Precious friend, thanks for your Valuable Input - our brief basis:The same Greek word, apostasia, translated as "falling away" in 2 Thessalonians 2:3 is used in one other verse:
Acts 21:21 And they are informed of thee, that thou teachest all the Jews which are among the Gentiles to forsake (apostasia) Moses, saying that they ought not to circumcise their children, neither to walk after the customs.
It's used here to refer to Jews departing or falling away from belief in what Moses taught. I don't see any basis for thinking it was used in any other sense (a falling away from the faith) in 2 Thess 2:3.
The Falling Away = “depart” from the faith? Or?:
“The Departure From Earth”?
"falling away" = apostasy? However, we, since the beginning, have had "rebellion against God!"
However, with "The" Definite Article in the Greek = "hee apostasia," we "could Now interpret" =
"The Falling Away ( The "Snatching Away" or "The Catching Away ) From The Earth,
By The LORD Himself To "Gather us Unto Himself" to "Be Caught Up" With The
Resurrected "dead" in CHRIST, To "Meet The LORD, In The Air!" (2Th 2:3, 1Th 4:16-17)
Amen.
Our E-x-p-a-n-d-e-d basis for "The Departure" = God's Removal Of His Body!
