I saw on the site of Andrea Tornielli that Card. Lehmann of Mainz considers Pope Benedict’s provisions in Summorum Pontificum to be foolish.
Mainz (kath.net) – “The fact that people may want a confirmation according to the old rite is nonsense [Blödsinn - stronger than "nonsense", I think], I believe.” So answered Cardinal Karl Lehmann, Bishop of Mainz, to a question in a reader forum of the “Allgemeine Zeitung”.However, he did not completely reject the Mass in the extraordinary form: “there are in our diocese, after all, five or six groups with the opportunity to celebrate them,” the Cardinal told the newspaper. But a confirmation according to the old rite? “I will not do it, they should go elsewhere.”
