The Day of Christ vs The Day of the Lord
This is a special distinction that occurs in the Textus Receptus. That is a series of Greek New Testament texts that many older English Bibles are translated from. Many other more modern Bibles are made from manuscripts that do not have this distinction. Instead of fighting about which single manuscript is the right one, perhaps the an advantageous position to hold is to use all available manuscripts to see the most accurate rendering of the text. Here, in this instance that is being brought out, the Textus Receptus reveals an amazing secret.
The Old Testament prophets spoke much about “the Day of the Lord”. In every instance this is mentioned in a negative fashion, about judgment and darkness. When Paul writes to the church of the Thessalonians the first time, he talks about this Day of the Lord.
First, Paul explains about the catching away of the Church. Something they were very concerned about was that their relatives and friends that had already passed away might miss this great event. Paul explains that the dead believers will not miss it. In fact, they will participate before the living saints do (1 Thess 5:15).
so, then, comfort ye one another in these words. (1 Thess 4:18)
After receiving this letter the Thessalonians experienced a great amount of persecution. Things were so bad that some speculated that the day of the Lord, the Day of wrath that Paul had taught about, had come. Not only that but the text suggests that possibly someone had forged a letter with Paul's name saying authoritatively that the Day of the Lord actually had come.
The first mention of this Day is found in the book of the prophet Isaiah.
For the day of the LORD of hosts shall be upon every one that is proud and lofty, and upon every one that is lifted up; and he shall be brought low: (Isa 2:12)
No wonder that they were afraid of the Day of the Lord. Paul writes a second letter to them because of their new concerns.
that ye be not quickly shaken in mind, nor be troubled, neither through spirit, neither through word, neither through letters as through us, as that the day of Christ hath arrived; (2 Thess 2:2 YLT)
Paul says, Brothers, the Day of the Lord has not arrived yet. You have not missed anything. In fact, an earlier different day has not yet arrived, either, the Day of Christ.
Paul had taught that they should encourage one another in regards to the Day of the Lord because they were going to be exempt from the horrors of it. Like all the Old Testament references to it, he indicates that this is something terrible. He says that the arrival of this Day will be sudden destruction using terms like “night” and “darkness”. The terrible Day of the Lord would actually be easy to calculate for those who know the prophetic scriptures. For those who do not know anything about the Bible, that Day comes “as a thief in the night”. By contrast Paul says that the Believers in Thessalonica are not in any way related to night or darkness because they are sons of the day and of the Light. Paul said they were not in darkness (1 Thess 5:4) as others.
By contrast the Day of Christ is unknowable, except for signs that indicate it is near at hand. The Day of Christ is the Gathering/Rapture/ Resurrection event.
1 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him,
2 That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand (or has arrived). (2 Thess 2 KJV)
Paul defines this “Day of Christ” as a coming of Jesus Christ and our gathering unto Him. For the Believer, this is the opposite in nature than the Day of the Lord is for unbelievers.
If I could summarize my understanding of Paul's message to the concerned Thessalonians:
Brothers, don't worry about the Day of the Lord. You won't participate in it anyway. Also, don't worry about the departed brothers missing the coming of Jesus for His people (the Day of Christ). They will be participating in it before living persons will anyway. Also the Rapture is not imminent (for those in the first century). Two great signs must occur first. There will be a great falling away from the faith and, secondly, the Man of The Destruction must be revealed (2 Thess 2:3).
Today, we do not want to hear that. I, personally, do not want to hear that. But apparently that is what the Thessalonians were told.
In 1 Thess 4:18 Paul's command is to encourage each other about participating in the Day of Christ (comfort) and 5:11 says to encourage each other about missing the Day of the Lord (wrath).
In 2 Thess 2:2 The Day of Christ is the rapture (v1). Encourage each other in that!

The Day of Christ and the Day of The Lord. Are they 2 sides of the same coin? Perhaps but I don't see much value in arguing their connectedness other than making room/allowance for all the manuscripts. Their distinction tells us a lot, in my opinion. The real value is in seeing 1 side of the coin at a time.
