Contradiction with Matthew 24:36
This verse states that no one knows the day or the hour of the end, while 1 Corinthians 15:52 suggests a precise moment, "in the twinkling of an eye."
Matthew 24:36: But of that day and hour knoweth no [man], no, not the angels of heaven, but my Father only.
Contradiction with 1 Thessalonians 5:2
Describes the day of the Lord as coming like a thief in the night, implying unpredictability, contrasting with the suddenness but certain timing in 1 Corinthians 15:52.
1 Thessalonians 5:2: For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
Contradiction with 2 Peter 3:10
Also states that the day of the Lord will come as a thief, suggesting unexpectedness, which seems inconsistent with the quick and decisive timing described in 1 Corinthians 15:52.
2 Peter 3:10: But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
