Robert Jenson on theology and ecumenism
“It is becoming increasingly clear that reestablishment of ecclesial fellowship between East and West and within the West across the divisions begun at the Reformation will not occur by any straightforward continuation of [the efforts of modern ecumenism]. It increasingly appears that no degree of theological convergence can by itself suffice to reestablish communion once broken. An act of God is needed.
“Nor need this be a pessimistic prediction. The church must regard waiting as the most creative of activities, since she apprehends fullness of being only in the coming Kingdom. And God may act tomorrow. In the meantime, it is a great blessing specifically to theology that we need not wait for the church to be undivided to do theology for and even of the undivided church. For theology is itself a form of the waiting we must practice.”
