How do Catholic funerals differ from non-Catholic ones?

Answer 1

A traditional Catholic Funeral depends on the culture that the funeral is being held in. The traditional Catholic Western Cultural funeral begins with a mass in which the body is blessed, mass is said, and the body is placed in the grave. the biggest difference is that there is a catholic mass in the funeral rights.

Answer 2

This is covered at the link below. It would appear that the Maori rites are held prior to the actual funeral which would be Catholic if the deceased had been a Catholic. So the Maori rites would be more like the viewing ceremony held the night before a funeral in the western Church, at which the mourners would welcome friends of the deceased, and perhaps pray the rosary or other prayers.
