They make some people feel better, but not me. It helps, I imagine, if one is not as antichurch and antireligious as I am. And if one doesn't mind showing emotion in public (which I do).
Where a funeral takes place makes a big difference, I think (and, obviously, the degree to which one is grieving). Of the church funerals I've attended, I preferred the Catholic one, because the ritual was straightforward, codified, and traditional. But the three at a horrible, more evangelical joint where the preacher insisted on singing pop schmaltz, even once when the family asked that he not do so, were painful (oddly, one was better than the others because the corpse was given military honors; here, again, I think the rigid ritual made things easier to stomach). And then there was a weird double-religious graveside service for the sixteen-year-old son of a friend of mine where each of the classmates put a rose in his grave (weird because with all his talk of the misery of life on earth and the glories of the hereafter one of the ministers seemed to be recommending suicide).
Good luck, Andy. Sorry you have to go through this. And sorry for your wife, too, of course.
