CNSNews reports:
As Catholic Church leaders, including Pope Francis, battle over whether divorced and remarried couples may receive Communion — although the couples are objectively in a state of serious sin, i.e., adultery — Cardinal Robert Sarah, head of the Vatican office dealing with Divine Worship and the Discipline of the Sacraments, said the Church’s teaching on mortal sin and Communion cannot change and that even a Pope cannot seek to circumvent or alter this divine law.
The dispute over Communion for divorced and remarried Catholic couples stems from Pope Francis’s letter Amoris Laetitia (The Joy of Love), which grew out of the meeting of bishops (synod) in 2014 and 2015, and was released as a document by the Pope in March 2016.
