The Messiah personally addressed those seven churches in Asia, each as a genuine "church." Similarly, the Apostle Paul personally addressed the church at Corinth. These were bona fide, genuine churches
That was never denied, but that this does not equate to all those in these organic candlestick communities being true believers. Sorry if that was not clear enough for you.
the one holy catholic apostolic church,
Not as translating to the church of Rome that you belong to. That is the issue.
that a genuine church may have its candlestick removed
That was not denied but was affirmed.
Here is where OSAS falters. The Messiah personally addressed this church [bold emphasis throughout mine], as those he loves. How could he spit them out of his mouth except they were already in him ? And unto the angel of the church of the Laodiceans write; These things saith the Amen, the faithful and true witness, the beginning of the creation of God; I know thy works, that thou art neither cold nor hot: I would thou wert cold or hot. So then because thou art lukewarm, and neither cold nor hot, I will spue thee out of my mouth. Because thou sayest, I am rich, and increased with goods, and have need of nothing; and knowest not that thou art wretched, and miserable, and poor, and blind, and naked: I counsel thee to buy of me gold tried in the fire, that thou mayest be rich; and white raiment, that thou mayest be clothed, and that the shame of thy nakedness do not appear; and anoint thine eyes with eyesalve, that thou mayest see. As many as I love, I rebuke and chasten: be zealous therefore, and repent. Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me. To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne. He that hath an ear, let him hear what the Spirit saith unto the churches.
