These kinds of declarations, honoring the role of religions in this country, are fascinating. On the surface level they are just fluff or a way of stroking the fundamentalist supporters of the Republican party. But on another level they are a step towards a Dominionist country: a Christian theocracy. Or theocrazy, really.
All those "whereases" in the declaration are worth reading, to see what it really says. It's not about "religion at all" but about Christianity, and the urgent need to have the government run on Christian principles. Note this part:
Resolved, That the United States House of Representatives----
(1) affirms the rich spiritual and diverse religious history of our Nation's founding and subsequent history, including up to the current day;
(2) recognizes that the religious foundations of faith on which America was built are critical underpinnings of our Nation's most valuable institutions and form the inseparable foundation for America's representative processes, legal systems, and societal structures;
(3) rejects, in the strongest possible terms, any effort to remove, obscure, or purposely omit such history from our Nation's public buildings and educational resources; and
(4) expresses support for designation of a `American Religious History Week' every year for the appreciation of and education on America's history of religious faith.
The bolds are mine. Note the "politically correct" use of the term "religion" here.
