I don't believe that there ever was a "great apostacy".
I know you don't, Dawn, but in the OP, FerventGodSeeker was assuming (just for the sake of discussion) that there was one and that there had also been a restoration. He was just asking that members of the various churches that claim to be the restored Church to explain why they believe it to be their church. We've had a number of discussions here on RF on the Apostasy, but none on the Restoration, so I'm really not interested in taking this one off in another direction (although I'm sure it will end up that way eventually).
The foundation isn't the church, though, in my opinion.
No, the foundation isn't "the Church," and I've never said it was. Christ said His Church was built on the foundation of prophets and apostles, so that's what I believe.
The foundation is Christ.
Christ said He is the cornerstone of His Church. That's what I believe, too.
And Christ is found within each of us. My foundation can't crumble. Take away every church...every "religion"...and we still have Christ.
Of course we still have Christ. Christians have had Christ since the beginning, but that's still not the same thing as the Church He founded.
I just don't believe that Christ placed any more emphasis on the authority of the church than he did on the authority that each believer posesses. And I can provide scripture that tells us that the believer has authority.
I know you can, but I can provide several others that say that's not the case. If Christ established His Church on a foundation of Prophets and Apostles, and Paul said that's how He intended it to function, I'm afraid I'm just not comfortable disagreeing with them.
