Well then, did they immediately expend every effort to make mass copies of the original manuscripts and send them out to the Christian world so that they could make their own decisions as to what truly was the original unchanged word of God? Once again, No!
RESPONSE: Actually, this IS what has effectively happened. Churches and Bible Societies have appointed scholars to investigate the differences and determine what was originally written. The result is the work of the United Bible Societies. This group produces a Greek New Testament which has been used for most modern translations.
So what did they do?  Let us ask Rev. Dr. George L. Robertson.  In his book 
“Where did we get our Bible? he writes: 
 
“Of the MSS. of Holy Scripture in Greek still existing there 
are said to be several thousand of varying worth ... Three or four 
in particular of these old, faded out, and unattractive documents 
constitute the most ancient and the most precious treasures of 
the Christian Church, and are therefore of special interest.”  
 
First in Rev. Richardson’s list is the “Codex Vaticanus” of which he says: 
“This is probably the most ancient of all Greek MSS. now 
known to exist.  It is designated as Codex ‘B.’  In 1448, Pope 
Nicholas V brought it to Rome where it has lain practically ever 
since, being guarded assiduously by papal officials in the 
Vatican Library.  It’s history is brief: Erasmus in 1533 knew of 
its existence, but neither he nor any of his successors were 
permitted to study it... becoming quite inaccessible to scholars, 
till Tischendorf in 1843, after months of delay, was finally 
allowed to see it for six hours.  Another specialist,  named de 
Muralt in 1844 was likewise given an aggravating glimpse of it 
for nine hours.  The story of how Dr. Tregelles in 1845 was 
allowed by the authorities (all unconscious to themselves) to 
secure it page by page through memorizing the text, is a 
fascinating one.  Dr. Tregelles did it.  He was permitted to study 
the MS. continuously for a long time, but not to touch it or to 
take notes.  Indeed, every day as he entered the room where the 
precious document was guarded, his pockets were searched and 
pen, paper and ink were taken from him, if he carried such 
accessories with him.  The permission to enter, however, was 
repeated, until he finally had carried away with him and 
annotated in his room most of the principle variant readings of 
this most ancient text.  Often, however, in the process, if the 
papal authorities observed he was becoming too much absorbed 
in any one section, they would snatch the MS. away from him 
and direct his attention to another leaf.  Eventually they 
discovered that Tregelles had practically stolen the text, and 
that the Biblical world knew the secrets of their historic MS.  
Accordingly, Pope Pius IX ordered that it should be 
photographed and published; and it was, in five volumes which 
appeared in 1857.  But the work was very unsatisfactorily done.  
About that time Tischendorf made a third attempt to gain access 
to and examine it.  He succeeded, and later issued the text of the 
first twenty pages.  Finally in 1889-90, with papal permission, 
the entire text was photographed and issued in facsimile, and 
published so that a copy of the expensive quartos was obtainable 
by, and is now in the possession of all the principle libraries in 
the biblical world.”

What were all of the Popes afraid of?  What was the Vatican as a whole 
afraid of?  Why was the concept of releasing the text of their most ancient copy 
of the Bible to the general public so terrifying to them?  Why did they feel it 
necessary to bury the most ancient copies of the inspired word of God in a dark 
corner of the Vatican never to be seen by outside eyes?  Why?  What about all 
of the thousands upon thousands of other manuscripts which to this day remain 
buried in the darkest depths of the Vatican vaults never to be seen or studied by 
the general masses of Christendom?
