacy's dominion (1798 A.D.,) is the little season mentioned in verses 3,7 and 8 during which the "devil is loosed," i.e. Protestantism and all infidelity to Papacy.
During her reign over earth's king's she did "rule with a rod of iron," claiming that it was the fulfillment of Psa 2:6-12. [Read it.] Special emphasis was given to verses 10-12, "Be wise now therefore O ye kings....Kiss the Son lest he be angry, and ye perish from the way, when his wrath is kindled but a little."
To fulfill this, the kings of earth were obliged to kneel before the Pope and kiss his great toe to receive his blessing and their crowns. (On one occasion, to show the superiority of the Pope-- that he was indeed "King of Kings," the crown after being placed on the head of the prostrate king by the Pope's hand, was kicked off with his foot, then lifted between his feet and thus put on the king.) For centuries no king reigned in Europe without this appointment and blessing of the Popes. To offend was to forfeit their titles and thrones.
Thus, by claiming God's honors and worship, Papacy exalted itself and opposed God. To illustrate the claims of Papacy let me quote a few of its "great swelling words."
It was the boast of Gregory II that "all the kings of the west reverence the Pope as a God on earth." An oft accepted title was "Our Lord God the Pope." At the Lateran council, the Pope was addressed thus: "Thou art another God on earth."
Pope Martin said: "The greatness of Priesthood began in Melchisedec, was solemnized in Aaron, continued in the children of Aaron, perfectionated in Christ, represented in Peter, exalted in the universal jurisdiction and manifested in the Pope. So that through this pre-eminence of my priesthood--having all things subject to me, it may seem well verified in me, that was spoken of Christ, 'Thou hast subdued all things under his feet.'...I am all in all and above all, so that God himself and I the vicar of God have both one consistory [co-equal, or on the same footing.] ...Wherefore, if those things that I do be said not to be done of man but of God, WHAT CAN YOU MAKE OF ME BUT GOD? Again, if prelates of the church be called and counted of Constantine for Gods, I then being above all prelates seem by this reason to be ABOVE ALL GODS. Wherefore no marvel if it be in my power to change time and times, to alter and abrogate laws, to dispense with all things, yea with the precepts of Christ."
It is marvelous that anyone can doubt that the above was the blasphemous utterance of the Anti-Christ.” (R305)
Keep in mind that the various Popes themselves have merely served as the heads of this organization and are not to be considered THE Antichrist itself. The Antichrist is a system (of error) NOT an individual.
I will address your concerns about the significance of the sun and the moon in my next post.
