“Because it seems to me that these numerous posts like this one aim to “prove” that Roman Catholicism is the only faith and that protestants are heathens worse than animists.”
Well, your understanding is wrong. Proving that the Catholic faith is true, does not make Protestants “heathens worse than animists.”
If someone proved that China was the wellspring of Asian culture, that wouldn’t make the Japanese hispanics. That’s basically what your understanding seems to suggest.
You are naive, or willfully ignorant, if you don't see through this.
On numerous posts you have declared persons like myself a non-Catholic "Protestant" an apostate and going to hell...right along with the “heathens...and animists.”
Well, which is it...?
Does Christ save me or the Catholic Church ?
Of course not!
Rome has OTHER ways to do THAT!!
"One indeed is the universal Church of the faithful, outside which no one at all is saved, in which the priest himself is the sacrifice, Jesus Christ, whose body and blood are truly contained in the sacrament of the altar under the species of bread and wine; the bread (changed) into His body by the divine power of transubstantiation, and the wine into the blood, so that to accomplish the mystery of unity we ourselves receive from His (nature) what He Himself received from ours." — Pope Innocent III and Lateran Council IV (A.D. 1215)
Therefore, if anyone says that it is not by the institution of Christ the lord himself (that is to say, by divine law) that blessed Peter should have perpetual successors in the primacy over the whole Church; or that the Roman Pontiff is not the successor of blessed Peter in this primacy: let him be anathema. — Vatican 1, Ses. 4, Cp. 1
