Who is Paul discussing in 2 Thessalonians 2?

[PeterAndroz]

Since the first appearance of Jesus, the kingdom of God was taken away from Israel, BUT it was then GIVEN to ALL who are born again into a NEW creature.
They are NEITHER Jews OR Gentiles, but rather A NEWLY CREATED NATION.

So then, ever since PENTECOST, it's NO LONGER about Israel as a nation or any Gentile nation, but rather the NEW nation of Born again Saints.

Mat. 21:43
Therefore say I unto you [the nation Israel], The kingdom of God shall be taken from you, and given to a [different] nation bringing forth the fruits thereof.

2 Cor. 5:17
Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.

Galatians 6:15
For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but [rather] a new creature

"""So then, ever since PENTECOST,""
From your understanding what verses teach how the HS was received at Pentecost (early Acts) compared to today ?
Please list the relevant verses
