Let me give a reality check. You talk about the Bible. Well in it, Paul says that those who teach will receive a stricter judgment. And warns "let not many of you become teachers", for this reason.
I would not like to be in your shoes/sandals on judgement day for claiming that the majority of the world's Christians, literally hundreds of millions of believers, are worshipping the beast because they go to church on Sunday.
It is one thing to say that you believe the OT Sabbath still applies. It is a completely different thing to say in conclusion that all Sunday church going Christians are in league with Satan.
You need to repent of such vile beliefs. I remind you again of Paul's words: "Let not many of you become teachers". May God have mercy on you for proclaiming hundreds of millions of Christians as Satanic merely because of Sunday fellowship.
I can see by your Avatar page that you have spiritual discernment. But I'll share anyway because you never know what God will do.
Sun worship, in the Lord's house, has its root in Babylon.
Ezekiel 8:16 Then he brought me into the inner court of the Temple and there at the door, between the porch and the bronze altar, were about twenty-five men standing with their backs to the Temple of the Lord, facing east, worshiping the sun!
Sunday is the day sun worshipers honor it's called, "The Venerable Day of the Sun". http://en.wikipedia.org/wiki/Sol_Invictus
The Bible is very clear as to what the Beast is. It's a kingdom that began forming in Babylon and ended with Papal Rome.
The Beast in Revelation 13 decribes Papal Rome.
Papal Rome is the little horn kingdom that changed God's Law and time.
Papal Rome changed God's seventh day Sabbath from the seventh day (Saturday) to the first day (Sunday) as it relates to worship.
Official quote from The Catholic Catechism
Question - Which is the Sabbath day?
Answer - “Saturday is the Sabbath day.”
Question - “Why do we observe Sunday instead of Saturday?”
Answer – “We observe Sunday instead of Saturday because the Catholic Church, in the Council of Laodicea (A.D. 364), transferred the solemnity from Saturday to Sunday." Peter Geiermann,C.S.S.R., The Convert's Catechism of Catholic Doctrine, p. 50, 3rd edition, 1957.
What was established at the Council of Laodicea in 364-AD regarding the seventh day Sabbath of the fourth commandment?
Council of Laodicea (A.D. 364)
"Christians shall not Judaize and be idle on Saturday, the Sabbath, but shall work on that day; but the Lord's day (Sunday) they shall especially honor, and, as being Christians, shall, if possible, do no work on that day if however, they are found Judaizing, they shall be shut out from Christ.”---Canon 29, Council of Laodicea, 364 C.E.
Papal Rome has no problem admitting this change.
Official Statement of the Catholic Church
“Sunday is our mark of authority, the church is above the Bible, and this transference of Sabbath observance is proof of that fact." Catholic Record of London, Ontario, September 1, 1923”.
When you honor Sunday, as the Lord's day, you are not honoring God, you are honoring the traditions of man and worshiping the Beast. And what does God say about that?
Mark 7:7-8 In vain they worship Me, teaching as doctrines the commandments of men.' "For laying aside the commandment of God, you hold the tradition of men...
Official Statement of the Catholic Church
“Sunday is founded, not of scripture, but on tradition, and is distinctly a Catholic institution. As there is no scripture for the transfer of the day of rest from the last to the first day of the week Protestants ought to keep their Sabbath on Saturday and thus leave Catholics in full possession of Sunday.” Catholic Record, September 17, 1893.
When you honor Sunday instead of Saturday you are worshiping the beast because it's the Beast who made the change, not God.
Listen to what God says, not what I say, about those who worship the Beast.
Revelation 14:9-10 Then a third angel followed them, saying with a loud voice, "If anyone worships the beast and his image, and receives his mark on his forehead or on his hand, "he himself shall also drink of the wine of the wrath of God, which is poured out full strength into the cup of His indignation. And he shall be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb.
Notice you can have the mark of the the Beast on your forehead or your hand. The forehead is is the part of the brain where worship takes place and the hand is symbolic for your works. In other words, you may not be wroshiping Papal Rome, you may even speak against the Papacy but you can be obeying the Beast by what you practice as seen in your works. Sunday observance is a practice that did not come from God but is honored by just about every Christain denomination in the world.
