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
I believe the Lambs Book of Life must be sealed with the seven seals for the first resurrection to take place. Once the entire church is sealed it will be time for the trumpets to sound and
51 Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
53 For this corruptible must put on incorruption, and this mortal must put on immortality.
54 So when this corruptible shall have put on incorruption, and this mortal shall have put on - 1 Corinthians 15
Once those trumpets sound, and the tribulation occurs as outlined in Revelation, then we will return with Christ to reign with him a thousand years...
Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years. - Revelation 2:6
