For some hundreds of years the Roman Catholic church denied people the Scriptures in their own language.If the Catholic Church was inspired enough to preserve scriptures and Canonise the Bible itself, then it is inspired enough to tell us what it means.
In 1400, a new law, De Haeretico Comburendo ('On the Burning of Heretics'), ordained for the first time in England, the burning of those regarded as heretics. in 1407, the 'Constitutions of Oxford' were introduced:
'The translation of the text of Holy Scripture out of one tongue into another is a dangerous thing; as blessed Jerome testifies, because it is not easy to make the sense in all respects the same; as the same blessed Jerome confesses that he made frequent mistakes in this business, although he was inspired: therefore we enact and ordain that no one henceforth do by his own authority translate any text of Holy Scripture into the English tongue or any other by way of book, pamphlet, or treatise. Nor let any such book, pamphlet, or treatise now lately composed in the time of John Wicklif aforesaid, or since, or hereafter to be composed, be read in whole or in part, in public or in private, under pain of the greater excommunication, till that translation have been approved by the diocesan of the place, or if occasion shall require, by a provincial Council. Let him that do contrary be punished in the same manner as a supporter of heresy and error.'
Well they're not wrong about Jerome making mistakes, but taking the two laws together, it meant that those wishing to read the Scriptures in their own language could be burned as heretics, and quite a few of them were, before Martin Luther was born. So to say that the Roman Catholic church preserved the Scriptures is simply not true. Rather, it hid the Scriptures from the people to preserve its own errors and illegitimate power.
