There wouldn't be if original Christianity had not had apostate "grievous wolves" to arise from among themselves "speaking perverse things, to draw away disciples after them," Acts 20:29,30.
There wouldn't be if the original good seed first sown, had not had tares to arise among the wheat (parable of the wheat and tares, Matt. 13).
There wouldn't be if Christianity had not apostatized, becoming more and more eclectic, more and more paganized, more and more Romanized, until the rise of the Roman Papacy, a tyrannical totalitarian institution.
From the days of Wycliffe, Huss, and Luther, Christianity has been characterized by its effort to overthrow the paganism introduced into it, trying to get back to the original good seed first sown before the eclectics had corrupted the field. The Protestants represent that gallant effort.
So don't trash the gallant effort of Protestants, there wouldn't be Protestants if the RCC had not become the chief representative of eclectic paganized Christianity. The Papacy is tares, not wheat.
I’m not, I wouldn’t trash all the efforts of all the Protestants by any means! Of course I won’t agree that we have a monopoly on tares, though we sho’ ‘nuff have plenty. But ... well, the hymns alone are testimony to the Holy Ghost moving among Xtians not in communion with the Holy See. And most of my theological learning, such as it is, happened at a (Calvinist leaning) Episcopal seminary in the lost days when they believed in God and studied Scripture.
But unity of teaching would be nice. There has been fermentation with some pretty wild grapes from the beginning, hasn’t there?
