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?
Despite the fact that Cardinal di Nardo’s statement was not unduly critical of him there was no way that he could continue in his position as consultor to the USCCB.
I have lived under seven popes so far and the amount and type of criticism levelled against this Pope during his short reign is unprecedented. St John Paul II and Pope Benedict XVI may not have been popular amongst the progressives but their orthodoxy was never called into question.
