Then the Catholic Church is the legitimate authority of Christ on this earth.
If Christ literally set up the Millenial Kingdom in 70 AD, then the Reformation was an act of apostasy against the legitimate earthly ruling authority of the Kingdom of Christ on earth.
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.
