3rd Plenary Baltimore (Since there are 3 plenary councils and 9 provincial councils in Baltimore, as well; you need to specify) also reaffirmed the 1st and 2nd Plenary Baltimore findings… which include a ban on any rite other than the Roman Missal within the US (1st Plenary Council of Baltimore). Given that the Dominican Missal, 5 byzantine rite churches sui iuris each with 2 or 3 forms of divine worship equal to the mass, and the Chaldean, Maronite, Syro-Malabar, Armenian, and Coptic Churches sui iuris all with 2 or more forms of divine worship are all in use in the US, the plenary council decisions need to be taken with careful consideration. A great many of their provisions are no longer upheld.
