That's what many people think who've bounced around between denominations and alight on one that insists that it is the only truth and, therefore, the members are the only real Christians. Eureka. It gives a sense of security to them.
The fact is, though, that what you've written here is no more true than that Joseph Smith found golden plates, that the Apostolic church apostasized only to be rediscovered by the Jehovah's Witnesses, or that Ellen G. White was a prophet who finally got Christianity right--and all those churches' followers are as certain of it as you are of your belief.
Christ founded a church, not a club. The New Testament itself teaches this when it says that the foundation of the church is the "household of God." That's all the true believers. It doesn't say "the Church at Rome (or Alexandria or somewhere else), not those other ones."
But at least you were right to point out that the word "catholic" (originating well after the founding of the first churches) meant a characteristic, and was not a name of any denomination.
Really?????
Are you really....(sheeesh, never mind, I don't want to devolve to insults here).
I cannot understand how, for the life of me, you can look at the historical and chronological progression of that first organization, which had only one hierarchy and one set of leaders, and somehow insist that devolution from that particular organization constitutes remaining in the Church.
Look, guy, it is either the Holy Orthodox and Rome left them, or it is the Catholic Church with Rome as the head of 23 different rites and Orthodoxy left them. I am trying to figure that one out right now.....
but Anglicanism, sir, is not even in the club! Not a part of either one of them. Considering that English Catholics were at one time part of the Western Church, you were once part of the Church by being headed up by Rome. But when Henry the VIII's passions overwhelmed his common sense and he broke ties with Rome....
you guys were out! No longer part of the Church. To make an analogy, it would be like being part of the English Crown and then breaking away, yet still trying to claim that you are English. Nope....it's called the United States of America, and while there is a certain connection in language and culture, the Crown has no governance over us, hence we are not a part of England.
Rome has no governance over the Anglicans (except for the Anglican Ordinariate) and hence, you are not part of the historic Church.
Now you can twist history until you are blue in the face, but the fact is that Rome has apostolic succession which the other named groups you gave do not. JW's, Mormons, Protestants of any stripe, Fundamentalists, Anabaptists, etc, cannot claim to have an unbroken line of authority which reaches all the way back to the Apostles. Only Constantinople and Rome can claim that and have history to prove it. The rest did not exist until a minimum of 15 centuries later.
And in the operational principles of a covenant relationship, the fifth working principle -succession - is in effect here. You have no succession. Period. Covenantal authority is handed down by the laying on of hands. Once that is broken - pffffffft! You're done! That is why in the Scriptures being the first born son was no small deal. The first born got EVERYTHING in covenant inheritance!
So dream on, sir. I wouldn't wish to interrupt your little fantasy!
