Matthew Poole and continuators on Revelation 3:6

6 He that hath an ear, let him hear what the Spirit saith unto the churches .

The common conclusion of all the Epistles. See the Notes on v. 7, 11, 17, 29. Those who make these Churches Typical, and the Epistles Prophetical of the complexion of all the Churches of Christ, which shall be to the end of the World, say the Church of Sardis typifieth those Reformed Churches after the year 1560, that should cast off Antichrist, but continue in a more imperfect state, contenting themselves with a bare disclaiming Antichrist, but not rising up to a perfect Reformation.
