If I had to take a stab of the seven stars (messengers) to the seven candlesticks (churches)...
Original messenger - Church
1. Peter - Messianic
2. Paul - Early Gentile
3. Constantine - Greek Orthodox
4. Theodosius I - Catholic
5. Martin Luther - Protestant
6. John Wesley - The revived church (Methodist - Pentecostal)
7. Robert Shuller - The Country Club
One Church... Millions of congregations...
1. Ephesus - Messianic Jewish Church
2. Smyrna - Oriental Orthodox - The Roman persecutions were ten
3. Pergamos - Greek Orthodox - Pergos... A tower... Needed in the dark ages
4. Thyatira - Catholic - Middle ages
5. Sardis - Protestant - A sardis is a gem... Beautiful,,, Not much spiritually
6. Philadelphia - Wesleyan - Too bad the revivals didn't last longer
7. Laodicean - Word of Faith - Rich and have need of nothing?
Seven candlesticks - Seven generalized congregation - All unique - And Christ walking in the midst
Seven seals - Those names written in the Lambs Book of Life
Seven stars - Those messengers to the congregations
Regarding who is sealed in the Lamb's Book of Life...
3 And no man in heaven, nor in earth, neither under the earth, was able to open the book, neither to look thereon.
4 And I wept much, because no man was found worthy to open and to read the book, neither to look thereon. - Revelation 5
There is no man who is able to look into the Lamb's Book of Life and figure out whose sealed... unsealed... Or who has never been sealed. All of that is Heavenly business.
21 Peter seeing him saith to Jesus, Lord, and what shall this man do?
22 Jesus saith unto him, If I will that he tarry till I come, what is that to thee? follow thou me.
23 Then went this saying abroad among the brethren, that that disciple should not die: yet Jesus said not unto him, He shall not die; but, If I will that he tarry till I come, what is that to thee? - John 21
