I know, it gets complicated – you might want to check out Pray Tell’s Translation Directory. Briefly: The “Gray Book” is the final version prepared by ICEL, after having received feedback from all the national bishops’ conferences, which ICEL gives to the conferences for their approval. Sometimes conferences make a few amendments before they approve the Gray Book and send it to Rome for approval.
The value of this leak is that it allows us to compare more closely the relationship between the 2008 text as approved by conferences (perhaps with a few amendments not in this leak) and the 2010 Received Text approved by the Congregation for Divine Worship [CDW] in the Roman Curia. Now the whole world can see how drastically the CDW changed what it got from the national conferences.
Is there anyone out there who still doubts the infamous 10,000 number? Is there anyone out there who thinks (or dares to claim) that these changes made by Rome were in response to the amendments of the national conferences?
The truth is oozing out. There will be more.
