The UCC accepts all religious books as equal.
They are the product of many mergers - Congregational, Evanelical and Reformed, etc.
The UCC is so irrelevant and unknown today that they only make the news with this video and Rev. Jeremiah Wright's racist rants, not to mention his memorable sermon: "God bless America? No! God _____ America."
The UCC is the final step of Pietism, a radical atheism wrapped in sanctimony.
