That no more justifies the stated contrasts btwn the church of Rome and that of the NT church anymore than it does the Mormons, who essentially make the same claim, and renders your church to be an autocratic organization that is not subject to only wholly inspired substantive body of Truth.
I invite you to read the Catholic Bible, which is the original, and compare it to yours. See all the words that were changed or deleted from yours. You will be amazed.
Melian, I am a former (by the grace of God) faithful Mass-going RC CCD teacher and lector who actually read and studied the official (for America) Catholic Bible, so that is not going to help you. Traditional RCs even attack that Bible for good reason , while their favorite, the DRB, has very few differences from the KJV (which it influenced), apart from the long disputed deutros which only became binding ass part of the canon after the death of Luther , and only offers support for perhaps two RC distinctives, while contradicting other RC teaching as well as Scripture.
In addition, if you can find the original Bible you will be very famous, since everyone else only has copies of copies. And the Vulgate had so many versions and issues that it resulted in the first edition of the Latin Vulgate authorised by a pope, that of the scandalous works of Pope Sixtus V, the Sistine Vulgate which likely resulted the murder of its fanatical papal translator, besides only blaming copyists for its many errors. If you can find one you can be very rich (and hunted).
The more I read about the history of Roman Catholicism the more I am convinced it is not what was intended and has strayed away from the truth.
