<According to the article Fr Weinandy resigned his position after he made public the fact that he had written to the Holy Father. That is hardly ‘hoist with his own petard’, is it?>
I'm not sure how you think Fr. Weinandy's  preening arrogance and his cynical manipulation of his position with the bishops' conference to advance his personal agenda invalidates the idiom I chose, but I'm not sufficiently invested in it to argue about it.
As for the criticism of this pope: apart from the screeching noise created in the far right corner of the church, this pope is by every measure the most popular, respected and well-loved pope since John XXIII.  History will remember Pope John Paul for his malfeasance and non-feasance in responding the the clergy sex abuse crisis. No pope in the modern era has done more damage to the church than did John Paul II.
