My friend is Mormon and married a Catholic in the Catholic Church.She agreed to raise the kids Catholic. She will go to Mass with her family most of the time when her husband is in town. She cannot take Communion. She does not go to the Mormon church, but sometimes they come to her house. If she dies can they have a funeral Mass in the Catholic Church? My husband says no.
No, an unbaptized person is not counted among the Christian faithful, unless they were enrolled as a Catechumen at the time of their death.
Here is the relevant canon law:
THOSE TO WHOM ECCLESIASTICAL FUNERALS MUST BE GRANTED OR DENIED
Can. 1183 §1. When it concerns funerals, catechumens must be counted among the Christian faithful.
§2. The local ordinary can permit children whom the parents intended to baptize but who died before baptism to be given ecclesiastical funerals.
§3. In the prudent judgment of the local ordinary, ecclesiastical funerals can be granted to baptized persons who are enrolled in a non-Catholic Church or ecclesial community unless their intention is evidently to the contrary and provided that their own minister is not available.
Can. 1184 §1. Unless they gave some signs of repentance before death, the following must be deprived of ecclesiastical funerals:
1/ notorious apostates, heretics, and schismatics;
2/ those who chose the cremation of their bodies for reasons contrary to Christian faith;
3/ other manifest sinners who cannot be granted ecclesiastical funerals without public scandal of the faithful.
§2. If any doubt occurs, the local ordinary is to be consulted, and his judgment must be followed.
Can. 1185 Any funeral Mass must also be denied a person who is excluded from ecclesiastical funerals.
