not to let your minds be too easily unsettled or wrought up, by any message of the Spirit or any utterance or letter purporting to be from me, to the effect that the Day of the Lord has already come.

So stand firm, brothers, and hold fast to the instructions you have received from us, whether by letter or by word of mouth.

If anyone refuses to obey what we have said in this letter, mark the man and do not have anything to do with him, to make him feel ashamed.

This greeting is in my own hand, Paul's; it is the mark in every letter of mine. This is the way I write.
