Funny.... Jesus didn't speak Latin. And he came as a common man and fought all the traditionalists that deceived people into thinking keeping a man-made tradition would save people.
Easy, BigFinn!
Jesus didn't speak Elizabethan English either . . . and he said, "I did not come to abolish the law and the prophets but to bring them to fulfillment." And I'm sure you're aware of some of his other statements, "You are Peter and on this rock I will build my Church . . . whatever you bind on earth shall be bound in heaven . . . whoever hears you, hears me . . . " and "When the Spirit of Truth comes who proceeds from the Father and whom the Father will send in my name, he will lead you into all truth."
And how many "common men" do you know who can heal the sick, raise the dead, and then rise themselves in the glory of resurrection?
Beware facile responses that reduce Jesus' teachings to "aw shucks" and the Holy Eucharist to grape juice and crackers.
Jesus didn't speak Latin? In what language did He and Pilate converse? Scripture makes no mention of a translator being present.
Consider the discourse that Jesus had with the Roman centurion. It is very likely that that conversation took place in Latin as the centurion probably knew no other language and Jesus did as Jerusalem was a cosmopolitan city in the Roman Empire.
Another person that didn't read the article or chooses to be purposely obtuse. It's not about Latin, per say being a sacred language, but a dead language, in which meanings of words do not evolve like languages that are in current use. A language that doesn't change is best to express the Catholic faith which also does not change.
