Considering that Atheists do not have a belief in an afterlife(usually) how would you hold a funeral for one?
Having been to a few funeral myself one of the most noticeable things I take notice in is that funerals are almost always held in a church and a pastor is present.
How would you make a funeral as untheistic and nonreligious as possible?
I personally wish to be cremated and have no funeral. I have never found death to be sad int he slightest bit.
I truly don't think being an atheist is supposed to make any difference there. Funerals, after all, are for the benefit of those who survive the deceased, not the deceased himself. They are rituals of remembrance, acknowledgement, mutual support and acceptance.
IMO it is a mistake to inform them by the faith of the deceased. They should be guided by the beliefs of the survivors instead, albeit in respectful ways that do not attempt to overrule the deceased's memory.
I also think this is one of several situations where the difference between religion and belief in God matters. Funerals
are religious or quasi-religious by their very nature - and like so many other religious matters, they are in reality quite indifferent to belief in God or to its absence. While there are those who seem to automatically jump to statements about God whenever they face the matter of mortality and its consequences, the two subject matters are very separate indeed. Atheists can and do miss their loved ones just like anyone else. We just don't (usually) claim to believe that there is an afterlife or anything of the sort.
