My grandmother was a devout catholic...and had a catholic mass funeral. She was cremated; but, as others on this thread have pointed out, the urn was buried. I am not positive, but I believe she chose cremation, so she could be buried alongside her late husband (no room for a coffin). The cemetary even had a permanent altar and benches, with a spot for the urn to go - for a ‘graveside’ service. I was surprised that the catholic church dealt with cremation, but it apparently does.
Being a Catholic, I researched this. Apparently the Church is alright with the practice as long as the remains are held together. So, so much for my plans of being scattered over Venice Beach...
