Latin was/is the language of the Catholic Church. The Latin etymology of words are closer to the Aramaic and Hebrew than are English and words of other languages. English and other languages have about ten times as many words--synonyms that are close to the original English words, but still a bit different. To make things more complicated, while Hebrew and Latin don't change--other languages do.
So, while you jump up and down claiming the Catholic Church did not want unauthorized translations, there was a very good reason for it. Second, even the authorized translations needed someone well-versed in the original languages to explain the nuances a translation could not capture. Other denominations dismissed this, claiming the Holy Spirit could bridge that gap. That's kind of like claiming the Holy Spirit will cook tonight's dinner.
Yes, the way you explain Catholic doctrine, the original is indeed lost and scrambled as it comes out of your mouth. Mormons should leave Catholic doctrine and dogma explanations to Catholics.
Not only on this site, but on other religions forums as well: Say I had no religious background but was interested in investigating. Do you know why I would almost immediately dismiss Mormonism? Because Mormons are forever bashing Jews and Catholics--and by association, the Orthodox. If I were someone looking for a religion, I would quickly dismiss Mormonism because of such a strong image of Mormons sitting around on Sunday bashing people of other faiths and denominations.
We can present our own faith without bashing the faith of others. As I have said many times: While I have no regard for Joseph Smith, I do believe God meets us where we are. If God brought Adam and Eve along, He can certainly be present and bring your Church along as well. Jesus and the Holy Spirit are certainly more powerful--not to mention more true--than Joseph Smith. I, as a Catholic believe this.
What is disturbing is your lack of faith that God is also able to be present in the Catholic faith or the Jewish faith--any other faith--and guide them as well. The world has been redeemed, and God abandons no one.
