That ye be not quickly tossed from your mind, nor be put in alarm - either by spirit, or by discourse, or by letter as by us, as that the day of the Lord, hath set in:

Who puts himself against all authority, lifting himself up over all which is named God or is given worship; so that he takes his seat in the Temple of God, putting himself forward as God.

Then the representative of lawlessness will be uncovered, and the Lord Jesus will destroy him with the breath of His mouth and put a stop to his operations by His appearance and coming;

For this reason God is sending on them an energy of delusion, that they should put faith in a falsehood;

and if any one should disregard what we have prescrib'd, signify it to us by letter, and don't converse with him, that he may be put to shame.

You are not to treat him as an enemy, but to put him under discipline, as a brother.
