That might be a little exaggeration, but the Italian journalist Andrea Tornielli has posted on his blog Sacri Palazzi:
The nomination of Msgr. Guido Marini, of the clergy of Genoa, as head of the Office of liturgical celebrations of the Pope, replacing [Archbishop] Piero Marini (who will be nominated as head of the Pontifical Commission for Eucharistic Congresses) will be announced at the beginning of the coming week (probably even Monday). Guido Marini will take possession of the appointment after 21 October, that is, after the Pope’s visit to Naples. But on that occasion he will already be present together with [his] predecessor.
La nomina di mons. Guido Marini, del clero di Genova, a capo dell’Ufficio delle celebrazioni liturgiche del Papa, in sostituzione di mons. Piero Marini (che sarà nominato a capo del Pontificio comitato per i Congressi eucaristici) sarà annunciata all’inizio della settimana entrante (probabilmente già lunedì). Guido Marini prenderà possesso dell’incarico dopo il 21 ottobre, cioè dopo la visita del Papa a Napoli. Ma già in quella occasione dovrebbe essere presente insieme al predecessore.
I think not a few of us will be getting up pretty early on Monday to read the appointments.
Fr. Finigan says:
As the former Archbishop of Southwark, Most Rev Michael Bowen, once said in response to a rumour, "For all I know, it may very well be true."
