Williamson sent the Pope a letter expressing his regret about the problems that he had caused, but did not retract his statements. On 4 February 2009 the Vatican Secretariat of State issued a note stating that Williamson would have to distance himself unequivocally and publicly from the opinions that he had expressed before he would be permitted to act as a bishop within the Church. Williamson responded that he would do so only after looking at the historical evidence for himself.
