I lot of questions, yet you only ask them and make assumptions based on what you may or may not know, very little in the way of documentation that disproves the contentions offered in the linked article. Does 500 languages sound like too many? Did you know there are now nearly 7000 known languages in the world? Is it out of the possibility that many of those people who heard the gospel preached in their OWN tongue that first Pentecost day also went back and wrote what they had heard? Is it also out of the realm of possibility that these people started assemblies of believers in their own lands and received the writings of the Apostles and their disciples and translated those, too?
It IS undeniable that the Roman Catholic Church diminished the authority of Scripture and forbid the laity to read the Scriptures IN their vernacular and it is also undeniable that the Latin Vulgate that WAS the only permitted one, was full of its own errors and Roman Catholic biases. God, however, had other plans and it was HIM who preserved His word.
Amen, Amen, and Amen!
