2002 Roman Missal since receiving the new Roman Missal on 4 April 2002 I have learnt that there are lots of differences between it and the 2000 Institutio Generalis.
Ministers in Masses discussing the liturgical laws based on the 2000 Institutio Generalis
New Rules are church law
In the press conference Cardinal Jorge Medina Estevez, prefect of the Congregation for Divine Worship and the Sacraments, is reported (by catholicnews.com) to have said that with the public availability of the texts the new rules are church law.
According to Canon 7 - 8 of the Code of Canon Law:
That "the new rules are church law" suggests the laws have come into force, rather than simply come into being. So there do not seem to have been changes to what was published in 2000 in the Institutio Generalis. If so, I believe my "Ministers in Masses" gives the laws for celebrating Mass in the Roman Rite today.
I have not yet seen the new Order of Mass, which was only published this week. But the Cardinal's comments suggest it does not contain significant changes.
It would be difficult to argue "the new rules are church law" means they have come into being, but are not yet in force. I think they came into being with their publication in 2000.
