Best go for a non-Christian (not actually sure it deserves the label 'humanist') service then!
Fancy a confused committal where the dearly departed is committed to Mother Earth and their spirit is set free to oblivion in the knowledge that because the people present will treasure their memories their life has found merit and meaning and they can rest safe in the knowledge that they lived for a purpose.
How's about being commended to 'all that is' and set free to be part of the whole realm of creation, tasking their part in the overall canvas of life and having the place they rest sanctified and hallowed to their memory for eternity?
The more I listen to people doing these services - especially the geezer what reads out cards, messages and emails as if it's a wedding - the more I wonder what some of these people are doing (other than making money out of the fact the customer knows nnnn 'Wasn't religious' so they offer something that is hopeless in oh so many ways!).
I am always surprised by the people who claim to have no faith and not be religious and the ways in which they cling to a hope of heaven, eternity and all that stuff. When I pointed out to one that what they'd delivered was the hope of Christianity coupled with some folklore and neo-confused pagan (ooooh, nature is so clever) tosh - the response was. 'Oh, but it gives them comfort to think there's more!'
Which is of course true but what I had before me was a snake oil salesman - offering hopelessness masquerading as hope and a terminal experience billed as something that with some confused continuance.
What makes it sadder is that some I have spoken to have told me how when the words, 'They weren't religious' are used by the person contracting the funeral then the potential for something 'humanist/non-religious' to be sourced is great. later though it transpires that this wasn't quite what the family might have wanted - they just didn't want to appear as if the deceased was an active Christian - and ended up with something quite different from that which they might have hoped for.
How very sad - and rather frustrating too :-(
