2:12 "And to the angel of the church in Pergamum write:

The One who has the sharp two-edged sword says this:

And to the ANGEL of the church in Pergamum write: the ONE who has the sharp two-edged sword says this:

Christ is the author of this letter - Revelation 1:16.

The Lord will use His sword to fight the BALAAMites (Revelation 2:14) and the NICOLAITANS (Revelation 2:15).

This verse may allude to the fact that Pergamum under Roman control was given the rare power of capital punishment (ius gladii). This power is symbolized by the sword.
