The Body of Christ yes, some non-denominational ekklesia of Christ that "has been consistent since the time of Christ" ...? And one whose theology is the same as yours, down through history?
That can be claimed, but: No evidence, no history.. The *real* Christians left no trace?
WE'RE HERE STILL.
Sola Scriptura protestants have been here since Luther; but, I don't think you can find your non-denominational ekklesia even that late.
