Obviously it is a source used by amateurish Protestant apologists too, but it isn't the source I used. Besides, even if the number were only 10,000, or 1,000 individual sects, schisms, denominations, or what have you, you have a situation in which the only thing that they can collectively agree on or have in common is that they are different from Catholicism. Otherwise the each have their own alter pontiffs or latter day Calvin's redefining, reinterpreting and misrepresenting Scripture, Tradition and their own worldly intentions.
Of course not. It was someone else's. What else is new?
