Jesus Christ was very clear when he said "MY Church", why would you want to pluralize something that God clearly said was singular. Additionally, the Church does not teach that Orthodox or Protestants are outside salvation; Innocent III was very purposeful saying "Church of the faithful," our faith is in God.
As far as Unam Sanctum, are you suggesting that Jesus Christ was LYING when in Matthew 16:19?
Just quoting the popes.
I didn’t say it or make it up.
It jives with what I was taught growing up as a Catholic.
No, Of course I’m not saying that Jesus lied.
However, there is more than one interpretation of that verse.

Those popes were very specific about it being the Roman Catholic Church.
I would like to see some source that indicates that Pope Innocent had some other church in mind than the Roman Catholic church, of which he was the head.
What other churches were in existence in those days to which he might have been referring?
