Below are excerpts from a post on catholicanarachy.org. I find the reflections both provocative and worthy of serious consideration.
Thanksgiving in the united states is a holiday observed by pious Christians without much thought. What could be more Christian than thanking God for the blessings God has given us? The reality of this “secular” feast day is, of course, much less innocent and much more monstrous than we assume. […]
…aside from the holi-day’s idolatrous core, there remains much to be concerned about. One is the obviously troubling history of the holiday and its relation to Native peoples. The story that is celebrated by mainstream white america is a lie, and indeed is not the story remembered by those who originally inhabited this land, which is a white supremacist story of extermination. And we Christians should not forget and should not fail to repent the fact that Christians and Christianity were complicit with this genocide, explicitly providing the theo-ideological justification for it.Secondly, the “blessings” that “we” (white, middle and upper class americans) celebrate are simply not shared by significant portions of the american population, let alone much of the rest of the world. Indeed, the poverty and misery experienced by many both inside and outside of the united states is not an accident of history, but is rather the dark underside of the “blessings” we feel so inspired to celebrate here in the so-called First World.
Third, in its “secular” form, this holi-day’s concept of “giving thanks” has become virtually unintelligible when God is taken out of the picture. This should make Christians concerned about who exactly we are thanking on such a holiday. In the absence of the Creator, what fills the “empty shrine” (in the words of Bill Cavanaugh) of the american empire on this holiday? Who or what are “we” thanking for “our blessings?” The fact is, the holi-day is delightfully vague, and this vagueness is precisely part of what makes american civil religion work.
Fourth, in the absence of any intelligible sense of true “thanksgiving,” we are left with a holiday that tends to be reduced to “being with family and loved ones,” something that is, of course, nice to do, but which can quickly become an opportunity for the virtual worship of family and blood ties, another important aspect of american civil religion. Jesus, despite what the Religious Right has done to him, could hardly be called a “family values guy,” and resisted such notions of blood ties in his own day. […]
Pro-life Christians who choose to be thoughtful about such things should be deeply troubled by the reality of Thanksgiving. Indeed, it is perhaps the holi-day par excellence of the culture of death [e.g. the slaughter of Native Americans]. Of course, the best option for Christians would be simply not celebrating Thanksgiving at all. After all, Christians have their own thanksgiving, only we use its Greek name, eucharist. It is a celebration of liberation and resurrection, not invasion and extermination. It is a celebration that embodies new familial relationships not based on blood or nationality but our common life in Christ. It is a celebration whose purpose is not to say “thank you for all the stuff we have when others are not so fortunate,” but rather “thank you for inviting all of us to this table.” And of course, the one we thank is the Author of Life, the One who is not to be replaced by sentimentalism or the idols of state, of “freedom,” of “choice” and the like. No wonder Jesus made the eucharist a vegetarian feast, a true foretaste of the banquet of the Kingdom of God.
