Pope Francis speaks with the media onboard a plane during his flight back from Tallinn after the final leg of his visit to the Baltic states, Estonia.
Pope Francis also implored Catholics around the world to pray every day throughout October for the church to win out over the devil's assaults.
The president of the US bishops' conference welcomed Pope Francis' pledge to fight attempts to cover up cases of sexual abuse and to stop offering special treatment to bishops who have committed or covered up abuse.
The report said he had allowed accused priests to be reassigned or reinstated.
Speaking in April, His Holiness wrote: "We should not think of the devil as a myth, a representation, a symbol, a figure of speech or an idea". He paid a very high price for this unity and our mission is to take care that the people not only remain united, but become witnesses of the Gospel "That they may all be one, as you, Father, are in me and I in you, that they also may be in us, that the world may believe that you sent me" (Jn 17.21). In addition, it was hit sexual scandals, in particular in Germany, USA and Chile.
Numerous conservative Catholic activists and commentators, though, considered him too tolerant of the LGBT community and too liberal on some other issues.
Cardinal McCarrick "was strongly exhorted not to travel and not to appear in public so as not to provoke further rumors", Cardinal Ouellet said, but "it is false to present these measures taken in his regard as "sanctions" decreed by Pope Benedict XVI and annulled by Pope Francis".
Ouellet's letter marked the Vatican's first direct response to Vigano's 11-page denunciation published August 26 in which he accused two dozen Vatican and US church officials of covering up for McCarrick since 2000, and demanded Francis resign for his role in the scandal.
That could mean Wuerl's role as a "chief conduit" between the U.S. Church and Francis will stay in place, and his influence with the pope is unlikely to be diminished - if anything, since his retirement may afford him more time in Rome, it might even grow.
Vigano released a second statement on September 29 saying that the Vatican has yet to respond to his accusations and that Francis has "compared me to the great accuser, Satan, who sows scandal and division in the Church - though without ever uttering my name".
On Sunday, a top Vatican official issued a scathing open letter accusing Viganò of mounting a "political frame job devoid of real foundation" and contesting his accusations against the pope point by point.
So, he is convinced that Satan is behind the sexual violence, as well as differences that split the Church. Michael is mentioned several times in the Bible as the leader of the angels who ousted Lucifer, the fallen angel, from paradise.
"I renew the invitation to everyone to pray the Rosary every day of the month of October ending it with the antiphon "Under Your protection" and the prayer to St. Michael the Archangel, to repel the attacks of the devil who wants to divide the Church", he said.
He asked the Catholic weekly to read the special prayer. Be our defence against the wickedness and snares of the devil.
