Funeral ceremonies are for the survivors, but the planning
is for the living. Not the dead. They are already in the next life.
My parents were shocked to their core when they told my brother and me how they wanted their remains to be handled and the funeral ceremonies conducted.
I agreed and promised to do my duty, although, personally, if that (insert worst possible insult) church they go to should burn to the ground with every single christianist in the congregation and their (insert insult, see above) pastor sealed inside, my only regret would be that they'd all die of smoke inhalation before they could burn to death, alive.
Still, that is irrelevant, their wishes are what counts. So, putting aside my own feelings, I said yes.
My super-duper-ultra-right-wing-christianist brother hit the ceiling. No way, no how, uh-huh were still usable body parts to be removed first. Under no circumstances. He'd prevent it.
Ditto their cremation, afterwards.
And so on.
In the end, my parents had every single possible (and many near-impossible) scenario pre-configured, written out by their lawyer and brought to the attention of the local court. The local hospitals, the funeral home responsible, their church (may they all die of Hodgkin's with an allergy to opiates), the crematorium, the mausoleum...right on down to which version of the Bible, which verses, which sermon, which hymns, who speaks, who doesn't, etc...
I would have carried out their wishes because I had promised, not because I agreed with them on many points. My brother caused them much distress on a topic which needs must be discussed at a time when all are healthy and well, not when emotions are out of control and grief governs.
I know, when the time comes, he will make things difficult despite the clear rules my parents laid out. No idea what to do then, christianists don't give a tinker's damn about laws and agreements...but that church only get's a substantial donation if my folks' funerals are held in accordance with their wishes. That is, I think, a smart move. You can always count on christianists to put money ahead of any and everything else.
Oh, and, yes - the church has signed a release in advance, that I will be permitted to attend the funeral with my partner and may visit them at the mausoleum (it would be on church burial grounds, sigh) at will. That one cost them $10,000, upfront. Just love me them christianists, yes I do.
