Since the Pope keeps citing “reconciled diversity” and others have told me its the theology of Oscar Cullman, a Lutheran who was invited by both Popes John XXIII and Paul VI to the Second Vatican Council, I want to know more about his thought.
Here’s an excerpt, (with my emphases):
Like most other commentators, Cullmann saw in the church constitution Lumen Gentium the crowning achievement of the Council. As mentioned above, in Cullmann’s eyes, the
Council’s salvation-history approach led to a dynamic understanding of the church. The result exceeded his expectations. A pneumatological and eschatological understanding of the church replaced a more juridical and static approach. Cullmann welcomed in particular the now-clarified distinction between Christ, on the one hand, and the church, on the other.
This allowed for the assertion that the one church of Jesus Christ can find expression in various forms. In this sense did Cullmann interpret the subsistit in of Lumen Gentium
Eight. It was certainly emphasized in the Decree on Ecumenism that the Roman church is the church of Christ in its fullness (UR 3), but this is tightly bound up with the statement that many dimensions of the mystery of salvation exist also in other ecclesical forms.
Many Protestant observers at the council were critical of the approaches of Lumen Gentium and regretted the one-sided stress on the episcopal office, the validation of a
hierarchical understanding of office, and especially the lack of any critique of the statements about the papal office from the First Vatican Council. Cullmann rebuffed these criticisms and emphasized that one ought not be amazed that the Catholic church remained true to itself and stressed some of its foundational convictions anew.13
Cullmann would also have called many things into question. In his eyes the breakthrough in the Constitution on the Church consisted in the fact that one could place old dogmas
and new insights alongside each other. This is still not fully satisfactory, but it did mean that new ways were being opened; and this development, it seemed to Cullmann, was
irreversible.14 Thus, for example, the opening up of a synod of bishops was a decisive step to relativize the solitary power of the pope.
Any of my knowledgeable readers want to contribute something on this? A link, an informed opinion? Thanks
