Thanks for your timely question. Lots of Christians (and even some non-Christians, according to a recent Washington Post article) are particularly fascinated with the topic of the end times nowadays.

It's interesting that the word "rapture" never appears in Scripture. Modern theologians have, at the same time, imposed a foreign meaning onto the Second Advent of our Lord. So in essence many theologians and ministers believe in something totally different from the Scriptural teaching, and they have labelled this doctrine "the Rapture."

We believe in the Second Coming of the Lord Jesus Christ, which is known throughout the Word of God as the "Day of the Lord." This day will be filled with terror for non-Christians as Christ condemns them to eternal torment, but it will be a day of victory for God's people. Christ will come in glory, with his angels, and the dead in Christ will rise first, followed by believers. When St. Paul in I Thessalonians speaks of the Second Advent, he's probably making use of a common event in his day -- the greeting of a visiting dignitary by the people of a town. When a dignitary would come to town, the townsfolk would meet him outside the city gates and lead him back into the city. It was a splendid event, fit for a king.

That's the point Paul is making in I Thessalonians: when Christ comes again to judge the living and the dead, and to end space and time as we know them, he will be met with open acknowledgment of his glory (cf. Philippians 2:10-11). And to comfort the Thessalonian believers, Paul informs them that the dead in Christ will not be left behind. They actually will meet the Lord first! But you and I should not push Paul's metaphor too far -- just realize that the Lord will return, and it will be a glorious and cataclysmic event.

Many Protestants, influenced by the fantastic (and non-biblical) "Left Behind" series and by "Dispensationalist" teaching (as articulated by Ryrie and Walvoord and others), have argued for more than one second coming of Christ, and they hold to something called the "Great Tribulation" that will precede one of the returns of Christ. Yet the New Testament, especially the last two chapters of the Revelation, holds that the church will increase throughout history until finally she endures a great falling-away, which will be followed immediately by the Day of the Lord. After the general resurrection and the judgment, the unrepentant will be condemned to eternal punishment while believers will reign with Christ in the New Heavens and New Earth.

So to answer your question, yes, we as Reformed Protestants hold to the historic view of the end times: thus we believe Christ will come again to usher in the New Heavens and New Earth. But there is only one Second Coming, and it likely will look very little like many Christians assume.

Even so, come, Lord Jesus!
