Hi Ted,
If you are looking for proof in the scientific sense, I don't think it exists, but God never confined His scriptures to the limits of our scientific proofs. The Seven Church Ages, if they are to be seen, must come from a realization that God "winks" as He sets forth the textual account, letting you know there is somthing much larger going on than meets the eye.
For example, in the
Isaiah 14 passage, the context begins locally, with the king of Babylon, but then zooms way out into the eternities where Lucifer's actions are described by comparison.
In the case of the Seven Churches, the context starts out in the grand eternities, and then surprisingly applies these grand themes and symbols to a small group of relatively insignificant churches in Asia. If you were a Jewish Christian in Jerusalem reading Revelation for the first time, you would surely scratch your head. You are carried into John's vision of the heavenly temple, where you see what appears to be MEnra, the Seven Golden Lampstands, and the Seven Stars representing "THE" Seven churhes. So far so good, you understand those symbols, but then you are forced to apply these grand themes solely to a few small churches in Asia, and reckon with the omission of many more important churches from this seemingly expansive beginning. Where is the church in Jerusalem, for example? Where is ITS Lamp and Star? How about Antioch, where Christians were first named? Where is Rome? Surely these great churches should find a prominant place in any such vision. As God sends His final message to the churches as He is about to close the cannon, does He have nothing to say to Jerusalem, or Antioch? He is going to send a message to "seven" and only "seven" no more no less, and these humble little groups are the ones?
Then as you get into the letters themselves, you find them rich with symbolism woven through the more simple language, which continues to raise more questions that seem
designed to make any Christian stop and ponder. Where is "Jezebel" in the church? Where is "Balaam?" Where are the "Jews" who make up a "Synagogue of Satan?" You learn that a Lamp can be removed from its place.
But I am in the church in Jerusalem, you think--
so I don't have a Lamp to worry about being removed, right? But that can't be, that would be inequitable treatment--these principles have to apply to everyone, not just the church that is mentioned.
If that is the case, just how far does the application project? To all churches everywhere? To all Christians? To wherever the "shoe fits" as they say?
These things are God's "winks" telling us to not have "tunnel vision" as we read these mysterious letters, but look out and around, and see the bigger picture. The first century Jewish Christian only had the local situation to go on, but he could see hints at at a larger application in the text already. We now have 2000 years of church history to look back on, and the perspective of Revelation as a prophetic book, the final book of the cannon, where we might find--if we are to find it anywhere-- a love letter to equip the church for all the challenges that it would face as it begins its long and unexpected journey through the centuries.
Then we notice that there are many things in the letters that seem to roughly sketch the progress of church history, down into the dark ages, and back up through the reformation into the present. Given the mysterious nature of the letters, perhaps God meant for us to probe this a bit, and see if in the end, there is a letter that applies specifically to us, and to our situation, when the coming of Christ is near, even right at the door-- knocking as it were, so that we may know and perform the most important and necessary response in our time.
None of that proves there are Seven Church Ages, but yet, I believe the better part of prudence would instruct us to examine this possibility very closely, for it could be that our own fate and destiny as a church is at stake here. If so, the letters to the churches are lifted out of the realm of old dusty history, where we may study them from our safe cozy place "behind the glass," to the surprising revelation that we are in fact living the story ourselves, and the applications we find are no longer merely academic, but desperately important to us.
Shalom,
Ari
