Cardinal Joachim Meisner of Cologne was asked, “Could you envision celebrating a pontifical high Mass in the extraordinary form of the Roman rite?” His response:
As a Catholic Christian and in particular as a cardinal, I am bound to the entire liturgy of the Church – in every form which is celebrated in agreement with the successor of Peter. But as archbishop I have a particular ministry to offer, namely that of unity. Thus, the form that Pope Benedict XVI has termed “ordinary” is the standard for me.
Still, this unity also finds its expression in the liturgy in that we do not ignore those people who are attached to the extraordinary form of the Roman rite. In his motu proprio “Summorum pontificum” of 2007, the Holy Father expanded the possibilities of celebrating the liturgy in this extraordinary form. In the archdiocese of Cologne we take care to implement this: we have several churches in which the liturgy is regularly celebrated in the extraordinary form. But it is crucial – in the sense of the unity I mentioned – that those faithful who feel more at home in the extraordinary form also accept the ordinary form as such. That is the expressed wish of Pope Benedict XVI.
I take very seriously the desire for the celebration of the liturgy in the extraordinary form. I have tried to discover what motivates people who so highly value this form of our liturgy. What is important to them are periods of silence, the solemnity of the celebration, the devout atmosphere, and above all the space for one’s own prayer. Certain forms of expression such as Gregorian chant also touch them. I personally consider these aspects indispensable and treasure chant. These can and should have their place in the ordinary form of the liturgy. …
To your actual question: Until now, I have not celebrated a pontifical High Mass in the extraordinary form. Although I was ordained a priest in 1962 and initially celebrated Mass in the extraordinary form, today I would have to prepare extensively for it. At this time I see no reason to celebrate a pontifical High Mass in the extraordinary form.
