That is the big question, isn’t it? And it is one I am in the midst of trying to answer myself. However, as a start, I would recommend trying to find the Church whose beliefs and practices most closely match those of the Early Church. Then, I would see if this Church showed a clear link with this Early Church and was not just a modern group trying to create a Church based on their new interpretations of what they *think *the Early Church was like. That should narrow it down a bit…
Indeed!

Great thoughts!
I am reminded about the warning: “If you ever come across the perfect church, do not join it. You will wreck it.”
Naturally, this is speaking of only earthly churches!
Yes. And, could it be that this “actual body of Christ, not a mere earthly thing, but something bigger and better than what we have on Earth” could be all of this and be a visible Church at the same time? I imagine that you probably would agree that this was true of the Church during the days of the Apostles?
It could well be, apart from the idea that Christ’s body -
The church - would not be filled with sinful people, but with forgiven and washed-clean people. I think the “now-but-not-yet” idea gets into that well.
I would say that the church right after Jesus was definitely part of this “church”, but it was in no way limited to those of the day. It was always more than that - for Abraham and Moses etc were as much members of that church as we today are.
So, did the 1st C church = the “body of Christ” church? No. But it was a subset of said church.
Which is why today I am happy to say that the Roman Catholic church =/= the “body of Christ” church, and nor does any protestant church. The body of Christ is made up from all those who belong to God from today, from the past, and from the future.
If so, is it conceivable that this ancient visible Church could have maintained its “visibility” down through the centuries?
Well, my answer above was more “no”, but still - no. Yes, we still have people who are members of that church, but we are still sinful and fallen, and thus there will always be false doctrines and heresies taught. We should be on guard against this, so that we may stamp out the false teachings. But a single church still existing down through the centuries? No. The major splinters that has happened, the smaller fractures, the internal strife all show that this is just an earthly church.
And, if it has done so, would not its traditional interpretation of Scripture be more reliable than my own?
If it had dome so? Absolutely! And there would be no problems, no issues, no false teaching, no abuse within it, no leaders who were sinful, no members who were “non-practicing”…
Clearly, there is no such church on earth
And, if this Church says that there is an authoritative Tradition of which Scripture is a part, though not the entirety, is that not at least worth considering?
If there were such a church. Which, from the beginning of these questions, I have said “no” to.

Would you want to continue that discussion? I can have a read through and offer my thoughts, but it seems to have been quiet for a while now…?
