Extra ecclesiam nulla salus = There is no salvation outside the Catholic Church and fancy that, it means what it says. You are the one who can't accept this.
You profess the "re-formulated" version of the 20th century theologians and Novus Ordo Catechism - and either don't even realize it or you do realize it yet keep yapping about it anyway as if the "re-formulated" version is the real version.
You really do need to listen to the sermon in the OP.
