It seems almost certain that the USCCB will set Advent 2011, that is the Advent after next as the official date that the new translation of the Mass will begin being used in Catholic Churches in the United States.
I've discussed the new translation several times, as well as why the catechist should be interested and involved in this change.
It is important that the catechist understands the framework of the change. Beyond the very good reasons for a new translation, the facts of the translation itself should be known and be able to be explained by the catechist.
To begin with the previous ICEL translation is of the Roman Missile promulgated in 1975. In the United States the actual translation used is not the final approved translation, but still contains some parts, the creed for example, where a different translation based on an earlier draft was used.
In 2000 the original Latin edition, which contains some minor revisions, was approved. It was issued in 2002 and is called the Third Edition of the Roman Missal. In 2008 an amended version of this missile was issued which corrects some misprints in the original years 2000 version. This is the version from which the new translation is taken.
There are significant changes to some parts of the Mass prayed by the people and many parts of the Mass prayed by the priest. Without proper preparation many of the faithful will be unnecessarily confused by these changes. It is the responsibility of each pastor, using the resources provided by their bishop and with the help of his parish catechists to prepare the faithful for the use of this new translation.
We have what appears to be a long time to accomplish this catechisis. It will be many month before official volumes of the Sacramentary are available (though parishes should start thinking about budgeting for the new books they will need, as well as the training materials they will need.) However if we don't prepare for the tasks we will have to face next year in the preparations we will not be in a position to ensure a smooth transition.
So if you are a catechist seek out training on the new translation. many diocese have already started to hold training classes of their priest and catechetical leaders. Lots of information is available on line. Start with the USCCB site.
Get to work, time's fleeting.
