Is it your opinion that the Roman church is the sole legitimate heir to the apostolic tradition? Is that what you believe?
I can see where you might be confused about the nature of the kingdom of Christ is you hold that view.
I realize you are desperate in wanting to tag all non-dispensationalist as Romanist or some other errant position (in your view), but it really wont work. I suggest you take your own advice from an earlier post that appears to have been removed by the RM.
It certainly was in AD 70 when Christ allegedly "removed the kingdom from old Israel and its leadership and passed it on to the holy nation under the authority of the apostles".
The RCC was not challenged in regard to its apostolic authority for nearly 1000 years. Clearly the RCC would have a legitimate claim to being the sole legitimate authority for Christ's kingdom if Christ actually set up his ruling kingdom on earth in 70AD.

No. Using your logic and theology, Reformation Preterists would not be Romanists. They would be apostates.
