I see a secularization of ritual. People do love their celebrations; even JW's have their Memorials, weddings, CO visits, good-bye parties, etc. I don't see such things ending, they'll just be taken out of the realm of religion and replaced with observations of non-religious occasions like Stephen Foster Memorial Day (January 13th), Idaho Human Rights Day (January 17th), International Mother Language Day (February 21), ad infinitum. Hallmark will still sell cards, there will still be Lay-Away at stores, gifts will still be exchanged on certain of the days, but the "benefits" will not be connected with supernatural beings of any ilk. The lessons once associated with religion are already being taught as human qualities or character traits; instead of having a good or bad spirit within oneself, it's now possible to connect certain behaviors with genetic or environmental factors, for example.
I've thought a bit about this shift, and it seems to me that even die-hard religionists can agree that the trend exists; perhaps viewing it as a necessary stepping stone from the elimination of "false religion" to the establishment of "The Truth".
