The earliest Christian document outside of the New Testament is almost certainly The Didache, which is also known as The Lord's Teaching Through the Twelve Apostles to the Nations. In its final chapter, the author says that in the last days, the sheep will turn into wolves and the Deceiver of the world will commit abominations that have never been seen since the world began. Is this what Paul had in mind when he wrote 2 Thessalonians 2:1-12? 

In The Final Abominable Temple, Baker traces the ideas of God's temple, abominations, and apostasy through the Scriptures. He also discusses how the earliest Christians thought and wrote about these themes. By doing so, we get a better understanding of what Paul believed would come upon the world and the Church in the times of the Antichrist. Finally, Baker highlights several ways to stay faithful to Jesus in the days when the sheep become wolves.
