I told you, UCC can say whatever it wants, and if they want to embrace TUCC, fine, but a myriad of declarations from UCC does nothing to clarify where TUCC places its allegiance.
Finally, if you take the church's ZIPCODE and put it in the "Search for a UCC Church" search engine, you come up with Trinity UCC, and the pastor's name (yet to be updated) is Jeremiah Wright. Go here: http://www.ucc.org/find/chicago-trinity-ucc.html
Perhaps you should explain just exactly why you DON'T want Trinity UCC to be a member of the UCC denomination even though the UCC claims that it is.
