'Seven Churches' in the Bible

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

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

The mystery of the seven stars which you saw in my right hand, and the seven golden lampstands. The seven stars are the angels of the seven churches: and the seven lampstands which you saw are the seven churches.
