“The Day of the Lord” versus “the Day of Christ”

Paul had to correct the ‘lies’ of the false teachers by his epistles to the Thessalonians.

Paul said he was ‘reminding’ the Thessalonians (2Thes. 2:5) of the sequence of specific events to be expected, so they could recognize that those events had not yet occurred, evidencing that they had not missed the resurrection (Rapture) of the church to glory.
