So you admit that Catholicism is a denomination.Oh so denominations first started when the Orthodox Christians refused to recognize the Catholic pope and the Orthodox claimed that the Latin branch, Catholicism, was seeped in heresy. The Catholics "protested" against that and thus became the first "Protestants"--according to your way of thinking.Nope, denominations were invented to differentiate one dissident group from the others.
(Pretty valid argument from the Orthodox Christians seeing what Catholicism believes today)
Here is your test question Oh Great Catholic History Scholar: What year was it when this "Great Schism" happened?
I'll give you time to call your priest or ask FR's resident pre-Canonized saint.
approx 1053...what's the point??
