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).
Date of birth of Jesus
The earliest source stating 25 December as the date of birth of Jesus is likely by Hippolytus of Rome, written very early in the 3rd century, based on the assumption that the conception of Jesus took place at the Spring equinox which he placed on 25 March, and then added nine months – festivals on that date were then celebrated. 25 March would also roughly be the date of his crucifixion, which ancient Christians would have seen as confirming the date of his birth, since there was a notion that the great prophets were conceived into the afterlife on the same date they were conceived into the world. John Chrysostom also argued for a 25 December date in the late 4th century, basing his argument on the assumption that the offering of incense in Luke 1:8–11 was the offering of incense by a high priest on Yom Kippur (early October), and, as above, counting fifteen months forward. However, this was very likely a retrospective justification of a choice already made rather than a genuine attempt to derive the correct birth date.
