Is it possible for an individual to divorce and remarry -- and still take part in communion in the Roman Catholic faith?
The topic has caused some controversy in the curia currently.
"We encourage divorced persons who wish to marry in the Catholic Church to seek counsel about the options that exist to remedy their situation, including the suitability of a declaration of nullity when there is no longer any hope of reconciliation of the spouses," according to the U.S. Conference of Catholic Bishops.
Pope Francis, the head of the Catholic Church, released an apostolic exhortation called Amoris laetitia in 2016.
Some bishops have issued guidelines on Amoris laetitia that allow, in some cases, divorced and remarried Catholics to receive Holy Communion.
"The eighth chapter of the exhortation deals with how the church should treat couples that live in so-called 'irregular situations,' such as those who have been civilly remarried without obtaining annulments of their first marriages," The National Catholic Reporter notes. "In the past, such couples had been barred from taking Communion."
In the Catholic faith, if a marriage does not meet certain requirements to be a "sacramental marriage," an annulment may be granted for the couple.
"We must lead them as good pastors until ... [such] point that they could accept completely the Christian doctrine and Christian life and our understanding," Gerhard Cardinal Muller, prefect of the Congregation for the Doctrine of the Faith at the Vatican, said on "The World Over with Raymond Arroyo" on the EWTN's Global Catholic Television Network. Arroyo is also editor-at-large at LifeZette.
The pope is merely an interpreter of the words of Jesus Christ, Muller said. The pope's Amoris laetitia goes against the words of Jesus, according to Muller.
Marriage is between one man and one woman, according to the biblical understanding of marriage.
During the act of penitence, "You must have the clear will to not sin in the next opportunity," Muller told Arroyo. "In this case, if they are ready to leave us ... But it not possible to live with two legal wives -- with one is with sacramentally marriage and the other only civilly."
"For us, dogmatic and pastoral is the same thing," he said.
The cardinal released a new book, "The Cardinal Muller Report," in February 2017.
