appears to have made an impact on Benny - he resigned and objectively, his papacy will be remembered as *failed*.
To my points:

Key - In a dramatic gesture of reconciliation, Pope Benedict XVI met Sept. 24 with his former colleague and longtime nemesis, Swiss Catholic theologian Hans Küng During a four-hour session that stretched over dinner, the two men essentially agreed to disagree on doctrinal matters. The pope offered warm praise for Küng's efforts to foster dialogue among religions and with the natural sciences, while Küng expressed support for the pope's commitment along the same lines. (note - citing *respect* for each other....not sure Weinandy's letter is respect).
Moreover, Kung and Benny met.....Weinandy's track record is to work in secret and make judgments.  No dialogue; violates natural law; etc.
On the surface, you raise an issue but it is apples to oranges when you stretch to Kung/Benny.
