Revelation 2:1

the angel of the church of Ephesus Some think that this would be St Timothy, and go so far as to find in St Paul's Epistles traits of his character analogous to those here noted. But even if the "Angel" here be a bishop, it is likelier that he would be one appointed by St Timothy, if not by St John himself. 2 Timothy 4:9; 2 Timothy 4:21, compared with Titus 3:12, seems to prove that permanent residence in one diocese was not implied by the apostolical commission which St Paul, toward the end of his life, gave to his disciples.

he that holdeth the seven stars Ephesus being the chief city and, to some extent, the mother Church of the district, the Lord addresses the Church there in the character of Lord of allthe Churches: as though (to illustrate by the later organization of the Church) he addressed all the Churches of the Province in the person of their Primate.
