To bury the dead is one of the corporal works of mercy, but, I don’t know that the Church mandates a funeral be performed.
Peoples views on the whole funeral thing has changed over the years, plus costs have skyrocketed.
For me personally, I don’t believe in embalming, so a public viewing wouldn’t be allowed due to civil laws. Also, I don’t have much family left, so why go through all of the expense of a visitation, funeral, and a procession?
My plans, at this point, are to be cremated as soon as possible, then, private burial with a priest officiating, and then whatever family I have left can do what they want.
