Rocco’s summary of the contents of the Motu Proprio doesn’t say anything about the controversial Good Friday prayers for the Jews. But let’s take note of a couple of things. 1) It does say there are to be no private celebrations of this mass during the Triduum (which includes Good Friday); 2) priests will be able to have a public celebration of this mass if people request it, in addition to a mass or masses in the vernacular, but you don’t celebrate duplicate Triduum liturgies, so in these parishes the Triduum will continue to be celebrated according to the 1970 Missal; 3) this means that the only place the Good Friday liturgy will be observed according to the 1962 Missal will be in a personal parish, erected by the bishop, at which all the celebrations will be according to that missal–and not many bishops are likely to erect those, especially given the three year trial period called for by this Motu Proprio.
So my advice to my Jewish friends (who were concerned not only about its contents, but about it being released on Shabbat)? Shabbat Shalom.
