I can see the communion rule. But why no funeral? A great opportunity there to preach the Gospel. And after all, a human being in the image of God deserves a farewell, don’t they?
“But why no funeral?”
They could take that one very far. those who were divorced, those who had abortions, those who were gay, those who had pre-marital sex......
We all sinned, but it is their Church, and their right and responsibity to interpret their own beliefs, standards and rules.
Farewell yes. But a Catholic burial service is different from any other.
If the family wants to request a Catholic priest to preach the Gospel at the funeral home, the reception / memorial dinner or the graveside, hey, a powerful and blessed opportunity. But no Funeral Mass.
A Catholic funeral signifies that the deceased was in communion with the Church. It signifies that the deceased desired the Church to pray for him.
Although, being dead, the deceased cannot receive any sacrament, his funeral still signifies communion.
A person in a same-sex marriage proclaims rejection of communion with the Church. Without repentance before death, a Catholic funeral is irrational.
There are plenty of ways that people hold folk funerals these days, but a rite of the church should not be altered to suit an unrepentant sinner. That being the case, the church should also deny funerals to people who haven't been to confession since who knows when, who are openly cheating on their marriages, etc. And the church should refuse to marry about 50% of those who ask until they have satisfied educational requirements.
Rant over.
