¹ We ask you, brothers, with regard to the coming of our Lord Jesus Christ and our assembling with him, ² not to be shaken out of your minds suddenly, or to be alarmed either by a “spirit,” or by an oral statement, or by a letter allegedly from us to the effect that the day of the Lord is at hand. ³ Let no one deceive you in any way. For unless the apostasy comes first and the lawless one is revealed, the one doomed to perdition, ⁴ who opposes and exalts himself above every so-called god and object of worship, so as to seat himself in the temple of God, claiming that he is a god.
–2 Thessalonians 2:1-4 (New American Bible)–
