'Seven Churches' in the Bible

John to the seven churches which are in Asia: Grace be unto you, and peace, from him which is, and which was, and which is to come; and from the seven Spirits which are before his throne;

Saying, I am Alpha and Omega, the first and the last: and, What thou seest, write in a book, and send it unto the seven churches which are in Asia; unto Ephesus, and unto Smyrna, and unto Pergamos, and unto Thyatira, and unto Sardis, and unto Philadelphia, and unto Laodicea.

The mystery of the seven stars which thou sawest in my right hand, and the seven golden candlesticks. The seven stars are the angels of the seven churches: and the seven candlesticks which thou sawest are the seven churches.

“To the angel (divine messenger) of the church in Ephesus write:“These are the words of the One who holds [firmly] the seven stars [which are the angels or messengers of the seven churches] in His right hand, the One who walks among the seven golden lampstands (the seven churches):

"And write [this] to the angel of the church at Sardis: These are the words of Him who has the seven Spirits of God [i.e., Jesus, who has the Holy Spirit] and the seven stars [i.e., the seven angels of the seven churches. See 1:20]: I know about your deeds, that you have a reputation for being [spiritually] alive, but you are [really] dead.
