But what do those in the know think about rank and file Catholic clergy and parishes making use of the Anglican Ordinariate's Roman Missal which should be for sale any day now? Might it happen?
I very much hope that our Rite will spread within the Anglophone Catholic world, quite simply because it is what that world needs. And it is clear (and very welcome) that Ordinariate congregations are not and will not be exclusive ghettoes. As a result of this, in parishes where there are Ordinariate clergy, laypeople from both backgrounds, 'Anglican Patrimony' and 'Diocesan', worship together. Thus Ordinariate Catholics with their Anglican Use, and Diocesan Catholics with their Ordinary and Extraordinary Forms, mingle, and have the capacity very much to enrich each other. Mutual Enrichment as advocated by Benedict XVI! Diocesan clergy have often asked me, as I have given talks to laity and clergy in many countries, whether they are allowed to use our admirable Rite, and I have had, with regret, to explain that the general answer is No (except in particular circumstances).
There are a couple of things we could do to help facilitate the growth and spread of what our particular charism has brought into the Catholic Church for the benefit of all the members of that Church.
(1) There could be a protocol something like this:
When this Rite is used in circumstances where there are substantial numbers of worshippers who are not members of the Ordinariate, the Celebrant may, at his discretion and for pastoral reasons and after consulting the Ordinary, omit the Prayers of the People, the Penitential Rite beginning Ye that do truly, and the Prayer after Communion beginning Almighty and everliving God.
(2) It could be enacted that non-Ordinariate clergy of the Roman Rite may celebrate our Use iusta pro causa, because it is in fact a lawful Form of the Roman Rite together with the Extraordinary and Ordinary Forms. It was part of the genius of Benedict XVI canonically to make it clear in Summorum Pontificum that the EF and OF are both equally forms of the Roman Rite, so that any Roman Rite priest can use either of them without needing any permission from anyone. By doing this he avoided the legal complications inherent in 'biritualism', which would have enabled unsympathetic bishops to sabotage his intentions. The same basic principle should analogously apply to the Anglican Form.
