Let me assist you. It was by Karl Rahner, given in his address at an American University on the occasion of his 72nd (I think) birthday. His speech was entitled "A courageous, new, worldwide theology." It is set out in full at the end of Richard P McBrien's book, 'Catholicism.'
He also states in the speech that he looks forward to this new theology which will not simply turn the pages of our "familiar friend, Denzinger" but will break new ground, listening to the wisdom from the East, hearing also the cries for freedom in Latin America and listening to the sound of African drums beating.
A wonderful piece of work. Such a theology also, he claims, will not demean those who have "gone before us - whose grateful children we are..."
Unfortunately, we got Ratzinger instead. Personally, I wasn't very grateful about that.
