John B. Cobb Jr. argues in his article “Guests at the table: Being transformationist in a pluralistic world” [Christian Century, August 10-17, 1994]:
Will the other traditions experience the pluralistic situation in a similar way [learning from others]? Will they seek to be transformed by interaction with one another and with us? Such tendencies exist. But from my Christian perspective most other traditions appear less open to transformation. As Wolfhart Pannenberg pointed out some years ago, most traditions find their completion in the past, whereas Christians look forward to a fullness that we do not yet possess.
This little snip does not do justice to the whole article (which anticipates some criticisms that might be raised).
