Detroit, Jan. 26 (CWNews.com) - Bishop Thomas Gumbleton, a Detroit auxiliary and an outspoken proponent of liberal causes, has hinted that he may refuse to submit his resignation, as required by Church law, when he reaches his 75th birthday. Bishop Gumbleton, who turns 75 today (January 26), told the Toledo Blade that he was reluctant to submit his resignation. He complained that the Vatican response to resignations is "so arbitrary-- some of them they ignore, but if you are the least bit progressive, they accept it immediately."
