I do not think he meant something that would be contrary to other things he said and taught.
OK, let's say your link is 100% correct: That upon the Rock of revelation (& personal confession), Christ is building His Church upon that.
How would this interpretation change what you said in post#64?:
In My Not-So-Humble Opinion, churches and religions are for those who cannot, or choose not to, believe in God. The church or religion serves as an idol for those people to worship until they are ready to believe, if ever. People can flee from one church to another, from one set of lies to another, and they will still find that any group of people will be corrupted just like any other group of people...Christ had pretty much the same opinion of organized religion as I have expressed above.
Matthew 16:18 assumes an ever-durable church of Christ...one NEVER given over to TOTAL apostasy.
(Now that doesn't mean every church is true, just as every green $100 bill portending to be authentic is genuine currency...yes, counterfeits exist in ALL facets of life).
Matthew 16:18 seems to assume, from your implied post, that a church built upon a "rock of revelation" would generationally persevere.
So have you sought out that church? And, why does your post #64 seem to assume that 100% of churches are...
...geared for unbelievers who remain unbelievers...?
...idolaters who remain idolaters...?
...full of corrupt people who remain corrupt?
It seems to me, Christ doesn't agree with your "opinion" that 100% of people in churches remain corrupt, remain idolaters, and remain unbelievers.
JESUS: Hey Smith! Remember that boast you made about doing more than even I had done to hold the 'church' together?
JOSEPH SMITH: Where am I?
JESUS: Don't you remember? A few seconds ago you were in that jail.
JOSEPH SMITH: Oh; yeah; but where am I NOW?
JESUS: Don't you remember? Does bang - bang ring a bell?
JOSEPH SMITH: Oh; yeah - that crummy gun I had was about USELESS!
JESUS: I hope you left instructions on how to hold your church together.
JOSEPH SMITH: Dang! I knew there was SOMETHING I was forgetting!
JESUS: Looks like there's a power struggle going on down there.
JOSEPH SMITH: Yeah; there was always SOMEone who wanted the power that I held - especially over the LADIES - wink wink.
JESUS: No need to worry about that now; remember what my friend Matthew wrote down?
JOSEPH SMITH: This? At the resurrection people will neither marry nor be given in marriage; they will be like the angels in heaven (Matthew 22:30)
JESUS: That's it.
JOSEPH SMITH: I thought that was mistranslated.
JESUS: Nah - it was right.
JOSEPH SMITH: Oh well; it was fun while it lasted. My buds will still get it on with the girls.
JESUS: Uh; I'm sorry; in just a few more years; your followers will cavein to the United States government and abandon the 'Eternal Covenant' that you came up with.
JOSEPH SMITH: ME!? YOU are the one that told me to do that!
JESUS: Sorry; but you must have mistranslated what I told you. What part of Do NOT commit ADULTERY did you not understand?
JOSEPH SMITH: mumble....
JESUS: What did you say?
JOSEPH SMITH: Oh, nothing.
JESUS: Well; it was interesting talking to you; but now I must get back to perparing a place for those who believe in Me.
JOSEPH SMITH: Oh, yeah; the Celestial Kingdom.
JESUS: No...
JOSEPH SMITH: The Telestial one?
JESUS: Nope.
JOSEPH SMITH: SUREly not the TERRESTRIAL one!!
JESUS: Nope. Didn't you read that the mind of man had NOT conceived of it? Paul wrote it down in 1 Corinthians 2:9.
JOSEPH SMITH: I thought that was mistranslated.
JESUS: No; it wasn't.
JOSEPH SMITH: You SURE?
JESUS: Yes. Now I must be going: what did you say your name was again?
JOSEPH SMITH: Joseph Smith.
JESUS: Hmmmm. According to my Heavenly FAITHbook, you didn't sign in as one of my friends - sorry, I never knew you.
JOSEPH SMITH: But....
