Archbishop Viganò, the retired nuncio to the United States, has now issued his third attack on the papacy of Pope Francis. In his first, in August, he called on the Pope to resign. Viganò alleges that Francis has deliberately facilitated the appointment of homosexual clergy to senior positions in the Catholic Church, and that the root cause of the sex abuse crisis is “the scourge of homosexuality”. The great majority of priests implicated in abuse are gay, he says, implying cause and effect; and they are protected from censure, civil or ecclesiastical, by their gay superiors.
