Redemptionis Sacramentum:

Here are some of the juicy bits:

"[93.] The Communion-plate for the Communion of the faithful should be retained, so as to avoid the danger of the sacred host or some fragment of it falling."

There was some question about this, it is glad to see it made clear.

"[106.] However, the pouring of the Blood of Christ after the consecration from one vessel to another is completely to be avoided, lest anything should happen that would be to the detriment of so great a mystery. Never to be used for containing the Blood of the Lord are flagons, bowls, or other vessels that are not fully in accord with the established norms."

Very interesting and unexpected.

"[112.]...Except in the case of celebrations of the Mass that are scheduled by the ecclesiastical authorities to take place in the language of the people, Priests are always and everywhere permitted to celebrate Mass in Latin."

This is good, as in some places it has been claimed that a diocesan bishop has "forbidden" the celebration of the Mass in Latin.

"[114.]...While it is permissible that Mass should be celebrated for particular groups according to the norm of law,203 these groups are nevertheless not exempt from the faithful observance of the liturgical norms."

Take that Lifeteen.

The segment on vestments is also interesting. Commending not excercising the option of omitting the dalmatic. Forbidding the omission of the Chausable when there are even white Chausables to be worn. Note the prohibition of not wearing an alb, even when a religious habit is worn. Number 128 notes that priests must wear a cassock and surplice when participating in mass not as celebrant or concelebrant!

The prohibition on lay people homilizing is of course reiterated.

The use of extraordinary ministers of Holy Communion is strictly curtailed.

Also great is the section deliniating that some of these norms are grave matter.

This is especially helpful:

"[183.] In an altogether particular manner, let everyone do all that is in their power to ensure that the Most Holy Sacrament of the Eucharist will be protected from any and every irreverence or distortion and that all abuses be thoroughly corrected. This is a most serious duty incumbent upon each and every one, and all are bound to carry it out without any favoritism."
