According to an official Vatican statement, Kim Davis was among "several dozen persons" attending a reception at the Vatican embassy, "the pope did not enter into the details of the situation," and "his meeting with her should not be considered a form of support."Moreover, it seems that the pope did not request Kim Davis be invited.
According to press reports, one man was likely responsible for Davis's
invitation: Carlo Maria Vigano, a conservative church official who was
appointed by Pope Benedict as Vatican ambassador to the United States
(formally called the "apostolic nuncio").
Having created an opportunity for lunatic fringe wingnut evangelicals to dishonestly
hijack the message of the pope's visit to the United States, Vigano
must now resign.
