I'm not going to trust that you actually have a strong grasp of Greek grammar. I don't believe that.
2 Thessalonians 2:9 The coming of the lawless one is according to the working of Satan, with all power, signs, and lying wonders, 10 and with all unrighteous deception among those who perish, because they did not receive the love of the truth, that they might be saved.
This indicates that before the coming of the lawless one (man of sin), "the working of Satan, with all power, signs and lying wonders, and with all unrighteous deception" is not occurring, but then it is occurring after the coming of the lawless one. So, what is being restrained is "the working of Satan, with all power, signs and lying wonders, and with all unrighteous deception". Lawlessness, in other words. If lawlessness is not what was being restrained, then why does Paul speak of a mass falling away occurring in the future? Why wouldn't there be a mass falling away from the faith even while Paul was writing the letter if lawlessness was not being restrained at that time?
Because the papal system (little horn of Daniel 7,8 and 11), did not exist in the 1st century. As I mentioned to another poster earlier, there were those that preached a different gospel even within the Apostolic period. But the lawless one would COME OUT of the 4th kingdom much later.
The mass falling away after a Paul’s time and the little horn would not come to full power until the early 6th century. Then, they would indeed preach a very different gospel.
Can you possibly imagine anyone claiming the following;
1) salvation is only through their church,
2) must obey pope,
3) he represents God on earth,
4) he claims equality with God,
5) he can forgive sins,
6) must obey their sacraments,
7) Mary as co-mediator or worse,
8) pray to saints and Mary,
9) ability to change God’s 10 commandments,
10) change the Sabbath day - the only holy day He created,
11) perhaps a hundred other teachings, practices, ceremonies, etc., that Jesus never would allow or call out.
Everyone is seriously looking for and expecting a real boogeyman (Satan himself), but that is not what is in the Scriptures. Satan will indeed be seen but ONLY at the very end when God pulls him out of the abyss and destroys him, his followers and all mankind who were also brought out of their graves who rejected the Messiah. That is the end. Satan is doing his evil and has been for 6000 years, and God is certainly no going to allow him to come forth at the end. He is and has been doing his thing within the constraints set by God for the past 6000 years.
The 7 year tribulation, the end time coming of a Satan like figure, etc., is not in scripture. All of this began with the counter reformation practices of the Jesuits in the 16th century, and they have continued to promote this till today. Its beginnings came from their need to remove the label of the “little horn” from the papacy.
Is there any person / organization / religious group / etc., that has done more against the Kingdom of God? Who could possibly accept one that claims equality with God? Is there anything more blasphemous than that?
LOL. Why do you pretend to be a Greek expert? You're fluent in Greek, are you? I don't believe you are. Does scripture itself tell us that the key to understanding it is to have a strong understanding of the Greek language? Or does it say that we need spiritual discernment from the Holy Spirit (1 Corinthians 2:9-16)? It's the latter. Even if we were Greek experts, we would need help from the Holy Spirit to understand most of the things that we talk about on this forum. Yet, you act as if we just knew Greek as well as you think you do, we'd have this all figured out.
This:
2 Thessalonians 2:8 And then the lawless one will be revealed, whom the Lord will consume with the breath of His mouth and destroy with the brightness of His coming. 9 The coming of the lawless one is according to the working of Satan, with all power, signs, and lying wonders, 10 and with all unrighteous deception among those who perish, because they did not receive the love of the truth, that they might be saved.
You think it's the revealing of the man of sin/lawlessness that is being restrained. No, it's what happens at the coming/revealing of the man of sin/lawlessness that is restrained, and that is described in verses 9 and 10.
