After Robert Cardinal Sarah's retirement as Prefect of the Congregation for Divine Worship and the Discipline of Sacraments, the big question around the Vatican is who will take his place.

Informed sources say that Pope Francis would be looking at three possible options.

The first would be that Pope Francis would raise Archbishop Arthur Roche, 70, from the congregation's secretary to its prefect.

Archbishop Roche was appointed Secretary of the Congregation for the Divine Worship and the Discipline of the Sacraments by Benedict XVI in 2012. Before, he was president of the British International Commission on Liturgy from 2002 to 2012. He also served as auxiliary bishop of Westminster from 2001 to 2002, coadjutor Bishop of Leeds from 2002 to 2004, and Bishop of Leeds from 2004 to 2012.

During Pope Francis' pontificate, he has been a go-between Pope Francis and Cardinal Sarah in liturgical issues. He was entrusted with writing a commentary to the motu proprio Magnum Principium, which shifted the responsibility of translating liturgical texts to bishops' regional and national conferences. The comment came out along with the publication of the motu proprio.

In 2019, Pope Francis appointed Archbishop Roche as a member of the team to examine the appeals on delicta graviora, the gravest crimes dealt by the Congregation for the Doctrine of the Faith, which includes the sexual abuse of minors.

The second option is Bishop Claudio Maniago of Castellaneta. Maniago, 62, has been president of the Italian Bishops Conference's Commission on liturgy since 2015. In that position, he oversaw the new translation into Italian of the Roman Missal, which included a new version of the Our Father.

Pope Francis appointed Bishop Maniago as a member of the Congregation for Divine Worship, and in 2016.

The third option would be Bishop Vittorio Viola of Tortona. A member of the Order of Friars Minor, Viola, 55, has been a bishop since 2014.

Pope Francis picked Viola as bishop, raising him from his position of president of the Assisi Caritas. He had also been the Custodian of the Papal Basilica of Saint Mary of the Angels in Assisi. He got to know Pope Francis during the pope's visit to Assisi on Oct. 4, 2013, when he sat next to him during a lunch with the poor.

Viola was ordained a priest by Bishop Luca Brandolini, one of Archbishop Annibale Bugnini's closest collaborators.

Viola is also a good friend of Bishop Domenico Sorrentino of Assisi, who was secretary of the Congregation for the Divine worship from 2003 to 2005.

Pope Francis reportedly appreciated how Bishop Viola handled the parishes' re-organization in Tortona, and he showed strong decision-making skills. Bishop Viola was among the candidates to take over the position of Archbishop of Genoa. Pope Francis opted for a Conventual Franciscan in Genoa, Fr. Marco Tasca. But rumors insist that the pope had already decided to call Viola to the Vatican.
