Prewrath
According to prewrath, this passage clearly indicates that the coming of the Lord and the Day of the Lord are part and parcel of the same event, the coming of the Lord. First, Jesus arrives in the sky at His Second Coming, at which time He raptures all Christian believers, then His judgment during the Day of the Lord falls upon those who have disbelieved and rejected His lordship.
This is justified, according to prewrath, by the fact that Jesus places His return (Matthew 24:30–31) after the abomination of desolation (Matthew 24:15), which occurs at the midpoint of the 70th Week (cf. Daniel 9:27, Daniel 11:31). Thus, if the Second Coming and rapture occur after the sixth seal, this places this event after the midpoint but before the end (seventh trumpet).
Advent
The theme of readings and teachings during Advent is often the preparation for the Second Coming, while also commemorating the First Coming of Christ at Christmas. The first clear references in the Western Church to Advent occur in the Gelasian Sacramentary, which provides Advent Collects, Epistles, and Gospels for the five Sundays preceding Christmas and for the corresponding Wednesdays and Fridays. While the Sunday readings relate to the first coming of Jesus Christ as saviour as well as to his Second Coming as judge, traditions vary in the relative importance of penitence and expectation during the weeks in Advent.
