Who Is the Man of Sin?

Paul connects the man of sin with a falling away and self-exaltation in the temple of God. One interpretation understands the temple reference here as the professed Christian church rather than necessarily a rebuilt building in Jerusalem.

Second Thessalonians 2 says the mystery of iniquity was already active in Paul’s day, while a restraining influence delayed its fuller manifestation. Historicist readings often connect the restraint with the Roman political order. The restrainer’s identity remains debated; Paul does not explicitly name it.

Daniel 7 and Revelation 13 also describe self-exaltation, persecution, and a power opposed to God. Comparing their features with Paul’s description builds the argument for a connected prophetic system. This is a system-level interpretation, not permission to label a current politician or condemn individual believers. Paul’s conclusion points to Christ’s victory at His coming.
